Autoclaved aerated concrete raw material foaming process and aerated board
The invention relates to the field of autoclaved aerated concrete, and particularly discloses an autoclaved aerated concrete raw material foaming process and an aerated plate. The autoclaved aerated concrete raw material foaming process comprises the following steps: adding cement, lime, gypsum and fly ash into stirring equipment, and uniformly mixing; adding the air entraining agent into the stirring equipment, and continuously stirring; pouring the uniformly stirred mixture into a mold to obtain a blank body, carrying out ultrasonic vibration to eliminate bubbles, standing for gas generation after defoaming is completed, and maintaining the blank body molded by pouring for 2-4 hours at 40-60 DEG C and 85-95% humidity; feeding the cured green body into a still kettle for high-pressure steam curing, keeping the temperature of 180-200 DEG C and the pressure of 1.2-1.5 MPa in the still kettle, and curing for 8-12 hours to obtain the autoclaved aerated concrete. The autoclaved aerated concrete raw material foaming process solves the problems that existing autoclaved aerated concrete is slow in water absorption and moisture conduction, and the moisture content is not easy to control.
本申请涉及蒸压加气混凝土领域，具体公开了一种蒸压加气混凝土原料发泡工艺及加气板材。蒸压加气混凝土原料发泡工艺包括以下步骤：将水泥、石灰、石膏、粉煤灰加入搅拌设备中混合均匀；向搅拌设备中加入，将加气剂加入搅拌设备中，继续搅拌；将搅拌均匀的混合料浇注到模具中，得到胚体，并进行超声振动以消除气泡，消泡完成后静置发气，将浇注成型的坯体在40‑60℃、85‑95%湿度下，养护2‑4h；将养护后的坯体送入蒸压釜中进行高压蒸汽养护，蒸压釜内保持180‑200℃的温度和1.2‑1.5MPa的压力，养护时间为8‑12h，得到蒸压加气混凝土。本申请的蒸压加气混凝土原料发泡工艺解决现有蒸压加气混凝土存在吸水导湿缓慢，含水率不易控制的问题。
