Get PPT here https://civilinsider.com/compressive-strength-test-on-cement/ 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.

Hydrometer analysis for soil .pptx
Hydrometer analysis is used to determine the particle size distribution of fine-grained soils like silt and clay. It involves measuring the settling rate of soil particles in water over time using a hydrometer, which applies Stokes' law. Larger particles settle faster than smaller ones. The sedimentation cylinder contains the soil sample mixed with a dispersing agent in water. Hydrometer readings over time from 15 seconds to 24 hours indicate the percentage of soil finer than various sizes based on their settling depths. Calculations using the hydrometer reading, temperature, specific gravities of soil and water determine the particle size distribution by weight.

This document provides an overview of sedimentary rocks and the processes involved in their formation. Sedimentary rocks are formed from the deposition of materials at the Earth's surface or within bodies of water. They provide information about past environmental conditions and geological history. The key processes involved in sedimentary rock formation are weathering, erosion, transportation, deposition, and diagenesis, which is the chemical and physical changes that occur after deposition. Sedimentary rocks can be divided into clastic sediments like sandstone, chemical sediments like limestone formed by precipitation from solution, and biochemical sediments like coal formed from organic material.
Vishnu clastic rock ppt
Clastic sedimentary rocks are classified based on grain size into conglomerate, sandstone, siltstone, shale and mudstone.
Conglomerates contain rounded gravel size clasts (>2mm) in a finer matrix. They form from erosion of other rocks. Sandstones contain quartz and feldspar grains between 0.06-2mm. Shales and mudstones have the finest grains (<0.06mm) composed of clay minerals and quartz silt. Shales are fissile while mudstones are non-fissile. Clastic rocks form from weathering and erosion of older rocks transported by rivers, glaciers, wind or ocean currents.

https://civilinsider.com/difference-between-one-way-slab-and-two-way-slab/
What is a Slab?
Slabs are the one of the most widely used structural elements whose depth is considerably smaller than rest of the dimensions. Basically slabs are used as roofs and floors in buildings, roof and bottom on water tanks, on bridges etc.
Slabs support and transfer load i.e. Dead load and live load, to columns by shear, flexure, and torsion. Slabs also help in reducing the effects of lateral wind loads and earthquake loads.
What is One Way Slab?
One way slabs are the slabs in which most of the loads are carried on the shorter span. The ratio of longer span to shorter span is equal to or greater than two or when the slab is supported by beams only along two opposite sides slab then the slab behaves as a One-way slab.
What is Two Way Slab?
Two-way slabs are the slabs in which loads are carried on both of the spans. The ratio of longer span to shorter span is less than two and when the slab is supported by beams along all the sides then the slab behaves as a two-way slab.

What is Working Stress Method of Design?
In the working stress design method for Reinforced Concrete Structures design, concrete is assumed as elastic also concrete and steel act together as a single unit elastically i.e relationship between stress and strain is linear.
WSM and LSM steel structures
Get PPT here
What is the WSM method?
In the working stress method, the stress-strain curve is assumed to be linear to the yield stress. To overcome the problems and damages due to uncertainty in design, permissible stress is kept as a fraction of the yield stress. As factor of safety is the ratio of yield stress to working stress, the members of the structure are sized to keep stresses within the permissible value.
The working stress method is the oldest systematic analytical design method. Although IS 800-2007 gives more details and preferences to limit state method, it also permits the use of the working stress method wherever the limit state method is not practically adaptable.
In Limit State Method, structure should be able to carry and withstand all the loads which will act on it throughout its life. Structure should not suffer total collapse under any kind of accidental loads such as explosions.

https://civilinsider.com/field-tests-on-cement/
Construction materials testing is a process that helps engineers, contractors, and owners to list out problems and deficiencies in materials before actual construction. Field testing help to find out whether the materials are suitable for construction or not by just simple visual and easy practical tests.
Why to Test Cement on Site?
Testing of Cement on the site is done using some quality tests to get an overview of cement in a short period of time. It’s impossible to carry out Laboratory tests in a short period of time and for a small or medium-scale work so some field tests are carried out to check the quality of cement. These tests give an overview of the quality of cement.

https://civilinsider.com/initial-and-final-setting-time-of-cement/
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?
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.

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.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

- 4. Compressive Strength Definition Compressive Strength of any material or structure is the ability to carry the load on its surface without cracking or bending. The compressive strength of a material or structure gives an idea about the load- carrying capacity of that material or structure. BYWWW.CIVILINSIDER.COM
- 5. What is Compressive Strength Test? Compressive strength test is a method used to find out the resistance of any material or structure and ability of that structure or material to recover after the application of Compressive force on the surface for a defined period of time. In the Compressive Strength test we apply a push force on both the faces of specimen and the maximum force the specimen bears without failure is noted down and that is the Compressive strength of that Cement. BYWWW.CIVILINSIDER.COM
- 6. Compressive Strength Formula Compressive strength is calculated as the ratio of the maximum load carried by specimen to the exposed surface area of specimen. The formula for Compressive strength is F=P/A where F is Compressive strength in (MPA), P is load applied in (N) and A is surface area in (sq m).

Molding of Specimen: 2) Immediately after mixing of the mortar, place the mortar in the cube mould and prod with the help of the rod. The mortar shall be prodded 20 times in about 8 sec to ensure the elimination of entrained air. 3) If the vibrator is used, the period of vibration shall be 2 minutes at the specified speed of 12000 ± 400 vibrations/minute. Then place the cube moulds in temperature of 27±2 °C and 90% relative humidity. 4) After completion of vibration remove the mould from vibrator and level the surface by trowel or blade.
- 12. PROCEDURE 1) After completion of compaction place the specimen in a moist closed room for 24 hrs. Then remove the mould and immediately put the block into the water until removals for the tests. Curing of Specimen: 2) The water in which these cubes are placed shall be changed in 7 days and should be at room temperature. 3) During changing of water the cubes are not allowed to dry And should be removed for Compressive Strength Test in 7, 14, and 28 days. 4) During testing, the load shall be applied uniformly from 0 at a rate of 35 N/mm² per minute.
- 13. 1) Test the specimen on a 7 day period. 2) The temperature should be 27±2 °C and relative humidity 90%. Precautions:
