Technical Principle
The molecular chain of PCE is comb shape. The main chains of Polycarboxylate Based Superplasticizer molecular are absorbed onto the surface of the cement granules, which can effectively hinder the hydration, enhance its flowing retention ability, the branch chains surrounded by the cement granules, play dual roles of steric hindrance and electrostatic repulsion.
Advantages/Characteristics:
Polycarboxylate based superplasticizer can provide high-quality durable concrete.
1. Strong plasticizing effect improves the initial processability, easier placement and faster strength development.
2. Minimize the water-cement ratio to produce high-strength concrete. 3. The high-performance concrete can be delivered to the site at any time.
4. It can be used alone or combined with other admixtures to make pumped concrete, ready-mixed concrete and other special concrete.
Dosage:
1. Generally, the dosage range is 0.25%—0.8% per 100kg of total cementitious materials, it can be beyond this range properly for special cements or aggregates.
2. The compounding rate for specific cements is determined by tests. Recommended stirring time is at least 150s for good water reducing effect. The concrete mixing tests should be carried out before using so as to assure the concrete quality.
3. superplasticizer can be compounded with various retarders, defoamers, air entraining agents and sodium lignosulphonate.
Application:
It is applicable to various ready mix concrete , precast concrete, mortar.
