A high-performance concrete mix design lab in Udaipur supplies initial mix proportions that need to be more or less modified to meet the desired concrete properties. A concrete mix is a combination of five major elements in various proportions: cement, water, coarse aggregates, fine aggregates (i.e. sand), and air. Additional elements such as pozzolanic materials and chemical admixtures can also be incorporated into the mix to give it certain desirable properties.
