Research on Properties of High-Performance Cement Mortar
3.1. Analysis of the Workability on HPCM. As shown in Table 4, the factors affecting the workability, in the order of importance, are the polycarboxylate superplasticizer, the water-binder ratio, the accelerating admixture, the expansion admixture, the mineral powder, and the sand-binder ratio, and their weight ratios are 28.18%, 25.75%, 17.97%, 11.49%, 8.28%, and 7.69%, respectively.
Synthesis of lignin-grafted polycarboxylate superplasticizer
It is common that high-performance concrete is highly viscous, which is not conducive to transportation and pumping. In order to reduce the viscosity of fresh high-performance concrete, a lignin-based polycarboxylate superplasticizer (PCE-ACLx) was synthesized through a novel process and the structure was characterized by FTIR, 1 H NMR and GPC.
Synthesis of Modified Polycarboxylate and Its
The experimental results show that the synthesized polycarboxylate could be better dispersed. Adding silica fume can enhance the compressive strength of ultra-high performance concrete...
Synthesis and Performance Characterization of a Low
A low adsorption clay-resistant polycarboxylate superplasticizer (KN-PC) was synthesized using acrylic acid and isopentenol polyoxyethylene ether as the main reaction materials. The structural characterization and clay-resistant mechanism of the KN-PC were explored using Fourier transform infrared spectroscopy and X-ray diffraction, and the effect of the KN-PC on the performance of composite
Concrete Superplasticizer - High Range Water Reducer in Kingsun
The superplasticizer for concrete has the functions of high-efficiency water reduction, retardation, slump retention and reinforcement. This product has strong adaptability to cement, less dosage, and is easy to use. It is especially suitable for concrete projects that require high-efficiency water reduction and retardation.
- What is polycarboxylate superplasticizer powder?
- The main component is polycarboxylate, which is a fluid powder made by special drying technology. And its comprehensive indicators are excellent, green and pollution-free, so polycarboxylate superplasticizer powder is the high-performance environmentally friendly product.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate Superplasticizer (PCE) represents the latest innovation in concrete admixture technology. Unlike traditional superplasticizers, PCE offers unparalleled control over concrete's rheological properties, making it essential in the production of high-performance concrete.
- What are the advantages of polycarboxylate superplasticizer?
- (2) PC polycarboxylate superplasticizer has excellent water-reducing ability. can greatly reduce slump loss. (3) PC can significantly reduce 25% ~40% mixing water in concrete. (4) High strength enhancing ability. Better performance when used together mineral admixture. (5) No bleeding, anti-segregation, easy to pump and transport.
- Who makes polycarboxylate superplasticizers?
- As one of the most professional construction chemicals manufacturer in China, Kingsun has been committed to the research and production of polycarboxylate superplasticizers for more than 15 years. We have our own factory, the advanced production equipment and technology, and the annual output of PCE superplasticizers is up to 120,000 tons.
- What is a polycarboxylate superplastic?
- Polycarboxylate superplastics, also known as high-grade water reducers, they are chemicals that are used where well-dispersed particle suspensions are required. These polymers are used as dispersants to avoid particle aggregation to improve the flow characteristics or rheology of solid applications such as suspensions.
