Abstract:
Cementitious compositions exhibiting accelerated hardening including improved strength development are formed by the addition of from about 0. 5% to about 10% formic acid based on the weight of the cement. Compositions exhibiting accelerated setting as well as accelerated hardening may also be formed. The resulting strengths are superior to those exhibited by compositions using formate salts.
