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.
