Early Strength Polycarboxylate Superplasticizer (PCE)

A functionality concrete admixture to increase the early strength for prefabricated concrete

Early Strength Polycarboxylate Superplasticizer (PCE)

Description:

The early strength polycarboxylate superplasticizer agent improves the cement hydration rate and promotes the early strength development of cement without sacrificing concrete pumping performance. It was redesigned by introducing the larger special polyether side chain and adjusting molecular weight and structure of the polymer. The special polyether was redesigned by introducing the EO/PO block to adjust the HLB value to control the air-entraining property of the polycarboxylate superplasticizer. Furthermore, the size and stability of the bubble are optimized to improve air consistency. It can be widely used in precast concrete, pipe pile concrete, segment concrete, etc.

Applications:

  • High early strength concrete
  • Prefabricated / prestressed concrete
  • High slump concrete
  • High-performance concrete
  • Low water-cement ratio
  • Ready-mixed concrete
  • Self-consolidating concrete (SCC)
  • Plane and mass concrete
  • Precast concrete, pipe pile concrete, segment concrete, etc.

Features & Advantages:

  • Good compatibility with other types of polycarboxylate superplasticizer and can be used in any proportion
  • No effect on solidification time, improving the strength and durability of hardened concrete
  • Wide adaptability to different types of cement and various admixtures
  • Excellent slump retention, fluidity, and workability to improve air consistency
  • Green, environmentally friendly, non-toxic and harmless

Usage:

The dosage of the early strength polycarboxylate superplasticizer is generally 0.3%-1.5% of the cementitious material and can be combined with other types of polycarboxylate superplasticizer, retarder, defoaming agent, air entraining agent, etc. The compounding is used to make the concrete workability better. The dosage should be optimized by trail by used actual building materials to satisfy the project needs.

Package & Storage:

It can be transported, sealed and stored in 200 kg drum or 1000 kg IBC tank. It must avoid rain, water leakage, debris or water evaporation. The storage period in sealed original packaging without sunlight can reach one year at 0~35°C. If you have any other questions, please contact us in time.
