More Information
Summary:The invention discloses a natural tuff ultra-high performance concrete and a preparation method thereof. The concrete is prepared from the following components in parts by weight: 100 to 250 parts ofnatural tuff, 100 to 250 parts of limestone powder, 600 to 900 parts of cement, 100 to 200 parts of silica fume, 900 to 1200 parts of fine aggregate, 120 to 200 parts of steel fibers, 8 to 10 parts ofan additive and 160 to 190 parts of water. Based on the characteristics of the chemical components of natural tuff, the mineral additives activate each other through fine grinding; the activity of natural tuff is fully utilized to form a new ultra-high performance concrete cementing material system, the wastes are fully utilized, meanwhile, the strength and the volume stability of the ultra-highperformance concrete are improved, the raw material source of the ultra-high performance concrete is broadened, the cost of the ultra-high performance concrete is reduced, and the promotion and the application of the ultra-high
