The influence of mineral admixtures on rheology
The basic influence trends of mineral admixtures on rheology of mortars with polycarboxylate and polyeter superplasticizers are presented. It is concluded that the compatibility of cement and superplasticizer system should be selected taking into account presence and estimated dosage of given mineral admixture.
OPTIMIZATION OF SCC MIXTURES INCORPORATING A POLYCARBOXYLATE
1. Introduction The optimization of superplasticizers used for self-compacting concrete (SCC) is essential to formulate successful and robust SCC mixtures [1-8].
Optimization of SCC mixtures incorporating a polycarboxylate
A few of polycarboxylate-based super plasticizers intended for the production of self-compacting concrete are available in Saudi Arabia construction market, such as Glenium.
Sika ViscoCrete-225 P | High Range Water Reducing Powder
HIGH RANGE WATER REDUCING POWDERED SUPERPLASTICIZER Sika ViscoCrete-225 P is a third generation high range water reducing and superplasticizing powder admixture for use in concrete and mortar. It is based on Sika’s patented ‘ViscoCrete’ polycarboxylate polymer technology.
Polycarboxylate Superplasticizer (PCE) For Concrete
Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture. It is a water reducing agent with excellent performance that integrates water reduction, slump protection, reinforcement, shrinkage and environmental protection.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture.
- What are the advantages of polycarboxylate based superplasticizer?
- Low dosage and high water reduction rate. The water reduction rate of polycarboxylate based superplasticizer can be as high as 45%, which can be used to prepare high-strength and high-performance concrete. Small loss when slump is light.
- What is a polycarboxylate ether superplasticizer?
- The polycarboxylate ether superplasticizer is an additive commonly used in concrete engineering and has a wide range of applications. The PCE based admixture can significantly reduce the amount of cement and improve the fluidity and pumpability of concrete while ensuring the strength and durability of concrete.
- Can polycarboxylate based superplasticizer improve the crack resistance of concrete?
- The polycarboxylate based superplasticizer can improve the crack resistance of concrete. After adding an appropriate amount of water reducing agent in concrete, the internal structure of the concrete can be improved and the contraction and cracking of concrete can be reduced.
- Does polycarboxylate water reducer reduce cement dosage?
- Save cement dosage. Polycarboxylate water reducer can significantly reduce the amount of cement dosage of concrete and save costs. By adding an appropriate amount of water reducing agent, you can reduce the amount of cement without reducing the strength of the concrete to achieve the purpose of saving costs.
- What is PCE concrete admixture?
- PCE concrete admixture is a kind of high-efficiency water reducer that can be mainly used for concrete. Adding the amount of pce admixture into concrete, the slump and expansion loss of the concrete are small, the fluidity is large, and the water retention, cohesiveness, and climate adaptability all perform well.
