High-crack-resistance cement-based composite material and preparation method thereof
The invention discloses a high-crack-resistance cement-based composite material and a preparation method thereof, and solves the problems that a traditional cement-based material is poor in crack resistance, low in tensile strength and insufficient in toughness performance. The material comprises a cementing material component and a carbon fiber woven mesh; the cementing material component comprises self-stress sulphoaluminate cement, medium sand, fine stone, water, chopped polyvinyl alcohol (PVA) fibers, styrene-butadiene emulsion and a Sika third-generation polycarboxylic super plasticizer; the mass ratio of the self-stress sulphoaluminate cement to the medium sand to the fine stone to the water to the chopped polyvinyl alcohol PVA fiber to the styrene-butadiene emulsion to the Sika third-generation polycarboxylic acid super plasticizer is 1: 1.2: 0.8: 0.36: (0.15%-0.225%): (5.3%-6.8%): 0.13%; the carbon fiber woven mesh is made of mesh cloth which is woven by carbon fibers with the content of 1600TEX and has the size of 20mm * 20mm. The invention further provides a preparation method of the high-crack-resistance cement-based composite material.
本发明公开了高抗裂性能水泥基复合材料及其制备方法，改善了传统的水泥基材料抗裂性能差、抗拉强度低且韧性性能不足的问题，该材料包括胶凝材料组分和碳纤维编织网；胶凝材料组分包括自应力硫铝酸盐水泥、中砂、细石、水、短切聚乙烯醇PVA纤维、丁苯乳液与Sika第三代聚羧酸系超塑化剂；自应力硫铝酸盐水泥与中砂、细石、水、短切聚乙烯醇PVA纤维、丁苯乳液与Sika第三代聚羧酸系超塑化剂的质量比为1:1.2:0.8:0.36:(0.15％～0.225％):(5.3％～6.8％):0.13％；碳纤维编织网选用1600TEX含量碳纤维编织成20mm×20mm尺寸的网格布；还提供了高抗裂性能水泥基复合材料的制备方法。
