How do plasticizer and superplasticizer differ?

Jul 23, 2018 · Concrete plasticizer which is commonly known as water reducing admixture amongst professionals is used for improving workability of concrete. It either increases workability of freshly mixed concrete without increasing the water cement ratio.

Effects of Superplasticizer, Retarding Agent, and Silica Fume

The effect of slump (or superplasticizer dosage) on the surface permeability of the HPC decreased as compressive strength increased. The use of a retarding agent in HPC without silica fume increased the air permeability of the surface concrete. This effect is particularly important for the concrete containing a high dosage of superplasticizer.

EP2218686A1 - Composition comprising cerium(IV) for

A composition, comprising: (a) an oxidizing agent comprising cerium having a cerium oxidation state of +4 to oxidize arsenic having a +3 oxidation state to arsenic having a +5 oxidation state; and (b) a rare earth-containing precipitating agent comprising a rare earth having a rare earth oxidation state of +3 to precipitate, from an aqueous solution, the arsenic in the +5 oxidation state.

The Effect of Superplasticizer on Strength and Chloride

The effect of superplasticizer on the mechanical property and chloride permeability of concrete containing GGBFS is investigated in this paper. Compressive and rapid chloride-ion diffusion tests were conducted to determine the axial compressive and chloride-ion diffusion coefficients of GGBFS modified concrete.

Effect of superplasticizer dosages on compressive strength of

compressive strength of self- compacting concrete. Keywords: Self-compacting concrete, superplasticizer, compressive strength. 1. Introduction Self-compacting concrete (SCC), requires no consolidation work at site or concrete plants. The SCC was first developed in Japan to improve the reliability and uniformity of concrete in 1988 (Okamura, 1999).

polycarboxylate ether superplasticizer,carboxylic acid

TH511 is polycarboxylate ether-based superplasticizer (PCE). It is developed for applications in the ready mixed concretes. Its addition to concrete or mortar allows the huge reduction of the water to cement ratio, drastically improves the workability and performance of the mixture, and enables the production of self-consolidating concrete and high performance concrete.

An Analysis of the Increased Demand of superplasticizer

The superplasticizer industry has a high degree of dispersion, upstream petrochemicals, and downstream infrastructure real estate: superplasticizer is an indispensable component of concrete. Although the proportion is low, it can significantly improve the performance of concrete, mainly including high-efficiency water reducer and high ...

Polymeric superplasticizers based on polycarboxylates for

portant admixtures are superplasticizers, i.e. the modifiers which allow for high-range reducing of the water content in the concrete mix. The most effective superplasticizers are based on polycarboxylates and their de-rivatives. The state of the art in the range of polycarboxylate admixtures for concrete is presented in the paper.
