Abstract
An admixed and kneaded material of a mixture of a hydraulic powder, a potentially hydraulic powder, water, and fine and coarse aggregates, if necessary is molded and hardened. Then the hardened body is heat cured to form silicic acid anions of at least a trimer. This molded and hardened body has a compression strength at least 1000 kgf/cm.sup.2 and a bending strength of at least 150 kgf/cm.sup.2 so that hardened cement body having a high mechanical strength can be obtained without using a special reinforcing member or fiber. The hardened concrete product of this invention has a high bending strength, compression strength and modulus of elasticity. A glaze can be applied and fired to obtain beautiful concrete products.
