1 按照摻量要求,仔細計量外加劑,將外加劑添加到砂漿中加水攪拌至均勻即可。本產品基本無減水效果,按照配合比設計稠度標準加水即可。
2.摻加ZK-MS濕拌砂漿外加劑的砂漿上墻干燥時間會有一定影響,當墻面濕度正常且空氣濕度正常,施工厚度在2cm內時,上墻干燥時間與現場拌制砂漿一致;墻面濕度很高或空氣濕度很高或施工厚度超過2cm,上墻干燥時間會稍長,比現場拌制要長1~3小時;墻面濕度特別高且空氣濕度特別高且厚度超過2cm,上墻干燥時間會特別長,建議施工時可以提前對墻面進行濕淋或者對施工很厚的部位先提前進行甩漿,第二天進行補平。
3.砂漿用砂去除公稱粒徑>4.75的顆粒,建議含泥量控制在3%以內,絕對不能使用泥塊含量超標的砂,容易使砂漿產生大面積的塑性製紋。細度模數2.4-2.6最佳。
4.注意砂漿用砂含泥量、粗細程度及含水率的變化,材料的變動可能引起砂漿稠度變化。
5.當砂漿用粉料(水泥、粉煤灰、礦渣粉)發生變化時,要通過實驗驗證。
6.建議砂漿出場稠度控制在85-95mm,密度控制在1950~2050Kg/m3。太粘的砂漿易粘刮尺,不粘的砂漿刮上墻很費力。
7.生產砂漿前,要先涮洗干凈攪拌機和運輸罐車,生產完砂漿后同樣需要對攪拌機和運輸罐車進行涮洗干凈。
1. According to the requirements of amount of admixture,add admixture to the mortar,mix with water and stir evenly.The product has no slushing,so mix with water based on the mix proportion.
2. The mortar which is added the ZK-MS wet plastering mortar admixture might affect the drying time in some extent.When the humidity of wall and atmosphere is normal,the construction thickness is within 2cm and the drying time is in accordance with the mixed mortar on site;if the humidity of wall and atmosphere is high or the construction thickness is above 2cm,the drying time is1~3 hours longer than the former;if the humidity of wall and atmosphere is extremely high or the construction thickness is above 2cm,the drying time will belong and we recommend the wall should be splashed wet or add slurry on the thick part in advance and fill in the next day.
3.The sand whose nominal maximum aggyegate size is more than 4.75 should be wiped off and the quantity of silt content should be controlled within 3%.The sand whose silt content are out of limit are forbidden because such sand leads to a large area of ductility crack in mortar.The fineness modulus should range from 2.4 to2.6.
4. Pay attontion to the changes of silt content,degree of thickness and moisture content.The changes of materials may have an influence on the consistence of mortar.
5.When the powder(cement,coal ash and slag powder) in the mortar changes,it should be tested by experimental verification.
6.The consistence of mortar should be between 85cm-95cm and its density should be between 1950~2050Kg/m3.If the mortar is too viscous and it is easy to adhere to the darby.Instead,if not viscous,it is difficult to scrape on the wall.
7.Before the production of mortar,the agitators and tank trucks must keep clean;after production,the agitators and tank trucks should be cleaned.
