<p>PROBLEM TO BE SOLVED: To solve a problem of a conventional concrete that it ruptures by receiving thermal stress caused by abrupt heating, for example the surface temperature is abruptly raised to 700 deg.C, and to provide a method for producing the rupture resistant concrete. SOLUTION: This rupture resistant concrete is obtained by throwing cellulose fibers into water, and after uniformly dispersing them, cement and aggregate are thrown therein and mixed to obtain the rupture resistant concrete containing cellulose fiber 5 and mainly composed of aggregate 2 dispersed in cement 1. In the concrete of this invention, even when abruptly heated and received thermal stress, the steam pressure generated from internal moisture 3 in the concrete distributes in the arrow mark 6 direction via an escape way formed by e.g. carbonized cellulose fiber 5' so as to prevent the concrete from being ruptured from inside thereof.</p> |
