VRUSHALI DESHMUKH answered • 2 hours agoLower the shrinkage limit greater is the volume change.
For coarse grained soil with fines < 5% classification will be GP, GW, SP, and SW, for fines > 12% classification will be based on plasticity chart as GM, GC, SM and SC. For fines 5 -12% dual classification like GP - GM; GP - GC etc., will be used.
At liquid limit the soils possess a certain shear strength which is the smallest value that can be measured in a standard procedure. From direct shear tests on different types of clays it is found that liquid limit corresponds to a shearing strength of about 2.7 kN/m2.
If shrinkage limit Is less the volume change with change in water content will be more.

Shanti Kumari answered • 13 hours agoAdmixtures are the chemical compounds in concrete other than hydraulic cement (OPC), water, aggregates and mineral additives that are added to the concrete mix immediately before or during mixing, to modify one or more of the specific properties of concrete in the fresh or hardened state. In normal used, admixture dosages are less than five percent by mass of cement. Some of the important admixtures and purposes for which they could be used are: Accelerators: They-speed up the initial set of concrete, i.e., rate of development of strength at early ages. Typical materials used are CaCl2 and Retarders: The slow down the initial set of concrete, i.e., keep the concrete workable for a longer time for placement. These are generally used in large or difficult placement conditions where partial setting before the placement is complete is undesirable.
