Non-autoclaved titanium slag-based aerated concrete and preparation method thereof
The invention discloses non-autoclaved titanium slag-based aerated concrete and a preparation method thereof. The non-autoclaved titanium slag-based aerated concrete is prepared from the following components in parts by mass: 60 to 80 parts of cement, 100 to 200 parts of dechlorinated titanium extraction tailings, 200 to 300 parts of fly ash, 15 to 25 parts of quick lime, 10 to 20 parts of desulfurized gypsum, 200 to 300 parts of water and 0.8 to 1.1 parts of aluminum powder paste. According to the invention, the proportion of the dechlorinated titanium extraction tailings, the fly ash and the desulfurized gypsum is adjusted, and the autoclaved curing-free conditions are further optimized to prepare the high-quality aerated concrete, so that the utilization rate of a large amount of industrial wastes is increased. In the process of preparing the aerated concrete, the curing conditions are adjusted to be that the temperature is 20 +/-2 DEG C and the humidity is larger than or equal to 95% until foaming is completed, then standard curing and natural curing are conducted, energy consumption of high-temperature steam and high pressure during autoclaved curing is reduced, and the titanium slag-based aerated concrete prepared under the same condition has a smaller dry shrinkage value.
本发明公开了一种免蒸压钛渣基加气混凝土及其制备方法，所述免蒸压钛渣基加气混凝土以质量份计包括，水泥60‑80份、脱氯的提钛尾渣100‑200份、粉煤灰200‑300份、生石灰15‑25份、脱硫石膏10‑20份、水200‑300份和铝粉膏0.8‑1.1份。本发明调整脱氯后的提钛尾渣、粉煤灰和脱硫石膏的配比，并进一步优化免蒸压养护的条件制备高质量的加气混凝土，提高了大宗工业废弃物的利用率。本发明在制备加气混凝土过程调整养护条件为在温度20±2℃、湿度≥95％至发泡完成，随后进行标准养护和自然养护，节约了在蒸压养护时高温蒸汽和高压的能源消耗，并且同等条件下制备的钛渣基加气混凝土具有更小的干缩收缩值。
