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.

2. Tests are also described for determining water demand and the effects of admixtures on properties like setting time and strength.
3. Common admixtures include accelerators, retarders, air-entrainers, and water-reducers, which can improve concrete workability, permeability, cracking resistance and durability.
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
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.

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
Cement test
Cement is tested through laboratory and field tests to evaluate its properties and suitability. Key laboratory tests described in the document include:
- Fineness tests which measure particle size and surface area to determine reactivity.
- Setting time tests which ensure cement sets within specified time limits.
- Compressive strength tests where cement mortar cubes are crushed to determine strength over time.
- Soundness and loss of ignition tests which evaluate volume stability and carbon/moisture content.
Results of laboratory tests help ensure cement meets standards before use in construction projects.
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.

What is Consistency of Cement?
Consistency of Cement is amount of water required to initiate the chemical reaction between cement and water to make the uniform cement paste.
Define Standard Consistency of Cement?
Standard Consistency of Cement is defined as Consistency which will permit Vicat plunger with 10mm diameter and 50mm length to penetrate to a depth of 33-35mm from top of the mould.
Standard Consistency of Cement can also be defined as Consistency of cement which will permit Vicat plunger to penetrate to the point 5-7mm from the bottom of the mould.
Also Standard Consistency means the amount of water required to make Cement Paste Plastic.
The Mechanical Properties of Concrete Incorporating Silica Fume as Partial Re...
Concrete is the most important engineering
material and the addition of some other materials may change
the properties of concrete. With increase in trend towards the
wider use of concrete for prestressed concrete and high rise
buildings there is a growing demand of concrete with higher
compressive strength. Mineral additions which are also
known as mineral admixtures have been used with cements
for many years. Silica fume particles are 100 times smaller
than the average cement particle. Its handling and disposal is
a point of concern because of the environment concerns. Silica
fume is usually categorized as a supplementary cementitious
material. These materials exhibit pozzolanic properties,
cementitious properties and a combination of both properties.
Due to these properties, it can affect the concrete behavior in
many ways. In the present work, an attempt has been made to
use silica fume as a supplementary material for cement and to
evaluate the limit of replacement of cement for M20 grade
concrete. The main aim of this work is to study the
mechanical properties of M20 grade control concrete and
silica fume concrete with different percentages (5, 10, 15 and
20%) of silica fume as a partial replacement of cement.

Experiment No. 4 involves determining the particle size distribution of coarse aggregates through sieve analysis. The sample is dried and sieved through a series of sieves with progressively smaller openings. The mass retained on each sieve is measured and the percentages passing and retained are calculated. This allows evaluating whether the aggregate conforms to specifications for use in concrete. The procedure is simple but provides important information about the aggregate gradation.
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.
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
1) Sieve analysis ------->I.S.sieve NO.9 is used to test----->permissible limit for OPC is not more than 10% retained on I.S.SIEVE NO.9
2) Air permeability tests----->most commonly used in India is "BLAINE AIR PERMEABILITY TEST"
Experiment no 03 setting time of cement.
This test method is used to determine the time of setting of the cement by VICAT
needle apparatus.
The knowledge of the setting time of the cement is always helpful in deciding the time duration
to mix, transport, place and compact the concrete effectively.
We always prefer a larger initial setting time so that we can mix, transport and place the
concrete easily. According to ASTM specifications, the initial setting time shall not be less
than 45 min but in the field we prefer an initial setting time not less than 90 min.
A smaller value of the final setting time is always preferred in order to avoid large expenditures
on the formwork. According to most of the specifications, the final setting time shall not be
greater than 10hrs and shall not be less than (90 + 1.2 x (initial setting time)) min.
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.
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.

During Construction using concrete, cement paste, mortar certain time is required for mixing, transportation, placing, compacting and finishing. During this time concrete, mortar, cement paste should be in plastic condition and should not harden and it is mandatory that one should use the concrete before it starts to loose its plasticity. So How should someone know how long is concrete workable? and How much travel time is permitted for concrete?
Well its Setting time that tells us how long concrete is going to be workable. Now the question is What is Setting Time of Cement?
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.
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.
Unit1 l3-rvr
Cement has various physical properties that are important for quality control, including setting time, soundness, fineness, and strength. Standard tests are used to characterize these properties according to specifications. Setting time refers to initial and final set, which are affected by factors like fineness and chemical composition. Soundness ensures volume stability after hardening. Fineness impacts hydration rate and strength gain. Strength is typically measured via compression, tension, or flexion tests at various ages. Different types of cement are produced through adjustments to raw materials, chemical proportions, additives, and grinding degree.

