High-ductility cement-based composite material
The invention discloses a high-ductility cement-based composite material, and relates to the technical field of cement-based composite materials. The composite material comprises the following components: Portland cement, fly ash, quartz sand, polyvinyl alcohol fibers, water, a polycarboxylic acid type water reducing agent, super absorbent resin and light calcined magnesia, and the Portland cement and fly ash form a cementing material; the composite material comprises the following components in parts by mass: 1.00 part of Portland cement, 3.00 parts of fly ash, 0.02 part of water reducing agent, 0.016 part of super absorbent resin and 0.24 part of light calcined magnesia, wherein the water-binder ratio is 0.30, and the sand-binder ratio is 0.36; and by volume ratio, the polyvinyl alcohol fibers account for 0.02% of the total volume of the high-ductility cement-based composite material. The invention provides the high-ductility cement-based composite material, and the high-ductility cement-based composite material can quickly realize self-repairing in a natural environment, and has a self-healing mode which is higher in searching speed and better in effect.
一种高延性水泥基复合材料，涉及水泥基复合材料技术领域，包括以下组分：硅酸盐水泥、粉煤灰、石英砂、聚乙烯醇纤维、水、聚羧酸型减水剂、高吸水树脂和轻烧氧化镁，所述的硅酸盐水泥和粉煤灰构成胶凝材料；各组分的配合比设计为：按质量比：硅酸盐水泥1.00，粉煤灰3.00，减水剂0.02，高吸水树脂0.016，轻烧氧化镁0.24，水胶比0.30，石英砂的砂胶比0.36；按体积比：聚乙烯醇纤维占高延性水泥基复合材料总体积的0.02。本发明提供了一种高延性水泥基复合材料，该高延性水泥基复合材料在自然环境中可以快速实现自我修复，具有寻找速度更快，效果更优的自愈合方式。
