High water reducing polycarboxylic acid water reducing agent mother liquor
Polycarboxylic acid superplasticizer is a copolymerization product of carboxylic acid and brittle graft, which is developed by combining the latest technology of polycarboxylic acid superplasticizer at home and abroad. The product can be produced at room temperature, and the production process is simple and environmentally friendly. The product does not contain chloride ion, has the characteristics of high water reduction rate, low content, slump retention ability is good, strong adaptability, according to the requirements of the project preparation of different performance of concrete ten, can be applied to thousands of road, railway and other key projects, can also be applied to the production of commercial concrete mixing station.
Application field
Cement-based building materials. Applicable to intervention mixing, pumping, precast and various high strength, high performance concrete.
Characteristics and advantages
(1) high water reduction rate: according to the national standard GB 8076-2008 "concrete admixture" requirements for testing, adding polycarboxylic acid high-performance water reducing agent concrete water reduction rate can reach more than 30%;
(2) good early strength and enhancement effect; Under the same conditions, mixed with the product after coagulation ten, 3d compressive strength can be increased by more than 160%, 28d compressive strength can be increased by more than 50%, on the national standard requirements, early strength and enhancement effect is higher than other types of high efficiency water reducing agent;
(3) Improvement of working performance of coagulant 10: the coagulant 10 prepared with the water-reducing agent has good workability and is not easy to bleed;
(4) The product has low alkali content, no chloride ion, and aims to improve the durability of coagulation:
(5) Strong product adaptability: The product has been verified by a variety of different labels and cement performance of different manufacturers, and has good compatibility with slag, fly ash and other mineral admixtures:
(6) Good product stability, non-toxic, non-irritating, long-term storage without precipitation, no stratification.

Use recommendations :
When used alone or combined with other varieties of polycarboxylic acid water-reducing agent (mother liquor), the mixture amount of folding-solid should be 0.05%~0.25% of the cementing material, and then added into the mixer with water after proportional dilution. If necessary, appropriate amount of entraining, defoamer, retarding and other components can be added to adjust the relevant properties.
