    CBR test is done in construction materials laboratories to evaluate the strength of soil subgrades and base course materials. The purpose of soil sample soaked in water for 7days is to find out the strength of the sample after soaking continuously in water. The effective CBR should be 75% .

    Strap Footing :- Strap footing is necessitated when a certain column footing has to be restricted in width due to unavoidable interference or boundary limitation. Basically, it is a type of combined footing, consisting of one additional, or more full width column footings connected by a concrete beam.

    Dry shrinkage or drying shrinkage occurs due to loss of moisture in the concrete. There are different types of water in a hydrated cement paste. Dry shrinkage occurs due to the loss of capillary water. This water can be found in voids of sizes ranging from 5 nm to 50 nm in the hydrated cement paste.Read more

    Dry shrinkage or drying shrinkage occurs due to loss of moisture in the concrete. There are different types of water in a hydrated cement paste. Dry shrinkage occurs due to the loss of capillary water.

    This water can be found in voids of sizes ranging from 5 nm to 50 nm in the hydrated cement paste. Due to the small size of the voids, the water is held inside by surface tension or capillary tension. Due to the bond created by the surface tension, evaporation, or any other form of removal of this water causes significant volume changes to the structure. This volume changes causes dry shrinkage to the structure.

     

    Thanks!

    If a building foundation sits on soft or filled-in soil, the whole building may fail in an earthquake regardless of the advanced engineering techniques employed. Assuming, however that the soil beneath a structure is firm and solid, engineers can greatly improve how the building foundation system will respond to seismic waves.

    Another solution refers to base isolation which involves floating a building above its foundation on a system of bearings, springs or padded cylinders.
