    摘要:

    对比研究了天然气中砂混凝土和混合砂混凝土的工作性、强度、收缩和徐变性能。研究表明,配合比相同时,混合砂混凝土的性能与细度相当的天然中砂混凝土的性能相当,采用石灰石质机制砂与天然特细砂组成的混合砂可以配制性能良好的大流动性混凝土。

    Abstract:

    In this paper,the workabiltiy,strength.Shrinkage and creep of concrete made from composite fine aggregate (CFC) were studied. Resuits show that the properties of CFC is familiar to those of concrete made from natural middle-size of fine aggregate when the mixture proportion is the same.The composite fine aggregate composed of man-made limestone sand and natural super-fine sand could be used for producing flowing corcrete.
