Research in the Effect of Water-Cement Ratio on Strength of Fine Concretes with a Filler of Granulated Blast Furnace Slag

An original approach to the design of multi-component cement mixtures with fine aggregates with high water demand is presented. For different compositions of mixtures, the compressive strength of fine concrete samples was studied depending on the mixing factors. The shares of components in the mixture of granulated blast furnace slag, sand, water at a constant consumption of cement and modifying additives were considered as influencing factors: On the basis of the laboratory experiment data, mathematical models are constructed and with their help the dependences of the compressive strength of fine concrete on the slag/water ratio, as well as the optimal ratios in the filler–water system are established. The specific values of water-solid ratio for cement mixtures, at which the strength of the samples increases by up to 35%, as well as the optimal ratio of components making it possible to obtain fine concrete with high strength of up to 30 MPa are revealed
