摘　　要：针对传统装配式建筑墙体力学性能差的问题,制备一种纳米材料改性钢骨架-粉煤灰陶粒混凝土的轻质节能墙板。以粉煤灰、粉煤灰陶粒、EPS颗粒等作为原材料,采用四因素三水平正交实验的方式首先确定粉煤灰陶粒混凝土的最佳配合比;然后以纳米改性的最佳配比为基础,制备钢骨架-粉煤灰陶粒混凝土墙板;最后分别探讨改性后的粉煤灰陶粒混凝土力学性能和钢骨架-粉煤灰陶粒混凝土的抗压强度。试验结果表明,E4组合配比性能最佳;同时改性后的粉煤灰陶粒混凝土的极限承载力为1418.28kN,单一的粉煤灰陶粒混凝土极限承载力为120.24kN,说明复合墙板抗压强度有较大提升。通过试验,也对轻质墙板的工程应用提供了参考价值。Aiming at the problem of poor mechanical properties of traditional prefabricated building walls,a kind of lightweight energy-saving wall panel with steel skeleton and fly ash ceramsite concrete was prepared.Taking fly ash,fly ash ceramsite and EPS particles as raw materials,the optimal mix proportion of fly ash ceramsite concrete was determined by four factors and three levels orthogonal experiment;then,based on the optimal ratio,steel skeleton was added to the wall panel;finally,the mechanical properties of fly ash ceramsite concrete and the compressive strength of steel skeleton fly ash ceramsite concrete were discussed respectively.The test results show that E4 combination has the best proportioning performance;at the same time,the ultimate bearing capacity of steel skeleton fly ash ceramsite concrete is 1418.28 kN,and the ultimate bearing capacity of single fly ash ceramsite concrete is 120.24 kN,it indicates that the compressive strength of composite wallboard has been greatly improved.Through the test,it also provides a reference value for the engineering application of lightweight wallboard.
