<p>PURPOSE:To obtain high-strength, heat-resistant concrete capable of being produced easily controllably, relatively readily and inexpensively, having excellent heat resistance and the same water/cement ratio as that of ordinary concrete free from rupture in heating. CONSTITUTION:A ground material of waste articles and nonstandard articles of ceramic-based materials such as ceramic and porcelain having strength of >=1,000 [kfg/cm<2>] compressive strength or >=200 [kgf/cm<2>] flexural strength and >=1,000 [ deg.C] temperature history is used an aggregate and mixed with ordinary Portland-based material in the ordinary ratio of water/cement, selectively blended with another aggregate such as natural aggregate and an addition agent and molded.</p> |
