Prefabricated component special polycarboxylic acid water reducer

Polycarboxylate Superplasticizer:

The special polycarboxylic acid superplasticizer for precast component is developed to meet the performance requirements of precast component concrete. By studying the structure, property and function of polycarboxylic acid water reducing agent, the molecular structure is designed reasonably, so that the product has the characteristics of high water reduction rate, viscosity reduction, low air entraining and early strength, so as to meet the requirements of precast component concrete.

Polycarboxylate superplasticizer is a new generation of high performance superplasticizer. It is developed on the basis of ordinary water reducing agents represented by wood calcium and high efficiency water reducing agents represented by naphthalene series. PCE is a highly efficient water reducing agent with the best application prospect and comprehensive performance. Therefore, it can be widely used in highways, Bridges, DAMS, tunnels, high-rise buildings and other projects.

Polycarboxylic acid superplasticizers have become one of the most important superplasticizers in the concrete admixture market because of their high water reduction rate, good effect, good adaptability to cement and slump resistance. With the construction of large-scale infrastructure such as nuclear power, water conservancy, Bridges and tunnels, especially the planning and implementation of railway passenger dedicated line network projects, the market demand for PCE polycarboxylate superplasticizers will show a trend of continuous growth.

Product characteristics

(1) high water reduction rate: according to the national standard GB8076-2008 "concrete admixture" test, water reduction rate can reach 50%;

(2) Viscosity reduction: by selecting the appropriate adsorption groups, adjusting the density and distribution of adsorption groups, so that the water reducing agent molecules adsorption quickly, efficient dispersion, so as to reduce the plastic viscosity of cement slurry and concrete yield stress, solve the problem of high grade precast concrete viscosity, weight, hardening, greatly improve its performance;

(3) Low entrained air: The relationship between the structure of polycarboxylic acid superplasticizer and entrained air was studied with the help of professional knowledge of surface chemistry. The molecular side chain of water reducing agent was modified and optimized, and the hydrophilic and oil-philic balance value of water reducing agent was adjusted to optimize the bubble size and stability in concrete, so as to make the internal structure of concrete more dense and meet the structural requirements of precast concrete.

(4) Early strength: by adjusting the length of the side chain of water reducing agent and choosing large molecular weight polyether, compared with ordinary water reducing agent, the hydration rate of cement can be improved to improve the early strength of precast concrete, and the late strength does not shrink;

(5) Good cement adaptability: the product through a variety of different labels, different manufacturers of cement performance verification, matching Huaxin, Yangfang, conch, Onoda, Three Gorges cement adapt well.

Scope of application

Suitable for pipe pile, pipe segment, track plate, prefabricated construction and other manufacturers to produce pipe pile, track plate, beam, plate, column and other precast components of high grade concrete, can realize the autoclave-free production of precast components, can also be applied to other high performance concrete.
