1 按照掺量要求,仔细计量外加剂,将外加剂添加到砂浆中加水搅拌至均匀即可。本产品基本无减水效果,按照配合比设计稠度标准加水即可。
2.掺加ZK-MS湿拌砂浆外加剂的砂浆上墙干燥时间会有一定影响,当墙面湿度正常且空气湿度正常,施工厚度在2cm内时,上墙干燥时间与现场拌制砂浆一致;墙面湿度很高或空气湿度很高或施工厚度超过2cm,上墙干燥时间会稍长,比现场拌制要长1~3小时;墙面湿度特别高且空气湿度特别高且厚度超过2cm,上墙干燥时间会特别长,建议施工时可以提前对墙面进行湿淋或者对施工很厚的部位先提前进行甩浆,第二天进行补平。
3.砂浆用砂去除公称粒径>4.75的颗粒,建议含泥量控制在3%以内,绝对不能使用泥块含量超标的砂,容易使砂浆产生大面积的塑性製纹。细度模数2.4-2.6最佳。
4.注意砂浆用砂含泥量、粗细程度及含水率的变化,材料的变动可能引起砂浆稠度变化。
5.当砂浆用粉料(水泥、粉煤灰、矿渣粉)发生变化时,要通过实验验证。
6.建议砂浆出场稠度控制在85-95mm,密度控制在1950~2050Kg/m³。太粘的砂浆易粘刮尺,不粘的砂浆刮上墙很费力。
7.生产砂浆前,要先涮洗干净搅拌机和运输罐车,生产完砂浆后同样需要对搅拌机和运输罐车进行涮洗干净。
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.
