Abstract

Rapid-setting cementitious compositions comprise hydraulic cement and at least 4% by weight based on the weight of the cement of a water-soluble citrate, malate or citramalate or a mixture thereof. Alkali metal citrates, malates and citramalates are preferred. The compositions are especially useful as shotcrete.
