Abstract:
A two part hardenable silicate material having a first part being a substantially water-free hardener composition, said hardener composition comprising:(a) from 10% to 60% of an organic carbonate hardener for the silicate (b) from 20% to 85% of a cement hardenable by reaction with water and (c) from 0.05% to 10% of a retarder for the cement, the % being by weight based on the total weight of (a), (b) and (c) and the material having a second part being a silicate-containing composition comprising,(i) from 40% to 85% of a filler (ii) from 3% to 40% of an alkali metal silicate and (iii) from 5% to 70% of water, wherein the percentages being by weight based on the total weight of (i), (ii) and (iii) and the amount of silicate being on a dry basis and wherein the relative amounts of the reactants are such that when the parts are mixed, the reactants will form a hardened mass.
