Foamed concrete admixture and preparation method thereof
The invention discloses a foamed concrete admixture and a preparation method thereof.The foamed concrete admixture comprises fly ash, an accelerator, a foam stabilizer, a water reducing agent, an inorganic compound, an anti-freezing agent, an early strength agent and fly ash, and the mass ratio of the fly ash to the accelerator to the foam stabilizer to the water reducing agent to the inorganic compound to the anti-freezing agent to the early strength agent is reasonably selected; the setting and hardening rate of the slurry and the foaming rate of the foaming agent reach a dynamic balance, the setting time is adjusted by doping the accelerator, the stability of the foamed concrete structure is improved, the forming process and strength development of the hardened body structure are accelerated, the setting rate of the concrete and the foaming rate of the foaming agent are coordinated, and the foaming effect is improved. The foaming quality, the anti-freezing property and the compression resistance of the foamed concrete are also ensured, so that the quality of the foamed concrete is improved.
本发明公开了一种发泡混凝土外加剂及其制备方法，包括粉煤灰、速凝剂、稳泡剂、减水剂、无机化合物、防冻剂、早强剂和粉煤灰，通过合理选择粉煤灰、速凝剂、稳泡剂、减水剂、无机化合物、防冻剂和早强剂的质量配比使得在使用外加剂的过程中，使得料浆的凝结硬化速率与发泡剂发泡速率达到一种动态平衡，通过掺加速凝剂对凝结时间进行调节，提高了发泡混凝土结构的稳定性、加速硬化体结构形成过程和强度发展，使得混凝土的凝结速率和发泡剂发泡速率相协调，还保证了发泡混凝土的发泡质量以及防冻性和抗压程度，进而提高发泡混凝土质量。
