Preparation process of high-strength foam concrete
The invention discloses a preparation process of high-strength foam concrete, which comprises the following steps: adding 1.6-2.8 parts by mass of water and sodium hydroxide into a stirrer, and completely dissolving the sodium hydroxide; adding 0.03 to 0.1 part by mass of hydroxypropyl methyl cellulose, 0.05 to 0.2 part by mass of polyvinyl alcohol and 1 part by mass of palm fiber into the sodium hydroxide solution; adding 180 to 594 parts by mass of cement and 120 to 600 parts by mass of coal ash and 150 to 510 parts by mass of water into the mixture, and stirring; adding 0.5 part by mass of a high-efficiency water reducing agent into the mixture, then adding 0.4-0.7 part by mass of aluminum powder paste, and stirring for 90 seconds to obtain foam concrete; foam concrete is placed in the mold frame to be naturally foamed for 30 minutes; and after the strength of the foam concrete meets the requirement, demolding, and cutting the foam concrete into blocks.
本发明公开一种高强度泡沫混凝土的制备工艺,包括:将水和氢氧化钠加入搅拌机内,将氢氧化钠完全溶解,添加的氢氧化钠是1.6至2.8质量份;向氢氧化钠溶液内添加0.03至0.1质量份的羟丙基甲基纤维素、0.05至0.2质量份的聚乙烯醇和1质量份的棕丝;向混合物内加入水泥和煤灰进行搅拌,添加的水泥重量180至594质量份、煤灰重量120至600质量份,添加的水重量是150至510质量份;向混合物内加入0.5质量份的高效减水剂,之后再添加0.4至0.7质量份的铝粉膏搅拌九十秒,得到泡沫混凝土;将泡沫混凝土放至模框内自然发泡30分钟;泡沫混凝土的强度达到要求之后,脱模,将泡沫混凝土切割成块。
