摘 ? 要:制備了一種以高性能纖維增強水泥基復合材料為殼體、泡沫混凝土為芯體的新型復合墻板,并對其力學性能、熱工性能進行了研究。結果表明:隨著纖維摻量的增加,復合墻板的3 d、7 d和28 d抗折強度明顯增加,7 d和28 d抗折強度均能達到20 MPa以上,極限抗彎荷載系數為9.0;空心墻板的力學性能與復合墻板基本一致;空心墻板的傳熱系數較高,為3.20 W/(m2·K),復合墻板的傳熱系數最低,為0.82 W/(m2·K)。
Abstract: A new type of composite wallboard with high-performance fiber reinforced cement-based composite materials as the shell and foamed concrete as the core was prepared, and its mechanical and thermal properties were studied. The results show that with the increase of fiber content, the 3 d, 7 d and 28 d flexural strength of the composite wallboard obviously increase, and the 7 d and 28 d flexural strength can reach more than 20 MPa, and the ultimate flexural load coefficient is 9.0. The mechanical properties of hollow wallboard and composite wallboard are basically identical. The heat transfer coefficient of hollow wallboard is higher, which is 3.20 W/(m2·K), and the heat transfer coefficient of composite wallboard is the lowest, which is 0.82 W/(m2·K).
