This product is a powder polycarboxylic acid water reducing agent with high water reduction and high slump retention type independently developed by our company. In addition to the characteristics of inherent powder water reducer, its biggest advantage is that it has very excellent slump retention. It can be directly dissolved with water to prepare liquid water reducing agent, and each performance index can achieve the performance of liquid polycarboxylic acid pumping agent, which makes it very convenient in the application process. It can be used in remote areas and only needs to be simply stirred and dissolved to achieve the needs of rapid plant construction. The product has the characteristics of uniform particles, low water content, good solubility, high water reduction and high slump preservation.
Product Features
High water reduction rate: it can make the water reduction rate reach more than 25%, and greatly improve the fluidity under the condition of the same amount of water added to concrete;
High slump retention: The traditional polycarboxylic acid powder water reducing agent will cause certain damage due to high temperature in the spray drying process. This greatly reduces the slump retention performance of liquids after conversion into solids. SP-409 is manufactured using a special process so that the carboxylic acid group is not destroyed during the powder manufacturing process, thereby retaining the slump retention of the original liquid mother liquor.
Good solubility and fast dissolution rate: Due to its uniform particles, the specific surface area is large. Therefore, it can be dissolved very quickly during the water dissolution process. And there are no obvious impurities after dissolution.
Recommended dosage
The recommended dosage in various dry powder materials is 0.2~0.3% of cementitious materials. After dissolution, replace the liquid polycarboxylic acid water reducing agent, and convert it according to the actual solid content after dissolving.
Scope of application
This product is suitable for the range of liquid polycarboxylic acid water reducing agent after being configured as a liquid, and is suitable for ready-mixed and cast-in-place concrete in various industrial and civil buildings. It is also suitable for special concrete such as high strength and high performance, high durability, superfluidic vibration-free self-leveling, self-compacting and steel fiber; Precast concrete, concrete transported over long distances, commercial concrete, etc.
It is especially suitable for construction sites in remote areas that are not suitable for factory construction, and only simple mixing equipment can meet the construction requirements.
