NOVELTY - A cement concrete comprises 350-400 kg cement clinker, 11-20 kg gypsum, 130-170 kg admixture, 0.1-0.25 kg borax, 1950-2100 kg aggregate, 1.5-2.5 kg urea, 1-2 kg graphene, 10-15 kg fiber and 190-230 kg water, per cubic concrete. The cement clinker is composed of 50-65 pts. wt. marine Portland cement clinker, 20-35 pts. wt. sulfoaluminate cement clinker and 10-20 pts. wt. belite-barium sulfoaluminate cement clinker. The admixture is composed of raw materials comprised of 20-35 pts. wt. fly ash, 50-65 pts. wt. steel slag and 15-30 pts. wt. barium slag. USE - Cement concrete for nuclear power engineering. ADVANTAGE - The cement concrete has high apparent density, high content of heavy elements and light elements, excellent thermal stability, high thermal conductivity, excellent thermal expansion and shrinkage properties.
