Concrete viscosity modification material and preparation method thereof
The invention discloses a concrete viscosity modified material and a preparation method thereof, and belongs to the technical field of building materials. The concrete viscosity modifying material comprises the following components in percentage by mass: 65%-85% of a mineral admixture, 15%-35% of a modified tackifier, 1%-5% of an inorganic thixotropic agent and 1%-5% of an organic thixotropic agent, wherein the modified tackifier is obtained by taking rice hull ash obtained by calcining rice hulls, pretreated biogel and a silane coupling agent as raw materials, and performing dispersion, standing and spray drying. The modified tackifier is prepared from the rice hull ash, the biological glue and the silane coupling agent, then the mineral admixture, the inorganic thixotropic agent and the organic thixotropic agent which have high-quality thixotropic performance are compounded, the finally prepared concrete viscosity modified material has excellent thixotropy, the working performance of concrete can be improved, and meanwhile, the concrete viscosity is improved. The problems of bleeding, segregation and the like of mortar and concrete are effectively solved, and the application value is high.
本发明公开了一种混凝土粘度改性材料及其制备方法，属于建筑材料技术领域。所述混凝土粘度改性材料包括以下质量百分比的组分：矿物掺合料65%~85%，改性增粘剂15%~35%，无机触变剂1%~5%，有机触变剂1%~5%；其中，所述改性增粘剂是以稻壳煅烧得到的稻壳灰、预处理后的生物胶以及硅烷偶联剂为原料，经分散、静置、喷雾干燥得到。本发明采用稻壳灰与生物胶以及硅烷偶联剂制备改性增粘剂，然后复配具备优质触变性能的矿物掺合料、无机触变剂以及有机触变剂，最终制备的混凝土粘度改性材料具备优异的触变性，能够在提高混凝土工作性能的同时，有效解决砂浆、混凝土的泌水、离析等问题，极具应用价值。
