墙面抹灰的一些基本要求是什么?

来源:https://www.jnfhjc.com 日期:2020-05-07 发布人:admin

  一点是标准前应先铺上一大片灰泥。抹灰应分层进行,厚度为5mm至7mm。抹灰砂浆和水泥砂浆,每道厚度为7mm ~ 9mm。抹灰层总厚度大于35mm时,应采取相应的加固措施。

  One is that a large area of plaster should be laid before the standard. Plastering shall be carried out in layers of 5mm to 7mm. Plastering mortar and cement mortar, each thickness of 7mm ~ 9mm. When the total thickness of plastering layer is more than 35mm, corresponding reinforcement measures shall be taken.
  第二点是如果使用水泥砂浆和水泥砂浆抹灰器,应等到前一层抹灰器设置好后,才可以允许抹下一层抹灰。如果用石灰砂浆抹灰,则应等到前一层七至八层干燥后,再抹后一层。
  The second point is that if cement mortar and cement mortar plasterer are used, the next layer of plastering shall not be allowed until the previous layer of plasterer is set. If plastering with lime mortar, wait until the first seven to eight layers are dry before plastering the second layer.

  第三点是抹灰强度的底面不能低于抹灰强度的面。
  The third point is that the bottom surface of plastering strength cannot be lower than the surface of plastering strength.
  第四点是调好水泥砂浆混合后,应在初凝前用完,通常有硬砂挡,即砂浆开始凝结后不能继续使用。
  The fourth point is that after the cement mortar is mixed, it should be used up before the initial setting, and there is usually a hard sand block, that is, the mortar can not be used after it starts to set.
  目前,灰浆出厂检验包括初凝时间、抗压强度、密度、稠度、收缩率。抹灰干混砂浆有三个相关标准和规范:自凝加气混凝土砌体砂浆和抹灰砂浆(jc890-2001)、建筑砂浆基本性能试验方法(jgj70-1990)、水泥砂浆干缩试验方法(JC/ t603-1995)。性能测试包括四个方面:材料的标准稠度、砂浆的保水性能、砂浆的分层程度和流动性。
  At present, the factory inspection of mortar includes initial setting time, compressive strength, density, consistency and shrinkage. There are three relevant standards and specifications for plastering dry concrete mortar: self setting aerated concrete masonry mortar and plastering mortar (jc890-2001), basic performance test method for building mortar (jgj70-1990), and dry shrinkage test method for cement mortar (JC / t603-1995). The performance test includes four aspects: the standard consistency of the material, the water retention performance of the mortar, the stratification degree and the fluidity of the mortar.
