This document describes a test to determine the standard consistency of cement paste. The test involves mixing cement with varying amounts of water and measuring how far a needle penetrates the paste using a Vicat apparatus. The standard consistency is achieved when the needle penetrates 4-7mm from the bottom of the mold after 30 seconds. This standard consistency percentage of water is then used to make cement pastes for other tests like setting time and soundness. The procedure involves mixing 650g of cement with a measured amount of water, placing it in the Vicat mold, and recording the penetration depth to determine the percentage of water that gives a penetration of 4-7mm.

Penetration test
This document discusses the penetration test used to measure the consistency of asphalt cement. It describes how the test is conducted by loading a standard needle into an asphalt cement sample submerged in a water bath at 77°F for 5 seconds. The penetration reading is recorded in 1/10 mm units and repeated three times to get the average. Higher penetration values indicate softer asphalt grades. Five standard penetration grades - 40-50, 60-70, 85-100, 120-150, 200-300 - are used to classify asphalt cement based on this test.
2 standard consistency of cement
1. The document describes a test to determine the standard consistency of cement paste, which is required for other cement tests and is between 26-33% water by mass of dry cement.
2. The test involves mixing cement and varying amounts of water (25, 30, 35% of cement mass) and measuring how far a 10mm plunger penetrates the paste, with 5±1mm indicating standard consistency.
3. Temperature and humidity can affect the test results, so the lab conditions are controlled at 20±2°C and 50% relative humidity minimum.
Determining the ductility of bitumen
This document describes a test to determine the ductility of bitumen. The test involves pulling a standardized briquette sample of the bitumen material at a constant speed and temperature until it ruptures. The distance the sample elongates before breaking is measured and provides a measure of the material's ductility. A higher ductility indicates the material is less brittle and more capable of stretching before failure. The test is important for engineers to evaluate whether a bitumen material is suitable for use in paving applications where ductility is required to prevent cracking.
Viscosity test 3
This document describes a test to determine the viscosity of bitumen. The test involves heating a sample to a specified temperature and measuring the time it takes for 50mL of the sample to flow through an orifice of a tar viscometer submerged in a water bath. Lower times indicate lower viscosity. The test is run at different temperatures depending on the type and grade of bitumen. Results provide the viscosity range for various common types and grades of bitumen to specify their fluidity properties.
Fineness test of Cement
1) The document describes a test conducted to determine the fineness of cement. Fineness is an important property that affects the rate of hydration and strength development.
2) The test involves sieving 100g samples of cement through a 90 micrometer sieve. The weight of residue retained on the sieve is measured and used to calculate the percentage fineness.
3) The results of tests on three cement samples showed average fineness of 94.07%, indicating good quality cement. Proper procedure and precautions were followed to ensure accurate results.

6 tensile strength of cement
The document summarizes a laboratory experiment to determine the tensile strength of cement. Mortar samples were created with a 1:3 mix of cement and sand, and tested after 1 day. The tensile strength was calculated by dividing the failure load by the cross-sectional area. The results were then compared to Iraqi standard specifications to determine if the cement passed requirements for its tensile strength after 1 day.
Standard consistency
The basic aim is to find out the water content required to produce a cement paste of standard consistency as specified by the IS: 4031 (Part 4) – 1988. The principle is that standard consistency of cement is that consistency at which the Vicat plunger penetrates to a point 5-7mm from the bottom of Vicat mould.
How to determine Soundness of cement?
What is the Soundness of Cement?
What is mean by soundness of cement? This is what soundness definition in civil engineering says “The ability of cement to resist the expansion and retain its original volume is called Soundness of Cement.” This indicates that a perfectly sound cement will undergo minimum volume change.
What is the soundness test?
The soundness test measures the change in volume due to expansion. This expansion should not exceed 10 mm for OPC, rapid hardening cement and low heat Portland cements. If the expansion goes more than 10 mm on testing, the cement is said to be unsound.
The soundness test can be conducted by Le-chatelier method and Autoclave Method. Le-chatelier test detects unsoundness due to free lime only.

