| titleOfInvention | Mixtures for heavy concrete production |
| abstract | (57) [Summary] [Purpose] It is an object of the present invention to obtain a mixture for producing heavy concrete, which has a high specific gravity and excellent chemical and mechanical properties. [Structure] A coarse aggregate composed of hematite and / or crushed stone containing ferric oxide as a main component in a total amount of 70 to 85% by weight, and hematite, sand iron and sand similarly containing ferric oxide as a main component. Of these, at least two types of fine aggregate are used, and the cement paste has a water-cement ratio of 0.4 to 0.6 and a cement paste of 15 to 30 wt% And a high-performance water reducing agent as an admixture is added to the cement in an amount of 0.1% to 2%. The added high-performance water-reducing agent improves the fluidity of concrete by ball bearing-like air entrainment and prevents separation of high-density aggregates as much as possible, making it possible to obtain homogeneous and high-strength heavy concrete. It is a thing. |
