Zusammenfassung:Disclosed herein is a method for accelerating the curing of a cementitious article, comprising adding a quantity of low bulk density calcium silicate hydrate to a formulation used to produce the article sufficient to accelerate the curing of the cementitious article as compared to an equivalent formulation made without low bulk density calcium silicate hydrate, wherein the bulk density of the low bulk density calcium silicate hydrate is between about 15 Kg/m3 (0.015 g/cm3) and about 1500 Kg/m3 (1.5 g/cm3), and wherein the low bulk density calcium silicate hydrate is added as a powder and comprises from about 0.5% to about 50% by weight of the formulation.
