Strength Enhancement of Concrete with a Plasticizer on the Basis of Nano-Structured Carbon

Technological properties of concrete mixtures modified with a plasticizer on the basis of nano-structured carbon are studied. The effect of the additive on the basic properties of heavy concrete of C25/30 class is investigated. The results of the research indicating the active participation of carbon nano-tubes, increasing the performance characteristics of concrete, as well as the possibility of reducing the amount of cement introduced to 10% are presented. The plasticizer has properties that accelerate the rate of strength gain, which makes it possible to solve the problems of early stripping without the use of steaming, and also increases the final strength of the product by an average of 30%. The tests conducted have shown that the additive under consideration makes it possible to solve the problems of a set of strength characteristics faster saving electricity. The plasticizer on the basis of nano-structured carbon can find the use in the ready mixtures (with high level of mobility, frost resistance, and water proofing) to stiff heavy concretes.
