polycarboxylate superplasticizer with high water retention. The performance test results show that the product has high water-reducing ratio and better workability when applied to concrete, which can effectively retain the moisture in concrete and ensure the stability of concrete fluidity. 1. Introduction
A polycarboxylate as a superplasticizer for montmorillonite
A novel polycarboxylate superplasticizer (PCE) with a long polyoxyethylene (PEO) chain and a terminal carboxylic group was synthesized from a modified polyether (SAE-IPEG) to increase its performance in cement. The molecular structure of the PCE was characterized by infrared spectroscopy and 1 H nuclear magnetic resonance (NMR) spectroscopy
Sika ViscoCrete-3110 | PCE based Super-plasticizers
Sika ViscoCrete-3110 is a third generation polycarboxylate based superplasticizer for concrete. It has been particularly developed for use in ready mixed concrete to give extended slump retention and high strength development of normal grade concrete mixes.

Effect of superplasticizers on the rheological properties
This paper explores the influence of superplasticizer dosage, superplasticizer family and mineral admixture dosage on the rheological behavior of cement paste. For this purpose cement pastes were prepared at a water cement ratio of 0.37 using OPC and different percentage of fly ash (15, 25, 35) and different dosages of superplasticizer (one
- 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.
- What is polycarboxylate superplasticizer (PCE)?
- As one important auxiliary, superplasticizers have attracted lots of attention in the concrete and building materials field. Specially, polycarboxylate superplasticizer (PCE) has been widely applied due to its relatively low doping amount, high water reducing rate and environmental friendliness property.
- 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.
- 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 a superplasticizer?
- Our premium superplasticizers are designed to significantly improve the workability and durability of your concrete mixes. By reducing water content without compromising strength, these additives ensure optimal flowability and ease of placement, making them ideal for high-performance concrete applications.
