Q: What is importance of Atterberg Limits Test on construction?
A: Atterberg Limit Test is used to determine water content of soil. Water Content of the soil has big influence on strength of soil. Depending on water content of soil, the soil can be categorized in four different states (solid, semi-solid, plastic and liquid). With the help of Atterberg Limit test, soil type can be determined and it guides if soil requires treatment before construction, and what type of foundation is suitable for construction.
Q: What is unconfined compressive test?
A: Unconfined Compressive Test (UCT) is fastest method to find the compressive strength of cohesive soil without applying any lateral confinement pressure. This test is not suitable for dry sands or crumbly clays as materials would fall apart in absence of lateral confinement.
Q: What is consolidation test of soil?
A: Under static sustained load, the volume of saturated soil changes due to expulsion of water, which leads to settlement of soil. The consolidation test of soils are required to estimate the magnitude and the rate of possible settlement.
