A polycarboxylate ether-based Superplasticizer, Master Glenium 7500, made by Badische Anilino und Soda Fabrik (BASF), was used as the water reducing admixture in the preparation of the CPB. It is widely used in the backfill construction industries for the improvement of workability and/or flowability.

common, this puts higher requirements on the performance of polycarboxylate superplasticizer[5-6]. At present, the water reducing agent on the market has early bleeding due to the high water-reducing rate, and the stagnation of the stagnation of the stagnation agent requires the

amount of superplasticizer is usually increased to maintain the working performance of the concrete and make the concrete have good fluidity. However, the increase of the dosage of water-reducing agent can easily lead to the segregation and bleeding of concrete, and reduce the compressive strength of concrete.
The study on polycarboxylate superplasticizer with
The migration ability of water-reducing agents and other molecules in the system has been further explored. The diffusion coefficient of three water reducer molecules decreases in the following
- What is polycarboxylate superplasticizer?
- Polycarboxylate superplasticizer (PCE), the third generation of high-performance water reducer (water reducing admixture), follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
- 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.
- What are water reducers & retarders?
- Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture.
- What are water reducing admixtures?
- Our water reducing admixtures are formulated to enhance the workability and strength of concrete by minimizing the water content required in the mix. These additives disperse and lubricate cement particles, leading to improved consistency and easier placement while maintaining the desired performance characteristics.
- What is a high range water reducer admixture?
- Superplasticizers (High Range Water reducer) ASTM C494 Type F and Type G, High Range Water Reducer (HRWR) and retarding admixtures are used to reduce the amount of water by 12% to 30% while maintaining a certain level of consistency and workability (typically from 75 mm to 200 mm) and to increase workability for reduction in w/cm ratio.
- What are the different types of superplasticizers?
- There are four types of superplasticizers: sulfonated melamine, sulfonated naphthalene, modified lignosulfonates and a combination of high dosages of water reducing and accelerating admixtures. Commonly used are melamine based and naphthalene based superplasticizers.
