Structure-property relationships for polycarboxylate ether
2.8. Minislump test. Minislump tests were performed to determine the paste flowability, with and without the addition of SP. For these tests, pastes containing 0.1% of SP (relative to cement mass) were prepared with a w/c ratio of 0.38 by hand mixing for 180 s and subsequently poured into a mini cone with a bottom diameter of 30 mm, an upper diameter of 10 mm and height of 25 mm. Spread flow
Preparation and properties of allyl ether-based
Polycarboxylate ether (PCE) superplasticizer possesses outstanding characteristics, such as better slump adjustment, higher water reduction rate, and lower dosage. 1,2 It is a new type of superplasticizer commonly used in advanced concrete in recent years.

showed that when acid/ether mole ratio was 4.0/1, P dosage was 8% of TPEG, rotating speed was 800rpm and reaction temperature was 60℃, synthetic polycarboxylate superplasticizer had the best comprehensive performance. 1.Introduction The polycarboxylate superplasticizer is mainly a liquid product on the market currently[1].The factory
Preparing controlled low strength materials (CLSM) using
To satisfy engineering requirement, the contradiction between flowability and strength of very fine aggregates should be addressed. This paper examines the feasibility of preparing controlled low strength material (CLSM) using excavated waste soils, where polycarboxylate superplasticizer (PCE) is used to improve workability of the materials.

ET-PC polycarboxylate superplasticizer can greatly improve compactness, freeze-thaw resistance, carbonation resistance, elastic modulus and impermeability; reduce drying shrinkage and creep of concrete. (8) A stable performance, non-precipitation. Technology Data: Packaging and storage: Powder pack: woven fabric bag with plastic liner.
- 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 powder?
- Polycarboxylate Superplasticizer powder is a new generation pce based superplasticizer, which can be used as a superplasticizer and water-reducing agent for cement-based materials such as high performance concrete, dry mortar, waterproof mortar, self-leveling, grout and polyphenyl thermal mortar.
- Do Polycarboxylate ether/ester superplasticizers affect concrete performance?
- Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture.
- What is the best powder PCE superplasticizer for concrete?
- This powder pce superplasticiser will definitely meet your need. Polycarboxylate Superplasticizeris (PCE) powder, also called polycarboxylate ether superplasticizer, polycarboxylic ether based superplasticizers, is the best superplasticizer for concrete at present.
- What is et-PC polycarboxylate superplasticizer?
- ET-PC polycarboxylate superplasticizer can greatly improve compactness, freeze-thaw resistance, carbonation resistance, elastic modulus and impermeability; reduce drying shrinkage and creep of concrete.
