WebDec 1, 2015 · Expression for optimum water content for making workable cement mortar is presented. ... Strength = K 1 K 2 w c where K 1 and K 2 are constants, w is mass of water and c is mass of cement. This formula is valid over the range of w/c ratio of 0.3–1.20. Abrams’ law is well known for relation of strength and w/c ratio of the concrete. WebIt is represented by To obtain relationship between the moisture content and dry density, multiply the numerator and denominator of expression of dry density with “M” which is mass of soil sample. Mass of the soil (M) is nothing but the addition of Mass of solids (Ms) and Mass of water (Mw).
WebJul 17, 2024 · Water content plays a very important role in soil compaction. The maximum dry density is only achieved when the water content is at an ideal level. This point is known as optimum moisture content or OMC. Optimal moisture content and maximum dry density are determined in a laboratory and are then used as targets for on-site operations ...
