▎ 摘　　要

NOVELTY - Composite concrete, comprises 600-900 pts. wt. cement, 70-100 pts. wt. silicon ash, 150-300 pts. wt. quartz powder, 800-1200 pts. wt. quartz sand, 6-15 pts. wt. water reducing agent, 1.0-2.0 wt.% steel fiber and 0.1-0.8 wt.% carbon nanomaterials. The carbon nano-material comprises multi-layer grapheme at least one layer of graphene, reducing and oxidizing graphene carbon nano- fiber, multi-wall carbon nano-tube and/or surface wall carbon nano-tube. The surface-wall carbon nano-tube is graphitized multi-wall carbon nano-tube or nickel plated multi-wall carbon nano-tube. The water reducing agent is polycarboxylic acid water reducing agent. USE - The composite concrete is useful in building material and infrastructure. ADVANTAGE - The concrete: has self-sensing effect, high toughness, strength, anti-deformation ability, ultra-high performance, strong conductivity, piezoresistive sensitivity and pressure resistance stability; and the method is simple, easy to operate and implement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of composite concrete
