怎样防止砂浆粘结性不好的现象?

来源:https://www.jnfhjc.com 日期:2021-04-12 发布人:juyehe

砂浆的装备比例、选料、勾缝剂的挑选等都会影响后期的运用作用,劣质的砂浆会导致粘结作用不佳,严重的会导致外墙瓷砖不久就会脱落。所以购买砂浆一定要挑选高质量的,并且还要充沛做好防治砂浆粘结性欠好现象的准备。

The proportion of mortar equipment, the selection of materials and the selection of pointing agent will affect the later application. Poor quality mortar will lead to poor bonding effect, and serious will cause the external wall tiles to fall off soon. Therefore, the purchase of mortar must select high-quality, and also fully prepared to prevent the phenomenon of mortar adhesion is not good.
1、禁止用于砖垒墙。砌筑前1~2d应将砖浇湿,使砌筑时烧结一般砖和多孔砖的含水率到达10%~15%;灰砂砖和粉煤灰砖的含水率到达8%~12%。
1. It is forbidden to use on brick walls. The brick should be wet 1-2 days before masonry, so that the moisture content of fired general brick and perforated brick can reach 10% - 15%; the moisture content of lime sand brick and fly ash brick can reach 8% - 12%.
2、冬期施工时,在正温度条件下也应将砖面恰当湿润后再砌筑。负温下施工无法浇砖时,应恰当增大砂浆的稠度。对于9度抗震设防区域,在严冬无法烧砖情况下,不能进行砌筑。
2. In winter construction, under the condition of positive temperature, the brick surface should be properly wetted before masonry. When the brick cannot be poured under negative temperature, the consistency of mortar should be properly increased. For the seismic fortification area of degree 9, masonry can not be carried out in the case that bricks cannot be fired in severe winter.
3、当采用铺浆法砌筑时,必须操控铺浆的长度,一般气温情况下不得超越750mm,当施工期间气温超越30℃时,不得超越500mm。
3. When the mortar laying method is adopted, the length of mortar laying must be controlled. Generally, the temperature shall not exceed 750mm. When the temperature exceeds 30 ℃, it shall not exceed 500mm.

4、改善砌筑办法。不宜采取铺浆法或摆砖砌筑,应推行“三一砌砖法”,即运用大铲,一块砖、一铲灰、一挤揉的砌筑办法。
4. Improve masonry methods. It is not suitable to adopt the slurry laying method or brick laying method, but should implement the "three one brick laying method", that is, using a large shovel, one brick, one shovel of ash, and one kneading method.
5、改善砂浆和易性是确保灰缝砂浆丰满度和进步粘结强度的关键。砂浆原材料的挑选很重要。沙子水泥要在保质期内,增稠剂纤维素醚和进步砂浆粘接性的可再涣散乳胶粉要从正规企业挑选。
5. Improving mortar workability is the key to ensure mortar fullness and improve bonding strength. The selection of raw materials for mortar is very important. Sand cement should be within the shelf life, thickener cellulose ether and re laxable latex powder should be selected from regular enterprises.
挑选什么样的砂浆将决定了后期的运用作用,现在生产砂浆的厂家也越来越多了,挑选一家正规的厂家,将会防止许多不必要的麻烦。
