开发利用石屑与特细砂配制砼

    Development and Use of Attles and Special Fine Sand in Making up Concrete

    • 摘要: 豫西的石屑和开封的特细砂混合配制检,该检具有强度高、流动性好、利于泵送、抗渗、抗冻性能好。价格低廉、易于就地取材,可使异地材料性能差异得到互补等显著优点。充分利用地域材料配制性能良好的检,是当前乃至今后工程项目降本节支的主要途径之一,开发利用石屑与特钢砂配制检很有价值。

       

      Abstract: The attles in the west part of Henan province and the special fine sand in Kaifeng are mixed to make up concrete, which possesses the outstanding characteristics of high sbength, good flowability, easy of bump delivery, high impermeability and high antifreeze, fow price, as well as the local available materials. This gnd perfonnance concrete, which can make up the vallous prosperity of vallous places, is one of the important ways of reducing product costs and cutting down the expense of the works at pasent or even in the future. As a result, it is worth well devefoping and using this kind of concrete.
