Polymeric superplasticizers based on polycarboxylates for ready-mixed concrete:
current state of the art (in English)
Polimery 2016, No 7-8, 474
Chemical admixtures are one of the basic components of the contemporary concrete. The most important 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 derivatives. The state of the art in the range of polycarboxylate admixtures for concrete is presented in the paper. The methods of synthesis and modification of carboxylic polymers are characterized and the mechanism of action of polycarboxylate superplasticizers is described. The influence of the chemical structure of polycarboxylates on the consistence of the concrete mix, as well as the prognosis of the superplasticizers development is also presented.
