Absorption behavior of polycarboxylate superplasticizer with
Polycarboxylate (PCE) is a high performance superplasticizer for modern concrete. With the high quality sand becoming precious, more and more low quality sands are used in concrete. However, low quality sands generally contain a relatively high content of montmorillonite (MMT), which could seriously reduce the efficiency of PCE.
The influence of type and combination of polycarboxylate
The chemical admixture used in this study were two commercial grade methoxy polyethylene glycols (MPEG) and isoprenyl polyethylene glycols (TPEG) type of PCE based superplasticizer as high range water reducing admixture for HPSCC fabrication. They are namely PCE-M (MPEG) and PCE-T (TPEG) PCE superplasticizer respectively.
The Influence of Type and Combination of Polycarboxylate
The chemical admixture used in this study were two commercial grade methoxy polyethylene glycols (MPEG) and isoprenyl polyethylene glycols (TPEG) type of PCE based superplasticizer adopted as high range water reducing admixture for SCC production. They are namely WP30 (MPEG) and ZM-1 (TPEG), with solid content of 40% and 20%, respectively.
Preparation and Properties of Anti-mud and Viscosity
In this paper, a small amount of 2-Capped1-Phoshate Easter containing olefin functional group was introduced into the polycarboxylate superplasticizer molecule by free radical reaction, which...
TPEG – Murrun Environmental Technology Additives
描述. Inquiry. TPEG is the raw materials to produce polycarboxylate supeplasticizer with verygood slump retaining performance. Which is widely used in premix ofcommon concrete, gushing concrete, hydro concrete, also suitable for engineering projects under various weathers and primarily for usingin hot climate area. Properties and Uses:
- What is TPEG used for?
- TPEG is suitable for synthesizing polycarboxylate water-reducing agents with larger relative molecular weights, which is more conducive to maintaining good fluidity of concrete. It is the primary raw material for slump-preserving polycarboxylate water-reducing agents.
- What is polycarboxylate superplasticizer?
- Polycarboxylate Superplasticizer is the third generation superplasticizer based on calcium lignosulphonate and naphthalene sulfonate. The product is a free flowing, spray-dried powder which is improved by a special powder spraying dry technology. Its comprehensive property indexes are excellent.
- What are the advantages of TPEG/hpeg?
- 1.TPEG/ HPEG have good solubility in water. 2.TPEG/ HPEG adopts high active catalyst and special synthesis process, characterized by narrow molecular weight distribution, low polyethylene glycol content and high retention rate of double bonds. It obviously increases the reactivity of polymerization and raises the product yield.
- What is TPEG water reducing agent?
- The water reducing agent made of TPEG has a small slump loss and maintains a slump of ≥190 mm. The water reducing agent made of TPEG is green and environmentally friendly, with a chloride ion content of no more than 0.1%, and complies with ISO 14000 international environmental management standards.
- What is the shelf life of TPEG monomer?
- Shelf life: The shelf life of TPEG monomer is generally one year under specified storage and transportation conditions. Product Quality: The water reducing agent made of TPEG has the characteristics of early strength and high strength.
- What is TPEG / hpeg 2400?
- Brief guide : As a universal powder polycarboxylate superplasticizer, TPEG / HPEG 2400 has excellent formula adaptability and can be applied to various mortar formulations with different cementitious formulations, and gives mortar products with their excellent properties.
