Total paste volume of concrete consists of the void between aggregates(V_V) and the lubricating paste for workability i.e.the surface area of aggregates(S) multiplied by coating thickness(t).So the total paste volume of concrete can be described as V_P=V_V+St.This study presents a new approach to design concrete mix proportions by coating thickness of aggregates.This approach is on the basis of densified mixture design algorithm(DMDA) and adopts the Fuller's curve to deduce a new method to design concrete m...
