GPC-500 is a new generation of environmentally friendly polycarboxylate high-performance water reducing agent developed by our company, this series of water reducing agent can greatly improve the plasticity index of freshly mixed concrete due to its extremely high water reduction rate, thereby improving the pumping and constructability of concrete, and also showing excellent performance in strength growth. The product can be widely used in ordinary concrete, pumped concrete, superfluidic self-compacting and high-strength and high-durability concrete, especially in high-strength and high-performance concrete, precast concrete, superfluidic vibration-free self-leveling concrete applications have excellent performance.
Excellent dispersion performance: Excellent dispersion performance can provide extremely high water reduction effect, water reduction rate is as high as 35%, which provides a guarantee for improving coagulation and low economic costs.
Wide adaptability: very wide adaptability, all kinds of Portland cement, ordinary Portland cement, slag Portland cement and various admixtures have good dispersion and plasticity.
Excellent durability: Low shrinkage, low alkali content and chloride ion content can improve the durability of concrete.
Higher growth rate: There is a higher early strength growth rate, improved shrinkage performance and reduced carbonization rate of concrete.
Molecular controllability: The water reduction rate, plasticity retention and air entrainment performance of this series of water reducing agents can be adjusted by adjusting the molecular weight of the molecular main chain, the length of the side chain, the density and the type of side chain gene clusters.
Good adhesion: It can improve the cohesion of concrete, so that the concrete has good workability, no delamination, no segregation, no water secretion.
Green environmental protection: no formaldehyde and other harmful ingredients.
How to use
The recommended dosage range is 0.25% ~ 0.8%. For the specific cement and mix ratio, the optimal dosage should also be determined by testing.
When using, it can be mixed with mixing water before adding, or added to the concrete mixer at the same time. In order to achieve the best water reduction effect, the stirring time is recommended to be not less than 120s.
The product can be combined with various functional admixtures such as retarder, defoamer, and air entrainment, and the best composite performance should be determined by test before use.
Since this product is a water reducing agent stock solution with a solid content of 40%, it is not a terminal product used in concrete production, it is recommended that customers reduce the solid content of the product before use, and determine the best content and performance through testing, and if necessary, can be combined with other admixture products.
Technical Note
The main chain of this variety of polycarboxylic acid high-performance water reducing agent molecules is firmly adsorbed on the surface of cement particles, playing the dual role of steric hindrance and electrostatic repulsion, and the side chain is surrounded by cement particles, which is completely different from the mechanism of dispersing cement particles by electrostatic repellence of traditional water reducing agents, so it has better dispersion capacity and water reduction effect, and finally makes the comprehensive performance of concrete products get a qualitative leap.
Moreover, the side chain freedom of this variety polycarboxylic acid water reducing agent is higher than that of conventional polycarboxylic acid water reducing agent, which has super high adaptability and significant viscosity reduction effect.
