【 摘 要 】

This paper presents the results of the complex modifying additive's effect consisting of a dispersed inert additive (diopside) and an active mineral additive (microsilica) and plasticizer on the strength properties and salt resistance of fine-grained concrete. It is shown that reducing the particle size of the inert mineral additive decreases its amount required to provide maximum curing of concrete specimens. The optimal ratio of microsilica, diopside, and plasticizer required to achieve maximum performance characteristics (compressive and bending strengths and, salt resistance) is determined.
