墙面抹灰空鼓的原因
影响墙面抹灰面不够密实的成因 1、墙面抹灰没有按相关技术规程的基本要求实行分道施工。 2、新拌砂浆超过施工开放时间或受到污染,而影响到砂浆的性能。 3、砂料没有作出过筛级配。 4、抹灰之前没有对基层上的凹凸不平及孔洞部位作出修补处理。 5、钉挂在墙面上的钢网未张拉牢固。 6、砂浆的和易性、粘连性与施工开放时间难以满足施工要求。 五、影响建筑品质的深层次根源 墙面以CL专用砂浆抹灰总体上: 1)表观密实度与平整度已有明显的改观; 2)已基本消除砌体墙面上的空鼓与开裂难题; 3)砼体基层上的大面积空鼓以及网状裂缝已得到了有效的控制。 但是,墙面局部出现空鼓与开裂的问题依然严峻。 1, wall plastering did not carry out the sub channel construction according to the basic requirements of the relevant technical regulations. 2. The new mortar exceeds the construction opening time or is polluted, and affects the performance of the mortar. 3, sand material did not screen gradation. 4. Before plastering, no bump and holes in the base are repaired. 5, the steel net that is fasten on the wall surface is not tensioned. 6, mortar workability, adhesiveness and construction opening time are difficult to meet construction requirements. Five, the deep root wall which affects the quality of the building, with the CL special mortar plastering on the whole: 1) the apparent density and the smoothness have been obviously improved; 2) has basically eliminated the bulge and cracking problem on the masonry wall; 3) the large area empty drum and the net crack on the concrete base have been effectively controlled. However, the problem of hollowing and cracking on the wall is still grim.
