The influence of finely ground zeolite-containing rock on the properties of fine-grained concrete mixtures is considered and its interaction with cement. Defined optimal dosage of the zeolite-containing rock, which increases strength under bending and compression.
Keywords: fine-grained concrete, fine-grained concrete, zeolite-containing rock, finely ground filler, mineral additive
The effectiveness of the use of superplasticizers of various chemical bases of the MC-Bauchemie Group: PowerFlow 7951, Muraplast FK 49 and Centrament N 10 was studied in concrete. The quantitative influence of the superplasticizer on the properties of cement binder and concrete was studied. Based on the obtained research results, we recommend the costs of additives for the production of heavy concrete.
