Nano-modified high-fluidity vitrified microbead thermal insulation mortar
The invention discloses nano-modified high-fluidity vitrified microbead thermal insulation mortar and a preparation method thereof, and the mortar is prepared from the following components in parts by weight: 60.4 parts of cement, 19.4 parts of fly ash, 20.2 parts of slag, 263-701 parts of vitrified microbeads, 2 parts of latex powder, 0-3 parts of a nano material, 1.24-4.2 parts of an additive and 50-179.7 parts of water. Wherein the nano material comprises nano silicon dioxide and/or nano calcium carbonate. On the basis of conventional proportion optimization, the performance of the glass bead thermal insulation mortar with various strength grades is further improved through a thermal insulation modification measure of doping a lauryl sodium sulfate air entraining agent and a nano modification measure of doping nano SiO2 and nano CaCO3, and the performance improvement mechanism of the glass bead thermal insulation mortar is analyzed in combination with microanalysis.
本发明公开了一种纳米改性高流动度玻化微珠保温砂浆及其制备方法，该砂浆按照重量份数计算，其由60.4份水泥、19.4份粉煤灰、20.2份矿渣、263‑701份玻化微珠、2份乳胶粉、0‑3份纳米材料、1.24‑4.2份外加剂和50‑179.7份水制成；其中，所述纳米材料包括纳米二氧化硅和/或纳米碳酸钙。本发明在常规的配比优化基础之上，通过掺入十二烷基硫酸钠引气剂的保温改性措施和掺入纳米SiO2和纳米CaCO3的纳米改性措施进一步提升多种强度等级的玻化微珠保温砂浆性能，并结合微观分析其性能提升机理。