The compressive strength of hardened cement is the most important of all the properties. Therefore, it is not surprising that the cement is always tested for its strength at the laboratory before the cement is used in important works.
Why the compressive strength test of Cement is important? Compressive Strength Test on Cement mortar is calculated to find out whether the Cement conforms IS specifications or not and whether it can develop required strength or not when used in Concrete.
Any kind of strength testings are not done directly on Cement itself because of properties like shrinkage and cracking. So Compressive strength test on Cement either done in the form of mortar or concrete. In this article, we will take a look at the compressive strength test of cement mortar using standard sand conforming to IS 650-1991.
Normal Consistency and Sitting times of cement paste
This document describes procedures for determining the normal consistency, setting times, and fineness of cement through various tests. The normal consistency test involves adding varying amounts of water to cement to find the water-cement ratio that gives a paste with a penetration depth between 5-7 mm. The initial setting time is found to be 1 hour and 22 minutes, while the final setting time is generally between 10-12 hours. The Blaine permeability test measures fineness through the specific surface area, found to be 93.52 m2/kg for the sample tested.
CE244 LAB RAPORU
This document provides procedures for conducting normal consistency, set time, compressive strength, tensile strength, and flexural strength tests on cement paste and mortar samples. It defines key terms and outlines the steps to prepare and test samples using a Vicat apparatus and universal testing machine. The results from 7-day compressive strength tests on cement mortar cubes met the ASTM C52 specification of 83.6 psi. Running additional tests at 1, 3, and 28 days would have shown how strength increases over time.
TESTING ON CEMENT
Quality tests are conducted on cement to check its strength and durability for different construction uses. Tests can be categorized as field tests or laboratory tests. Field tests check for lumps, texture, and float time while laboratory tests include fineness, consistency, strength, soundness, heat of hydration, and chemical composition. The fineness test measures particle size using a sieve while the consistency test determines appropriate water-cement ratio using a Vicat apparatus. The strength test involves crushing hardened cement-sand cubes in a compression machine. The soundness test ensures cement does not expand after setting using a Le Chatelier apparatus.
Tests on cement
Cement tests can be divided into field tests and laboratory tests. Laboratory tests include fineness test, standard consistency test, setting time test, compressive strength test, soundness test, and tensile strength test. The fineness test measures the mean size of cement grains and finer cement results in earlier strength development but more shrinkage and cracking. The standard consistency test determines the percentage of water required to form a cement paste using a Vicat apparatus. The setting time test uses the Vicat apparatus to detect when cement paste reaches its initial and final set. The compressive strength test forms cement mortar cubes which are tested at 3 and 7 days to determine strength. The soundness test uses a Le-Chatelier apparatus to
Fineness of cement test
This document summarizes a student's experiment to determine the fineness of cement through sieve analysis. The student took three cement samples and weighed them before and after shaking them through a #200 sieve. The percentage of fineness was calculated for each sample and averaged. The average fineness of 75.67% was below the ASTM standard of 90%, indicating the cement cannot be used for concrete construction. Possible sources of error included insufficient shaking of the sieve and clogged sieve holes.
Normal consistency-Amit Payal
The consistency of cement test determines the amount of water needed to attain a standard consistency when mixing cement. This is done using a Vicat apparatus, which measures the depth the plunger sinks into the cement paste. The standard consistency is reached when the plunger penetrates 5-7mm from the bottom of the mold. The normal consistency can vary due to factors like temperature, cement composition, and fineness. It is tested according to standardized procedures to ensure proper hydration and strength of the cement.
Fineness test on cement
Fineness is tells about the particle distribution of cement. Fineness of is cement expressed in terms of total surface area of unit weight of of cement.

