Compressive Strength of Concrete Cylinders
The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until ...
Core Sampling and Testing of Concrete and Factors Affecting Strength
Concrete cores are used for testing of actual properties of concrete in existing structures such as strength, permeability, chemical analysis, carbonation etc. Sampling of concrete cores and testing its strength is described. While Rebound Hammer, CAPO/Pullout, Windsor probe and ultrasonic ...
Stripping Value Test On Road Aggregates
What is Stripping Value Test? The stripping value of aggregates is determined as the ratio of the uncovered area observed visually to the total area of aggregates, expressed as a percentage. Bitumen and tar adhere well to all normal types ...
How to Check Cement Quality at Construction Site?
Quality tests on cement at construction site (also called field tests on cement) are carried to check quality of cement supplied for construction use.
Compressive Strength Test on Bricks
Compressive strength test on bricks are carried out to determine the load carrying capacity of bricks under compression with the help of compression testing machine. Bricks are generally used for construction of load bearing masonry walls, columns and footings. These ...
Dry Density of Soil by Core Cutter Method for Soil Compaction
Dry Density of Soil by Core Cutter Method Cylindrical core cutters of 130mm long and 100mm diameter are used for testing the in-situ compaction of cohesive and clay soils placed as fill. By using core cutter method, bulk density of ...
Environment Exposure Conditions of Structures
As per IS 456, an environmental exposure is divided into five parts, i.e. mild, moderate, severe, very severe and extreme. Structures constructed in different conditions have different effects and measures shall be taken to protect the structures under severe to ...
