Building Material testing
Properties of Construction Material change from place to place. Sometimes, they may affect the strength and durability of the Structure, based on their Engineering Properties like Specific Gravity, Flakiness, Grain size, Elongation, etc. of aggregates. However, the Compressive Strength of Cement also gets reduced on its defective storage for large durations in godowns before it is used at the site. Hence, it is required to confirm the physical properties of Cement well in advance before its usage in Construction Work. Another reason by virtue of which the Compressive Strength and Durability of Concrete quite often gets reduced is due to excess/less quantity of water Cement ratio used in its preparation. Whereas, the presence of soluble salts in Water used in Construction Work may also damage the Building after certain lapse of Construction Time. Therefore, it is necessary to check/test the materials being used in construction for their inherent properties before starting the Construction Work as per various relevant IS standards.
Hence, the need arise for proper Quality Control Tests like Cement Concrete Mix Design, etc. being done for various Civil Engineering Structures for their Safe Design.
