Chemical PCE Based Superplasticizer , Concrete Additive Superplasticizer In Cement
PCE can be widely used in ordinary concrete and high performance concrete
Polycarboxylic acid superplasticizer is the third generation of new superplasticizer for concrete. Compared with naphthalene superplasticizer, polycarboxylic acid superplasticizer has the advantages of high water reduction rate, high strength, low shrinkage, low secretion and low slump loss. Polycarboxylate superplasticizer has relatively good adaptability with different cement. Compared with naphthalene superplasticizer, the strength of polycarboxylate superplasticizer concrete increases faster in early and late periods, especially the strength of high-strength concrete increases more obviously in late periods.
Special Features
PCE offers the following benefits for the precast concrete industry:
-Extremely high-water reduction
-High early strength development
-Shorter demoulding time
-Energy-saving (reduced steam curing)
-Produce Rheoplastic and Rheodynamic concrete having a low water to cement ratio
-Optimize the curing cycles by reducing curing times or temperatures
-Eliminate heat curing
-Eliminate the energy required for placing, compaction and curing
-Increase productivity
-Improve surface appearance
-Produce durable precast concrete elements as per EN 206-1
As compared with the traditional superplasticizers, the engineering properties such as early and ultimate compressive and flexural strengths, bond to steel, modulus of elasticity, shrinkage, creep, and impermeability are greatly improved.
Usage
1) PCE can be widely used in ordinary concrete and high-performance concrete, especially having excellent performance in high-performance concrete of early strength.
2) PCE can be applied to industrial and civil construction, pumping concrete construction in hydraulic projects, ports, traffic, municipal and railways. It can also be used for making special concrete, such as high strength, ultra-high strength, high impermeability, early strength, self-leveling and steel fiber types.
