Abstract
Macro defect free cementitious products are obtained by curing or firing a cementitious composition comprising water, a reactive filler and a water soluble alkali metal silicate. The products show good strength and heat and water stability, by contrast with known mdf products where leaching out of the polymers used results in decreased strength.
