WHICH TYPES OF CONCRETE ARE USED IN DIFFERENT STRUCTURE?

 B15 The different types of Concrete generally used in typical Construction of structures are as follows: Sulphate Resisting Concrete (SRC)/ Plain Cement Concrete (PCC) – Used for non-structural works such as Blinding, Screeding, and Protection works. Generally, this is low strength concrete with a mixed design of M15 or M20. Microsilica Concrete – Typically used for Substructure Construction. Microsilica Concrete is generally preferred for elements in contact with soil or water. This type of Concrete is preferred in Rafts, Basement Slabs, Piles and Pile Caps, Retaining walls, etc. High Strength Concrete – This type of concrete does not have any special additive but is designed for load-bearing elements such as Columns, Shear walls, transfer beams, etc. Mix designs may vary from M45 to M70 based on strength requirements. Waterproof Concrete – In this type of concrete, a waterproof admixture is added to concrete during batching to impart waterproofing properties in concrete. This ty...

WHICH CEMENT IS USED IN UNDERWATER CONCRETE?

 B16 Underwater concrete contains three ingredients: sand or gravel, water, and cement to hold it all together. The type of cement used for most construction, including underwater construction, is Portland cement. Made from heated clay and lime, Portland cement is the secret to concrete’s ability to set underwater. The Roman invented underwater cement and one can still see the concrete that was manufactured two thousand plus years ago. We should use  Portland-pozzolana cement (PPC)  for any type of underground construction works. During the construction of bridges, dams, or any structure where the foundation is most likely to lie underwater, the underwater construction has opted. During underwater Construction, the main objective is to create a dry and water-free environment for working so that the stability of the structure is balanced. Cement- Weight of 1 kg cement bag – 50 kg. The volume of 1 kg cement bag – 0.035 cum. m Weight of 1 cum. m of cement – 1440 kg or 28.80 ...

HOW TO CHECK QUALITY OF BRICKS ON-SITE?

 B19 Bricks are the building blocks of a building. If the quality of brick used in a structure is not good then it can lead to serious damages to the building. Therefore it is necessary to check the quality of brick before using it in any construction activities. There are some field tests that we can conduct in the field in order to check the quality of bricks. These tests are as follows. Clap Test Drop Test Shape and Size Test Water Absorption Test Efflorescence  Color Test Hardness Structure Examine frog in Brick Here are some simple yet effective brick tests you can take to check the quality of bricks, 1- Clap Test: If you clap two bricks together, they should make a metallic, clear ringing sound. This test helps you determine the reaction of bricks against sudden impact. 2- Drop Test: Drop a brick from a 4 feet height, if it does not break then the brick is of good quality. If the bricks are broken it indicates low impact value and is therefore not good for construction. ...
