摘要
提高混凝土等级节能、节材成为一种发展趋势,而混凝土等级愈高,节约水泥的潜力愈大。从集料最紧密堆积、耐久性和孔结构,水泥石-粗集料高黏接强度诸方面整合其最佳结构模型。进一步通过试验,综合原材料择优、集料级配,"双掺"技术,掺合料强度激发剂,水泥强度富余系数利用等因素,确定实现上述目标的技术路线,以便于工艺过程实施。
It is a kind of developing trend that improving the degree of concrete save resources and cut down material.However the higher of concrete degree, the the bigger of potential saving concrete.From the compactest accumlative permanent stability and hole structure,high adhesive strength of concrete stone and the thick aggregate and so on,we can make the best structure mode.Trough going further experiment,choose the best material aggregate with double-admixtures techology and admixtures strength accelerating-agent.The cement strength factor is utilized,then the executive method of technology is determined in order to realize the craft process.
