Low-cost high-temperature-resistant self-leveling mortar
The invention discloses a low-cost high-temperature-resistant self-leveling mortar, which is composed of the following components by weight percentage: 5-8% of pure calcium aluminate cement, 1.2-2.5%of Bonite, 18-22% of fly ash, 22-30% of recycled corundum, 1-2% of fullerene, 0.02-0.05% of an early strength agent, 0.02-0.05% of a defoaming agent, 0.12-0.15% of a retarder, 0.15-0.25% of a water reducing agent and the balance silica powder. Main components of the high-temperature-resistant self-leveling mortar are fly ash, recycled corundum and silica powder, wherein the fly ash and the recycled corundum are industrial and building waste and are low in price; a small amount of pure calcium aluminate cement, Bonite and fullerene are added for cooperation so as to remarkably improve the hightemperature resistance of the mortar. The fire-resistant temperature of the low-cost high-temperature-resistant self-leveling mortar can reach 1500DEG C or above.
本发明公开了一种低成本的耐高温自流平砂浆，由以下重量百分比的成分组成：纯铝酸钙水泥5‑8%、博耐特1.2‑2.5%、粉煤灰18‑22%、回收刚玉22‑30%、富勒烯1‑2%、早强剂0.02‑0.05%、消泡剂0.02‑0.05%、缓凝剂0.12‑0.15%、减水剂0.15‑0.25%和硅微粉余量。该耐高温自流平砂浆的主要成分为粉煤灰、回收刚玉和硅微粉，其中粉煤灰和回收刚玉均为工业和建筑废弃物，价格低廉；而本发明中加入少量的纯铝酸钙水泥、博耐特与富勒烯相配合就可以显著提升砂浆的耐高温性能，本发明的低成本耐高温自流平砂浆的耐火温度可以达到1500℃以上。
