Abstract

Ceramisite concrete is characterized by lightness, good thermal insulation as well as durability. In response to the needs of the roofing construction of a training center, the influence of factors like ceramisite pretreatment, dosage of viscosity modifier and retarder on the working performance and mechanical properties of pumping ceramisite concrete is studied. An appropriate proportion of concrete mix is observed to meet the construction needs and applied to the roofing construction. The result provides experimental data and serves as references for the design and application of pumping ceramisite concrete in roofing construction.

Keywords
