Effect of Naphthalene-Based Superplasticizer and Polycarboxylic
In order to study what the effect of superplasticizers on the setting time, fluidity and compressive strength of calcium sulfoaluminate cement (CSA) a naphthalene-based superplasticizer (BNS) and
Effect of Functional Polycarboxylic Acid Superplasticizers on
Modern engineering practices require that polycarboxylic acid high-performance superplasticizers have good adaptability to various environments and materials, which indicates the importance of
Plasticizers - Chemical Economics Handbook (CEH) | S&P Global - IHS Markit
Flexible PVC (and thus plasticizers) is found in the following applications: construction (flooring, wall coverings), electrical (wire and cable jacketing), consumer goods (toys, footwear, etc.), packaging, transportation (inside and outside of vehicles), furnishings, and medical uses (tubing, blood bags).
Comparative study of Conplast SP 430 and Polycarboxylic Ether
Polyvinyl alcohol is a high resistance nonreactive material. It will not oxidize when exposed to aggressive whether conditions and having good affinity with cement. Polyvinyl alcohol fibre of size...
Polycarboxylic Ether Based Superplasticizers in Eastern Asia
3.4. Super-Plasticizer To achieve high homogeneity and produce the self-compacting concrete, hyperplast PC200, which is a super plasticizing admixture, based on polycarboxylic ether polymers with long chains has been used. The typical properties of hyperplast PC200 (according to the manufacturer editions) are shown in Table 3.
- What are structural changes in polycarboxylate superplasticizer (PCE)?
- Structural modifications in the molecular scale of polycarboxylate superplasticizer (PCE) would lead to changes in properties of dispersion and water retention as well as enhancement in the compatibility of Portland cement and so on.
- What is a polycarboxylate superplasticizer?
- In contrast to other polycarboxylate superplasticizer such as sodium bisulfite and tonalite, polycarboxylate molecules generated through the REDOX system of hydrogen peroxide and ammonium persulfate Vc exhibit a compact high monomer conversion and molecular weight distribution.
- What is polycarboxylic ether superplasticizer?
- Introduction Generally, polycarboxylic ether superplasticizer (PCEs) have excellent properties of high water reduction and high slump retention capacity, and they are widely used in engineering , , , . In the synthesis of PCEs, the types of macromonomers are extremely important.
- Does polycarboxylic superplasticizer affect dispersion and water retention?
- Authors to whom correspondence should be addressed. The molecular-scale structural changes in polycarboxylic superplasticizer (PCE) can influence dispersion and water retention. Polycarboxylate superplasticizer, synthesized using different methods, may alter dispersion and water-reducing effects.
- How are amide-structural polycarboxylate superplasticizers produced?
- In another study by Liu et al. , amide-structural polycarboxylate superplasticizers (amide-PCEs) were produced by amidation reaction between polyacrylic acid (PAA) and amino-terminated methoxy polyethylene glycol (amino-PEG) at 130–150°C.
- What is ultra-early strength type polycarboxylate superplasticizer?
- In this study, a ultra-early strength type polycarboxylate superplasticizer (ES) was synthesized successfully by a design molecule structure such as introducting ultra long polyoxyethlene side chains, functional monomer (2-acrylamide-2-methylpropanesulfonic acid), and cationic monomer (Methacrylatoethyl trimethyl ammonium chloride) composition.
