Tests on superplasticizing admixtures for concrete

Magazine of Concrete Research, 1983
Synopsis The performance in concrete of nine commercial superplasticizing admixtures has been examined by using a particular test procedure to evaluate their performance and to provide comparative data on their effects. All the superplasticizers were observed to have an appreciable fluidifying action in fresh concrete so that, under appropriate ...

A New Type of Colorless Superplasticizer

Applied Mechanics and Materials, 2011
This paper studies industrial acetone, p-amino benzene sulfonate as raw materials, developed a colorless superplasticizer and the test on its liquidity, solid content, setting time, and the performance of concrete. Finally got this colorless superplasticizer for decorative concrete.

Working mechanism of post-acting polycarboxylate superplasticizers containing acrylate segments

, 2018
Acrylate-containing polycarboxylate superplasticizers were synthesized by copolymerizing acrylic acid, α-methallyl-ω-methoxy poly(ethylene glycol) ether, and acrylic esters [hydroxyethyl acrylate (HEA) or hydroxypropyl acrylate (HPA)].

Compatibility of polycarboxylate superplasticizers with cements

2006
Superplasticizers are nowadays often used for ready-mix concrete, but also for other purposes in concrete technology. In most cases, without adding a superplasticizer to concrete, it is not possible to achieve the desired properties of fresh and hardened concrete. Properties of fresh concrete, such as slump, slump loss with time, segregation, bleeding,
