Functional admixture series

國家對建筑施工環保要求越來越高,混凝土商業化后,砂漿商業化也將是必然。本公司技術團隊通過大量的開發及驗證實驗,開發了ZK-MS濕拌抹灰砂漿外加劑。ZK-MS濕拌抹灰砂漿外加劑主要用于濕拌抹灰砂漿中調整砂漿開放時間、保水性、稠度、抗裂性等性能的外加劑。

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.


主要技術性能
The main technical performance

1.砂漿開放時間(開放時間是指砂漿的可用時間,即從砂漿生產到砂漿失去和易性這段時間。)可調:根據施工工地開放時間要求及季節變化帯來的溫濕度變化,可以進行調整。

2.砂漿粘度可調:砂漿內砂的粗細會對砂漿的粘度帶來影響,砂粗粘度降低,反之,砂細粘度增加。一般控制砂的細度模數在2.4-2.6內最佳。另外,溫度高時砂漿的粘度也會降低。根據不同材料及使用條件可對砂砂漿外加劑方案進行調整,以滿足施工要求。

3.良好的保水性能:有效控制砂漿內水分的散失, 摻加ZK-MS濕拌砂漿外加劑,可以使砂漿具有更佳的保水性能,避免砂漿在開放時間內靜置泌水。

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.


注意事項
Notes

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.

施工現場濕拌砂漿的存放

Storage on site

建議根據施工現場情況設置濕拌砂漿專用儲存池(罐),儲存池(罐)不得漏水或嚴重吸水,并加蓋遮陽、防水頂棚,最好能做到砂漿表面可以用塑料薄膜覆蓋,以防止砂漿水分散失。

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.


濕拌砂漿使用環境

Wet mortar usage conditions

不應在日常溫度低于5℃的環境下生產使用,應采取蓄熱保溫措施改善生產施工環境,應避免在炎熱高溫和大風季節時段施工,應做好保濕養護工作。

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.
