APPLICATION OF HIGH-PERFORMANCE GLASS FIBER OPTIMIZED CEMENT-BASED COMPOSITE MATERIALS
In order to solve the technical problems of poor consolidation effect,low strength,and easy crack-ing of deep filling materials,a study was conducted by adjusting the glass fiber content and optimizing the proportion of cement-based mixtures,so that composite materials can be applied in building wall structures.The results showed that when the amount of PA66 added was 10wt%,the composite material could exhibit the best fluidity and process-ing performance.In terms of mechanical properties,although the tensile strength and tensile modulus decrease with the increase of PA66 addition,the bending strength shows an increasing trend,indicating that the addition of PA66 has a positive effect on improving the bending performance of composite materials.This structural system has the characteristics of high assembly degree,large safety margin,strong lateral stiffness and lateral bearing capacity.
