Investigation of Fine-Grained Concrete Properties with a Mixed Binder and Various Fillers
The article focuses on investigating the influence of various fillers on the physicomechanical characteristics of fine-grained concrete modified with a mixed binder. River sand and lithoid pumice were chosen as fillers for the study. Compositions of aerated concrete with different fillers based on mixed or modified binders were developed, and their properties were experimentally studied. Superplasticizers, micro silica, and lime were used to modify the binder, which was introduced in varying quantities. The results obtained due to the type of fillers used are as follows: the compressive strength of the mortar made using of river sand, compared to the sample with the reference sample, increased by 27.5% at the age of 28 days, and by 12.1% in the case of lithoid pumice. The effect of lime definitely leads to an increase in the density of cement stone with heavy aggregate, and with light aggregate, the density decreases, and as a result, no significant increase in strength is observed.
