泵送粉煤灰-矿碴粉混凝土施工的质量控制——以南水北调中线一期天津干线工程为例

Construction quality control of pumping flyash-slag concrete

在南水北调中线一期天津干线工程中,输水箱涵采用粉煤灰-矿碴粉混凝土,用泵送的方法施工。对原材料的质量、混凝土的配合比、混凝土拌和物的质量、混凝土现场浇筑和养护等实行严格控制,取得了较好的施工质量。

The pipe culvert built in Tianjin diversion canal of the Sout-to-North Water Diversion Middle Route Project is made of reinforced flyash-slag concrete.The concrete is transferred by pumping in construction.The selection of raw materials,concrete mix proportion,concrete pouring and curing on-site are strictly controlled to achieve fine quality.
