Lushnirova N. Cast high-strength concrete with polyfunctional modifier admixture on the basis of superplasticizer and metakaolin

Object – cement and concrete mixes with superplasticizer and metakaolin. The goal has been to develop the compositions of high-workability high-strength cement concrete with polyfunctional modifier. The methods – kinetics of electric current and ultrasound waves, porosimetry, computational experiment. The influence of the additive on water demand and structure formation has been studied, the positive influence on plasticization of mixes and concrete strength increase has been established. Proportioning the mixes of specified workability and compression strength at minimal cost of concrete presents the novelty. The results were applied when producing a batch of concrete with polyfunctional modifier. Applications – high-workability high-strength concretes.
