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.
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.
TESTING OF CEMENT IN LABORATORY
In the laboratory, the testing of cement is done to check the quality of cement for properties, fineness, soundness, consistency, setting time, strength etc.
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

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.

Consistency test,Initial & Final setting time of Hydraulic Cement specimen
Consistency test,Initial & Final setting time of Hydraulic Cement Specimen.
Prepared By=Sheryar Bismil
Compression strength test
Compressive strength of cement is determined by compressive strength test on mortar cubes compacted by means of a standard vibration machine. Standard sand (IS:650) is used for the preparation of cement mortar. The specimen is in the form of cubes 70.6mm*70.6mm*70.6mm.
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.
Setting time test
This document describes a test performed to determine the setting time of hydraulic cement using a Vicat needle apparatus. The initial setting time is defined as the time when the needle cannot penetrate more than 25mm into the cement paste. The final setting time is when the 5mm needle leaves no visible impression. The test involves mixing cement and water, then taking penetration measurements with the needles over time. The initial setting time for the sample tested was calculated to be 82.5 minutes, which meets the Iraqi specification of no less than 45 minutes.
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.
Testing of cement
The document summarizes various tests conducted on cement, including:
1. Field testing to check for lumps, color, texture and consistency.
2. Standard consistency tests to determine the percentage of water required for a cement paste.
3. Fineness tests using sieving or air permeability methods to check particle size.
4. Soundness tests using a Le Chatelier apparatus to ensure cement does not expand after setting.
5. Strength tests involving casting cement-sand mortar cubes and breaking them to measure compressive strength after curing.
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 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.
Manual plastering
Plaster is a building material used to coat and protect walls and ceilings. It involves mixing cement, sand, water and fibers to create a mortar that is applied to surfaces. The manual plastering process includes preparing scaffolding and mixing mortar on-site, applying chicken mesh to joints, using level pads as guides for uniform thickness, smoothing and finishing the plaster coat. Challenges include lack of proper supervision, quality control issues like inconsistent water-cement ratios, and inefficient work practices.

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.
Time&temperature of processing eva film laminated glass
The document provides guidelines for processing EVA film laminated glass at different temperatures and times based on the thickness of the glass. It recommends heating glass to 70°C for 10-20 minutes, then 130°C or 110°C for 30-60 minutes depending on thickness, before allowing it to cool below 75°C and finish vacuuming for less than 40°C. Additional tips note to vacuum for longer for multi-bed ovens and to adjust times for tempered glass.
Normal consistency test
This document describes a test conducted to determine the normal consistency of a hydraulic cement. The objective is to find the amount of water needed to create a cement paste of a certain standard thickness. The test procedure involves mixing cement with varying amounts of water and using a Vicat apparatus to measure when a plunger settles 10±1mm below the original surface of the paste within 30 seconds. The percentage of water that produces a paste with this consistency is considered the normal consistency and is used to standardize mixtures for other cement tests.

Frank L. Wright : Falling waters and key projects
1. Fallingwater or Kaufmann Residence is Frank Lloyd Wright's house built in 1935 over a waterfall in rural Pennsylvania.
2. Wright designed the house with horizontal and vertical lines and spaces that bring the natural surroundings inside. Notable features include cantilevered balconies and a staircase leading to the waterfall.
3. The house uses local stone and wood in its intrinsic construction, with furnishings in a triadic color scheme and monochromatic brown walls, ceilings and floors. However, the bold concrete design experienced deflection issues from the beginning.

A SYSTEMATIC RISK ASSESSMENT APPROACH FOR SECURING THE SMART IRRIGATION SYSTEMS
The smart irrigation system represents an innovative approach to optimize water usage in agricultural and landscaping practices. The integration of cutting-edge technologies, including sensors, actuators, and data analysis, empowers this system to provide accurate monitoring and control of irrigation processes by leveraging real-time environmental conditions. The main objective of a smart irrigation system is to optimize water efficiency, minimize expenses, and foster the adoption of sustainable water management methods. This paper conducts a systematic risk assessment by exploring the key components/assets and their functionalities in the smart irrigation system. The crucial role of sensors in gathering data on soil moisture, weather patterns, and plant well-being is emphasized in this system. These sensors enable intelligent decision-making in irrigation scheduling and water distribution, leading to enhanced water efficiency and sustainable water management practices. Actuators enable automated control of irrigation devices, ensuring precise and targeted water delivery to plants. Additionally, the paper addresses the potential threat and vulnerabilities associated with smart irrigation systems. It discusses limitations of the system, such as power constraints and computational capabilities, and calculates the potential security risks. The paper suggests possible risk treatment methods for effective secure system operation. In conclusion, the paper emphasizes the significant benefits of implementing smart irrigation systems, including improved water conservation, increased crop yield, and reduced environmental impact. Additionally, based on the security analysis conducted, the paper recommends the implementation of countermeasures and security approaches to address vulnerabilities and ensure the integrity and reliability of the system. By incorporating these measures, smart irrigation technology can revolutionize water management practices in agriculture, promoting sustainability, resource efficiency, and safeguarding against potential security threats.
Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