Tests of cement in concrete technology
Tests of cements can be categorized as either field testing or laboratory testing. Laboratory testing includes fineness test, standard consistency test, setting time test, strength test, soundness test, heat of hydration test, and chemical composition test. The fineness test determines the particle size of cement, which affects the rate of hydration and strength development. The standard consistency test finds the amount of water needed to produce a cement paste that can be properly worked. The setting time test identifies the initial and final set times of cement. The strength test evaluates compressive strength of cement mortar cubes. The soundness test checks for expansion of cement after setting. The heat of hydration test measures heat released during cement hydration. Chemical composition
EXPERIMENTAL BEHAVIOUR OF SELF COMPACTING CONCRETE USING GGBS WITH PARTIAL RE...
Concrete is Most widely used construction Material in the Modern Era because of its good Compressive strength and
high durability. As we know Concrete comprises a Mixture of cement, sand (fine aggregate), course aggregate and water
which makes up normal plain concrete, to increase the strength of concrete we can design the mix with greater Flexibility,
but the problems Arises in structure as load age, increaseof floors which demands increase of high strength concrete
and more steel. So, especially at the beams, columns joints heavy reinforcement meshing is done so that it becomes If
the concrete is not compacted then strength may not be achieved, so the solution for the problem is SCC which we call
it asself-compacting concrete. Were this SCC has ability to compact by itself Gravity and self-flow ability same strength
can be Here in the research, it is carried out self-compaction concrete to improve strength & make concrete economical
so, a mix is dispend of M30,M40 Grades with adding chemical admixture named poly carboxylic ether (ADVA960) , a
Retarder Basically Which also increases strength and workability &replacing cement with GGBS (Ground Granulated
Blast Furnace Slag) 40%&50% .The tests are carried out to find the increase in strength by adding chemical admixture &
replacing GGBS 40% & 50%.By the chemical admixture adding up to 2% Max were previous strength shows that adding
of chemical admixture greater than 2% which results to increase the initial setting time and decrease in the w/c ratio.

Normal Consistency of Hydraulic Cement | Jameel Academy
This report summarizes a test to determine the normal consistency of hydraulic cement. Four trials were conducted with 500g of cement and varying water-cement (W/C) ratios of 0.25, 0.27, 0.30 and 0.33. These trials resulted in penetrations of 25mm, 9mm, 5mm and 4mm respectively. From the relationship between W/C ratio and penetration, the standard consistency was determined to be 0.2875 at a penetration of 6mm. However, the average penetration of 10.75mm exceeded the standard of 6±1mm, suggesting errors in the test such as insufficient cement quantity and inaccurate penetration measurement timing. The purpose of the test was to find

This manual contains all the fundamental experiments performed on "PLAIN AND REINFORCED CONcRETE" in the field and laboratory
Properties of concrete
The document summarizes several tests conducted on cement to determine its properties and quality. It describes procedures for testing the fineness, consistency, setting time, soundness, tensile strength and compressive strength of cement. Fineness is measured by sieving cement and finding the percentage residue. Consistency is determined using a Vicat apparatus. Setting time tests use Vicat needles to find when the cement can no longer be penetrated or indented. Soundness ensures cement does not excessively expand when boiled. Tensile and compressive strength tests involve making mortar cubes or cylinders and testing them after curing.

This document analyzes the compressive strength of self-curing concrete made using Polyethylene Glycol (PEG400). PEG400 is used as an internal curing compound to prevent moisture loss from concrete and allow for more complete hydration. Tests were conducted on M20 grade concrete with 0-1.5% PEG400 by weight of cement. Results found that 0.5-1% PEG400 concrete had higher 7 and 28-day compressive strengths than plain concrete, with less cracking. PEG400 improved workability and water retention, allowing for better strength development over time compared to traditional curing methods.

