摘要
A process for preparing fiber-reinforced hydraulic composite material having a high mechanical resistance and durability is characterised by treating the hydraulic binder with compounds in solution (for example, carbonates and bicarbonates of ammonia or of alkaline and alkaline earth metals) at variable concentrations from 0.5 to 20 percent by weight and at different treating temperatures in the range 0 to 99 DEG centigrade. After setting has occurred this reduces the porosity of the product, increases its mechanical resistance, and causes a reduction of alkalinity of the cement matrix which prevents the degradation of the reinforcing fibres.
