Low-carbon low-shrinkage engineering cement-based composite material and preparation method thereof
The invention provides a low-carbon low-shrinkage engineering cement-based composite material and a preparation method thereof, and relates to the technical field of engineering cement-based materials, and the low-carbon low-shrinkage engineering cement-based composite material is mainly prepared from the following raw materials in parts by weight: 240-360 parts of ordinary Portland cement, 560-650 parts of calcined clay and 280-320 parts of limestone powder. The calcined clay and the limestone powder are used for replacing a large amount of cement, the use amount of the Portland cement is remarkably reduced, the environmental protection benefit is remarkable, the mechanical property of the cement-based composite material is improved by doping the calcined clay and the limestone powder, and the calcium sulfate whiskers are introduced into the composite material. On one hand, sulfate is used for adjusting the hydration reaction of a cement matrix, and on the other hand, multi-scale fibers are mixed, so that the composite material can be reinforced on different scales, the toughness and strength of the cement-based composite material can be greatly improved, and greater possibility is provided for popularization and application of the cement-based composite material.
本发明提供一种低碳低收缩型工程水泥基复合材料及其制备方法，涉及工程水泥基材料技术领域，该一种低碳低收缩型工程水泥基复合材料，主要成分由以下重量份比例的原料制成：普通硅酸盐水泥240～360份，煅烧粘土560～650份，石灰石粉280～320份，将煅烧粘土和石灰石粉用来大量的替代水泥，实现了硅酸盐水泥用量的显著减少，环保效益显著，且将煅烧粘土和石灰石粉掺入有利于水泥基复合材料力学性能的提升，将硫酸钙晶须引入复合材料之中，一方面利用硫酸盐来调节水泥基体的水化反应，另一方面，多尺度的纤维混杂，可以在不同尺度上对复合材料进行增强，能够大幅度提高水泥基复合材料的韧性和强度，为水泥基复合材料的推广应用提供了更大的可能。
