国家对建筑施工环保要求越来越高,混凝土商业化后,砂浆商业化也将是必然。本公司技术团队通过大量的开发及验证实验,开发了ZK-MS湿拌抹灰砂浆外加剂。ZK-MS湿拌抹灰砂浆外加剂主要用于湿拌抹灰砂浆中调整砂浆开放时间、保水性、稠度、抗裂性等性能的外加剂。

With the higher environmental requirements of building operations and commercialization of concrete,it's inevitable for mortar to become commercialized.Based on vast development and confirmatory experiments,our technical team develops ZK-MS wet plastering mortar admixture,which is used to adjust mortar opening time、water-retaining property、denseness and crack resistance during stirring wet plastering mortar.


主要技术性能
The main technical performance

1.砂浆开放时间(开放时间是指砂浆的可用时间,即从砂浆生产到砂浆失去和易性这段时间。)可调:根据施工工地开放时间要求及季节变化帯来的温湿度变化,可以进行调整。

2.砂浆粘度可调:砂浆内砂的粗细会对砂浆的粘度带来影响,砂粗粘度降低,反之,砂细粘度增加。一般控制砂的细度模数在2.4-2.6内最佳。另外,温度高时砂浆的粘度也会降低。根据不同材料及使用条件可对砂砂浆外加剂方案进行调整,以满足施工要求。

3.良好的保水性能:有效控制砂浆内水分的散失, 掺加ZK-MS湿拌砂浆外加剂,可以使砂浆具有更佳的保水性能,避免砂浆在开放时间内静置泌水。

1.Mortar opening time (which means the avalilable time of mortar,namely the time from mortar's production to workability loss)adjustment:based on the opening time which construction site requires and temperature and humidity changes owing to seasonal variation,the opening time can be adjusted.

2.Mortar viscosity adjustment:different degrees of thickness of sand inside the mortar exert an effect on the viscosity of mortar.The thicker the sand is,the lower the viscosity is and vice versa.The fineness modulus of sand should range from 2.4 to 2.6. In addition,when the temperature is high,the viscosity of mortar decreases.Based on the different materials and conditions,we will provide different mortar admixture schemes to satisfy the requirements of construction.

3.Good water retention capacity:if ZK-MS wet plastering mortar admixture is added,the moisture in the mortar will be well kept and sustain a good water retention capacity and avoid bleeding when standing in the open time.


注意事项
Notes

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.


包装、储存和运输

施工现场湿拌砂浆的存放

Storage on site

建议根据施工现场情况设置湿拌砂浆专用储存池(罐),储存池(罐)不得漏水或严重吸水,并加盖遮阳、防水顶棚,最好能做到砂浆表面可以用塑料薄膜覆盖,以防止砂浆水分散失。

Special storage pool (jar) for wet plastering mortar should be placed based on the construction site conditions.The pool (jar) is not allowed to leak or absorb water seriously and put sunshade and waterproof ceiling.Besides,the surface of mortar should be covered by plastic membrane to sustain water.


湿拌砂浆使用环境

Wet mortar usage conditions

不应在日常温度低于5℃的环境下生产使用,应采取蓄热保温措施改善生产施工环境,应避免在炎热高温和大风季节时段施工,应做好保湿养护工作。

The mortar admixture shall not be used below 5℃ and should improve construction conditions by means of heat accumulation and warmth retention.Meanwhile,the mortar admixture avoids scorching temperatures and strong wind season and keeps wet.
