摘要
废弃水泥混凝土再生集料在配制混凝土或采用无机结合料稳定做基层材料时 ,存在明显的需水量改变的问题。通过试验和分析认为 ,需水量的改变一是再生集料配制混凝土时要额外吸收一定的水分 。
When regenerated aggregate of scrap concrete are used as a material in cement concrete mixture or in semirigid base course stabilized by cement, some changes about the moisture content required are presented remarkably. According to experiment and analysis, it is considered that one reason to cause the changes is that regenerated aggregate can absorb some water from concrete mixture, and the other reason is that the crystal water existed in regenerated aggregate adds up to the optimum moisture content of semirigid base course materials.
