The role of superplasticizers in the formation of self-compacting concrete strength
The use of self-compacting concrete can significantly improve the quality of concrete products. To make it, you need to choose the right superplasticizer, which will provide a low water-cement ratio and good mobility. Especially important is the optimum dosage of plasticizer, as self-compacting concrete has a number of fine features, leading him to the sensitive bundle recipe: increased consumption of cement increased consumption of plasticizers, reduced consumption of filler, excellent rheological properties. This article discusses the effect of consumption of cement and superplasticizer on the properties of fine-grained concrete mix, such as density and air entrainment, and on the kinetics of a set of concrete strength. The possibility of increasing the strength characteristics of self-compacting concrete sand by choosing the type of superplasticizer. The regularities of time spreading of self-compacting concrete on the dosage of the superplasticizer.
