    水泥砂浆地面易出现的问题及处理办法
    来源:http://www.jndmzp.com   时间:2013-11-28 11:19:46

    水泥砂浆常被采用于楼地面面层,很容易出现裂缝、起砂、强度不够等质量通病。这些通病会直接危害到房屋的质量,影响使用功能。
    Cement mortar is often used in floor surface layer, it is easy to crack, sand, insufficient strength of quality defects. These problems will directly endanger the quality of housing, affect the use of function.
    水泥砂浆济南地面找平弊病及原因
    Shortcomings and reasons of Ji'nan ground leveling cement mortar
    1、 开裂。由于气候温度的变化(热胀冷缩),使地面被破坏出现裂缝;又或是由于基层的水性很强,凝固过程中的水泥砂浆地面与一部分水发生化学反应,其余的水被蒸发掉,体积变小造成地面裂缝。
    1, cracking. Because of the change of climate temperature (thermal), so that the ground is broken crack; or the water level is very strong, in the process of solidification of cement mortar ground and a portion of the water and chemical reaction, the rest of the water is evaporated, smaller size causing the ground to crack.
    2、 地面起砂。过早的在济南地面找平基层上涂刷水泥浆结合层,当铺面层时,所刷的水泥浆已经风干硬化,不但没有粘结力,反而起了隔离层作用,终导致地面起砂。
    2, the floor sand. The coating of cement slurry in early Ji'nan ground leveling base bonding layer, the surface layer of cement slurry, the brush has hardened, not adhesive force, but the isolation layer, eventually led to the floor sand.
    3、 强度不够。水灰比过大造成黏度过高,降低了地面表面的强度、硬度,影响地面的耐磨性能。
    3, the lack of strength. Large water cement ratio caused by high viscosity, lower strength, ground surface hardness, impact wear resistance of the ground.
    处理办法
    Treatment methods
    a. 一定要给基层充分浇水湿润。在施工的前一天,建议对基层浇水让其湿润,使得基层表面清洁干净,但是注意不能积水,确保面层与基层黏结牢固,并施工切割缝以预防地面开裂。。
    A. must give the full watering humid. On the day before the construction, suggestions on the basic water to wet the surface clean, clean, but not water, to ensure that the bonding surface and base construction firm, and cutting seam to prevent cracking of the ground..
    b. 要注意控制涂抹水泥浆结合层的时间,增加面层与基层之间的粘结力。基层干温程度控制在0.4~0.5.注意不要先撒干水泥后浇水的扫浆方法。
    B. should pay attention to control of smear slurry with layers of time, increase the adhesive force between surface layer and base layer. The temperature and the degree of control in 0.4~0.5. do not put dry method cement slurry water after the dry.
    c. 水泥砂浆的水灰比应该低于0.4,其标准的粘稠度也不应该大于3.5cm。
    C. cement mortar water cement ratio should be less than 0.4, the standard viscosity should not be greater than 3.5cm.