Quality Assurance of Available Portland Cements in NigeriaInternational Journal of World Policy and Development Studies
The notable demand for the want of cement in our time has stimulated increment in cement production and increment in manufacturers to be had in our day. These in turn amongst others have brought about failure of buildings and other construction members. As a result, the need to ensure the quality of available cement in circulation is of utmost paramount. This research work studies the available Portland lime cement of grade 42.5 only, in Nigeria from such company as company A, company B, and company C. The qualities and properties of the Portland lime cement from every of the above-named companies were investigated and as compared. Properties like Fineness, Setting Time, Chemical composition, Specific gravity, Consistency, Loss of ignition, Strength (compressive strength, and flexural strength), Micro structural analysis were determined according to relevant BS EN 197-1 (2011) and (ASTMC) 150-92 standards. These tests were carried out with the usage of scanning electron microscope, X-ray fluorescence spectrometer, Vicat apparatus, compressive strength machine, consistency apparatus and Chatelier flask, among others. The results showed that the chemical composition mostly of CaO, SiO2, AL2O3 and MgO in the cement +are within the acceptable limit of 60.0-67.0, 17.0-25.0, 3.0-8.0 and 0.1-4.0 respectively in the BS 4550: Part 3 (1979). The results of the compressive strength acquired for all the cement have been a way beneath the standardized result expected for grade 42.5. These could partly be traced to the cement micro-structure as Company C with the best morphology exhibits better compressive strength than others. Improvement on the cement morphology by the manufacturers could lead to compressive strength improvement. It was also discovered that one of the important factors that would have contributed to the low compressive strength was excessive amount of silt/clay content material inside the sand used.Similar to Job 3 (20)

Height and depth gauge linear metrology.pdf
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.

Soundness test APPARATUS:- Weighing Balance VICAT Apparatus (contains) Plunger with the end of 10mm diameter and 50mm length Conical ring with lower distance of 70mm, upper distance of 60mm and 40mm height. Glass Graduates (200mL or 250mL capacity) Scraper Spatula Glass Plate Trowel RELATED THEORY: - CONSISTENCY: The percentage water requirement of cement paste at which viscosity of the paste becomes such that the plunger in a specially designed apparatus (known as Vicat's apparatus) penetrates a depth 5 to 7mm, measured from the bottom of the mould. CEMENT PASTE: The viscous mass obtained by mixing cement with water is known as cement paste. STANDARD PASTE: It is the cement paste for which the 10mm diameter plunger in a standard Vicat test penetrates by around 10mm. STANDARD / NORMAL CONSISTENCECY: Consistency which permits the Vicat plunger to penetrate to a point 5 to 7 mm from the bottom of the Vicat mould in this test. It is expressed as amount of water as a percentage (by weight) of dry cement. VICAT APPARATUS:
- 2. PLAIN AND REINFORCED CONCRETE-1 JOB NO.3 2January 24, 2018 A device shown in fig1 is used for determining the normal consistency and time of setting of portland cements that consists of a rod weighing 300 grams, having a needle in each end, and supported in a frame with a graduated scale to measure the distance to which the needle penetrates the cement. The height of cylindrical mold is 40mm. Figure 1: VICAT APPARATUS TEST SPECIFICATIONS:- i. Temperature and humidity The temperature of the air in the vicinity should be between 20-27.5 °C. The temperature of the mixing water should be between 21-25°C. The relative humidity of the laboratory should be less than 50 percent. ii. Amount of cement The amount of cement required for the test according to ASTM should be 650gm. iii. Mixing time The cement paste should be properly mixed and placed in specimen within the maximum time of3.75-4.25 min from initial contact of cement with water.

Make the cement paste by mixing the cement with water as per defined standard procedure. iv. Place the cement paste in the mold and fill it completely and remove the excess of paste from mold with help of trowel. v. Place the cylindrical mold on the should of Vicat apparatus in such a way that the needle will falls in the center of mold and set zero reading on the scale. vi. Allow the needle to penetrate in the paste for 30 seconds after 30 seconds note the readings from the graduated scale that how much needle penetrates in the paste. vii. Repeat the procedure by varying the amount of water until the needle is 4mm to 7mm above bottom of mold and note that amount of water OBSERVATIONS & CACULATIONS: Type of cement = Source of cement =
