由吉林建筑工程学院非金属建材研究室傅广生等研制的“改性菱苦土轻质墙体制品”于1993年7月在长春通过省级鉴定.该制品以菱苦土、粉煤灰、氯化镁、泡沫剂和部分填加剂为原料,经搅拌注模,干热(20℃～30℃)条件下养护24h而成.其技术指标:干体密度为500～650kg/m~3,抗压强度为2.49～4.95MPa,抗折强度为1.9～2.4MPa,导热系数为0.065～0.15 W/m·k.干缩值0.013,24h吸水率为22.66～25.36%.该制品生产工艺较为简单,能耗少,无污染,可以大量利用工业废渣.其成本与加气混凝土相当.
The “Modified Ramsar Lightweight Wall Products” developed by the Non-Metallic Building Materials Research Institute of Jilin Institute of Architecture and Engineering was passed by the provincial level in Changchun in July 1993. The product is made from magnesite, fly ash, and magnesium chloride. , foaming agent and some additives as raw materials, after mixing injection molding, dry heat (20 °C ~ 30 °C) conditions curing 24h. Its technical indicators: dry body density of 500 ~ 650kg/m ~ 3, compression The strength is 2.49~4.95MPa, the flexural strength is 1.9~2.4MPa, the thermal conductivity is 0.065~0.15 W/m*k, the dry shrinkage value is 0.013, and the water absorption rate is 24.66~25.36% at 24h. The production process of this product is relatively simple and can Low consumption, no pollution, can make heavy use of industrial waste. Its cost is equivalent to that of aerated concrete.
