泵送玻化微珠保温混凝土的抗离析和抗泌水性能试验研究

Experimental Research on Segregation Resistance and Bleeding Resistance of Pumping Glazed Hollow Bead Insulation Concrete

为了减少玻化微珠保温混凝土在泵送施工过程中出现的离析和泌水现象,进行了玻化微珠保温混凝土分层度试验和压力泌水试验;通过对原材料的控制以及外加剂的选择,提高了玻化微珠保温混凝土的可泵性,并将其应用于的现场施工,收到了良好的效果。

In order to reduce the segregation and bleeding phenomenon of the glazed hollow bead insulation concrete in the pumping construction process, the corresponding solution by the stratification test and pressure bleeding test on glazed hollow bead insulation concrete are put forward. The pumping ability of glazed hollow bead insulation concrete is improved by the control of raw materials and selection of additives. In the construction site, it is proved that these measures can receive a good effect.
