摘要
为了能够使得沙漠砂蒸压加气混凝土砌块更好的应用于村镇建筑。本试验分别对B06级、B07级以及涂有一层硅酸乙酯(TEOS)的B06级沙漠砂蒸压加气混凝土砌块进行了冻融试验的研究,通过质量损失和强度损失分析试块的耐久性能,并利用电镜扫描技术对以上三类试块的微观结构进行分析。涂有TEOS的B06级试块的质量损失明显要比未涂的小得多,但强度损失的优势并不明显;对于B07级沙漠砂蒸压加气混凝土试块,其质量损失基本在5%以内,强度损失基本一致且在0.6%左右,可见将B07级的试块应用于村镇建筑墙体材料是可行的,但B06级试块应考虑在试块表面采用多层TEOS、浸泡或其他形式改善试块的耐久性能。
In order to make desert sand autoclaved aerated concrete block better applied to village buildings,this test is for B06 grade,B07 grade and B06 grade desert sand autoclaved aerated concrete coated with a layer of ethyl silicate(TEOS).The block was studied by freeze-thaw test.The durability of the test piece was analyzed by mass loss and strength loss,and the microstructure of the above three test pieces was analyzed by electron microscopy.The results show that the quality loss of the B06 grade test block coated with TEOS is obviously smaller than that of the uncoated one,but the advantage of strength loss is not obvious.For the B07 grade desert sand autoclaved aerated concrete test block,the quality loss is basically Within 5%,the strength loss is basically the same and around 0.6%.It can be seen that it is feasible to apply the B07 grade test block to the wall material of the village building,but the B06 test block should consider using multiple layers of TEOS and soaking on the surface of the test block.Or other forms to improve the durability of the test block.
