AbstractAbout AuthorsReferences
To reduce material and energy consumption of concrete products manufacturing, it is necessary to develop the formulation and introduce technologies of production of multi-component fine concretes with the use of industrial waste. The introduction of steelmaking slag and micro-silica in cement mix makes it possible to optimize the granulometric composition of fillers, and, in case of using the plasticizing additive, to improve the structure of composite material. Results of the experimental determination of compressive strength, water absorption, density of the samples of the cement composite material depending on the percentages of components are presented. In case of increasing the content of steelmaking slag in the composition of a fine filler by 0–30%, the increase in the strength of samples by 22% is observed. The introduction of 20% of micro-silica and addition of the superplasticizer C-3 to 3% by weight of the binder positively influence on the strength characteristics. Formulations and strength characteristics of fine concrete compositions suitable for the manufacture of wall blocks are presented.
