摘要
A method is described for making concrete from an initially dry mixture including Portland cement, a fine aggregate, and a coarse aggregate. The method is effective for curing mixtures which contain rubble, as well as for mixtures which contain primarily virgin aggregate. In the method, substantially dry steam is introduced to the mixture at elevated temperature and pressure. Air injection may be utilized to further increase the pressure. An improved concrete is also described. The concrete exhibits unexpectedly high compressive strength.
