摘要
实验对比研究了标准养护、热水养护 ( 90℃ )和高温养护 ( 2 0 0℃ )三种养护制度以及热养护后的静置室内( 2 0℃ )和浸入水中 ( 2 0℃ )两种处理对RPC混凝土和不掺或单掺硅灰或石英粉掺合料的混凝土强度的影响。研究发现热养护有利于提高混凝土的抗压强度 ,获得高强、超高强混凝土 ;然而 ,混凝土热养护后静置室内或浸入水中 ,观察到强度有倒缩现象。
The effects of three types of curing schedule such as standard curing,heat water curing(90℃) and high temperature curing(200℃)and two kinds of treatment following heat curing on the RPC strength compared to the concrete which was blended silica fume or crushed powder or not were studied.It was demonstrated that heat treatment on the concrete was beneficial to the compressive strength.Nevertheless,the compressive strength was decreased after the concrete was immersed water (20℃) or put in the chamber(20℃) following heat curing. 〔