COMPARATIVE ANALYSIS OF CHEMICAL AND PHYSICAL PROPERTIES OF MINI CEMENT PLANT...Journal For Research
This research is about analyzing the chemical and physical characteristics of cement and concrete. Cement can be classified based on its chemical properties. The sample taken for this research work is Kamal OPC 53 grade mini cement plant and Ultratech OPC 53 grade major cement plant. The difference can be analyzed by determining the chemical composition of the cement and its effect on physical properties of cement and concrete. Secondly, it is not necessary that in every structural member of a building, the cement used needs to be same. To determine that which cement is more suitable for which structural element this analysis is beneficial. Again, if any new type of admixture needs to be introduced in the concrete, it is important to understand the chemical composition of cement and how the new admixture may react with the cement. Also, this research is about how the changes in chemical composition of cement affect the physical properties of cement and concrete. It is noticed that due to lack in standardization of cement, even the same sample of cement gives different result.

Cement has various physical properties that are important for quality control, including setting time, soundness, fineness, and strength. Standard tests are used to characterize these properties according to specifications. Setting time refers to initial and final set, which are affected by factors like fineness and chemical composition. Soundness ensures volume stability after hardening. Fineness impacts hydration rate and strength gain. Strength is typically measured via compression, tension, or flexion tests at various ages. Different types of cement are produced through adjustments to raw materials, chemical proportions, additives, and grinding degree.

COMPARATIVE ANALYSIS OF CHEMICAL AND PHYSICAL PROPERTIES OF MINI CEMENT PLANT...Journal For Research
This research is about analyzing the chemical and physical characteristics of cement and concrete. Cement can be classified based on its chemical properties. The sample taken for this research work is Kamal OPC 53 grade mini cement plant and Ultratech OPC 53 grade major cement plant. The difference can be analyzed by determining the chemical composition of the cement and its effect on physical properties of cement and concrete. Secondly, it is not necessary that in every structural member of a building, the cement used needs to be same. To determine that which cement is more suitable for which structural element this analysis is beneficial. Again, if any new type of admixture needs to be introduced in the concrete, it is important to understand the chemical composition of cement and how the new admixture may react with the cement. Also, this research is about how the changes in chemical composition of cement affect the physical properties of cement and concrete. It is noticed that due to lack in standardization of cement, even the same sample of cement gives different result.

Properties of Cement
- Cement is tested in the field to check for lumps, consistency, and ability to float in water.
- Laboratory tests include setting time, soundness, fineness, and strength. Setting time tests use a Vicat apparatus to check initial and final set. Soundness tests use a Le Chatelier apparatus to check for expansion. Fineness is measured by the Blaine air permeability test. Strength is measured through compressive testing of cement mortar cubes.
- Common cement types include ordinary Portland cement, rapid hardening cement, sulphate resisting cement, Portland slag cement, and Portland pozzolana cement made by intergrinding clinker with fly ash or calcined clay.
all about Fresh concrete
Fresh concrete has several important properties from mixing until it hardens in its final location. Its workability, defined as the effort to manipulate it with minimum segregation, depends on factors like water-cement ratio, aggregate properties, time, temperature, and cement characteristics. Workability is measured using tests like slump and Vebe, which assess consistency. Segregation and bleeding can occur if heavier particles separate from the paste or water rises to the surface, and are reduced by proper mix design and placement. Compaction is important to remove air bubbles while the concrete is still plastic.
Quality control of concrete
This document discusses quality control of concrete through various tests on fresh and hardened concrete. It begins with an introduction to concrete and quality, then discusses where quality control begins in the production of materials and continues through handling, batching, mixing, transporting and placing concrete. Key tests on fresh concrete include slump and compacting factor tests, while tests on hardened concrete include compression, tensile strength, and flexural strength tests to evaluate the quality and strength of the concrete. The document also reviews materials used in concrete such as cement, water, aggregates, and admixtures.
Properties of concrete
Concrete is a versatile building material that is strong, durable, and resistant to fire and corrosion. It is made by mixing cement, aggregates like sand and gravel, and water. As the cement hydrates, it hardens and binds the aggregates together. The document discusses the properties of concrete's constituent materials and how they affect the properties of hardened concrete, such as strength, permeability, thermal properties, and cracking. It also covers quality assurance measures like quality control plans, testing, and audits to ensure high quality concrete construction.

Cement testing
- 2. About Cement Testing • Chemical analysis of hardened concrete can provide a wealth of information about the mix constituents and possible causes of deterioration. • Standard methods can be used to find the cement content and original water/cement ratio, but many other properties can also be established; Cement Content and Aggregate Cement Ratio, Cement Content and Pulverised fuel ash/fly ash (pfa) content, Cement Content and Slag content, Water/Cement Ratio, Aggregate Grading, Determination of the presence of High-Alumina Cement (HAC).
- 3. • Compressive strength: The most common strength test, compressive strength, is carried out on a 50 mm (2-inch) cement mortar test specimen. The test specimen is subjected to a compressive load (usually from a hydraulic machine) until failure. • Fineness: The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Greater fineness increases the surface available for hydration, causing greater early strength and more rapid generation of heat. Cement fineness play a major role in controlling concrete properties. Fineness of cement affects the place ability, workability, and water content of a concrete mixture much like the amount of cement used in concrete does.
