Abstract

The invention discloses a nanometer modified cement-based wear-resistant material which is made of following raw materials, by weight, 15-35% of sulfate aluminum cement, 25%-45% of ordinary acid salt cement, 10-20% of quartz sand, 30-45% of corundum and 5-10% of barium sulfate superfine powder. Polycarboxylate water reducer accounts for 0.2-1.5% of the total quantity of the sulfate aluminum cement and the ordinary acid salt cement, and expansion components formed by composition of lime expansion agent and gypsum aluminate expansion agent account for 5-10% of the total quantity of the sulfate aluminum cement and the ordinary acid salt cement. Cement is taken as main gelling materials, and wear-resistant components which comprise reasonable graded wear-resistant aggregate with high Moh's hardness, necessary chemical additives and special wear-resistant materials prepared by industrial production play a role in assisting. The nanometer modified cement-based wear-resistant material overcomes technological defects of poor wear resistance, poor impact resistance, bad integrity and the like of conventional wear-resistant materials.

Description

technical field [0001] The invention relates to the technical field of concrete structures, and more specifically relates to a nano-modified cement-based wear-resistant material. Background technique [0002] At present, in the heating furnace iron sheet ditch, blast furnace slag washing ditch, hopper and concrete structures with wear-resistant and heat-resistant requirements in the domestic industry, the treatment of the wear-resistant concrete surface layer is mainly used for iron chip concrete and masonry cast stones. Mainly. [0003] Although the wear resistance of cast stone blocks is very good, it requires high concrete foundation during construction, it is difficult to bond and install, the construction speed is slow, and the high temperature impact resistance is poor. The biggest disadvantage is that its integrity is poor and the cost is high. ; Although the iron filing concrete has good integrity, its wear resistance is poor, and the source of materials is relative...
