Description

一种高效能混凝土
技术领域
本发明涉及建筑材料领域的水泥基复合材料,具体地说是一种改善水泥浆体孔隙结构及匀质性的高效能混凝土。
背景技术
工程裂缝已成为施工中的焦点问题,其中大体积混凝土的裂缝问题尤其受到关注。影响混凝土抗裂性的因素分为内部因素与外部因素。对于尺寸较大的平板厚型大体积混凝土(一般厚度超过1m,尺寸在100m左右,以下简称大面积底板混凝土)而言,影响其抗裂性的重要因素为混凝土的自身性能和地基约束力。大面积底板混凝土结构由于厚度较厚,水化反应过程中易形成内外温差,产生温度应力,尤其是其受到地基及内部钢筋约束较大,极易形成较大的收缩应力而开裂,对混凝土的抗裂性要求非常高。
