水刷石、面砖、马赛克墙面由于原材料质量、施工管理水平和外界条件变化等因素影响,经常产生墙面空鼓、污染、表面颜色明暗不均、缝隙不匀、墙面不平整等质量问题。近几年我们通过提高操作技术水平,改进施工工艺,加强科学管理,增强质量意识,基本上消除了上述质量通病。一、水刷石墙面水刷石墙面空鼓、裂缝有两种,一种由底子灰与墙面粘结不牢造成,面积较大;另一种由面层水刷石与底子灰粘结不牢造成,面积较小。水刷石墙面产生空鼓、裂缝,除与原材料品种、质量有关外,还与操作工艺有关。上述前一种状况主要是未提前浇水湿润,混凝土墙面未凿毛,或底子灰内掺入的石灰膏未熟化透等原因;后一种状况的主要原因
Water brush stone, tile, mosaic wall surface due to the impact of factors such as the quality of raw materials, construction management and external conditions, often produce empty walls, pollution, uneven surface color, uneven gaps, uneven walls and other quality issues . In recent years, we have basically eliminated the aforementioned quality problems by improving the level of operation technology, improving construction technology, strengthening scientific management, and enhancing quality awareness. 1. There are two kinds of empty drums and cracks in the water brush stone wall surface, and there are two kinds of cracks, one is caused by the loose bonding between the bottom ash and the wall surface, and the other is larger by the surface layer; Bonding is not strong and the area is small. Water brush stone wall hollowing, cracks, in addition to the variety and quality of raw materials, but also related to the operating process. The former situation mentioned above is mainly due to reasons such as no watering and moistening ahead of time, no concrete chiseling on the concrete wall, or lime paste incorporated in the base ash;
