Novel wear-resistant concrete for pavement engineering and preparation method of novel wear-resistant concrete
The invention discloses novel wear-resistant concrete for pavement engineering and a preparation method of the novel wear-resistant concrete, ingredients comprise cement, water, sand, pebbles and iron powder, the iron powder is processed and manufactured by waste brake shoe friction parts, and every 100 parts of mixture of the ingredients comprise the following raw materials in parts by weight: 20.7-21 parts of cement, 23.8-27.6 parts of sand, 42.3-43 parts of pebbles, 2.8-4.4 parts of iron powder and the balance of water; by doping the iron powder, a transitional buffer area can be formed on the contact surface of cement paste and aggregate, separation between the aggregate and cement mortar is slowed down, the interface bonding strength of the aggregate and the mortar is improved, the defects of the concrete are reduced, and therefore the strength and wear resistance of the concrete are improved; the environment-friendly and economic values are relatively high.
本发明公开了一种用于路面工程的新型耐磨混凝土及其制备方法，配料包括水泥、水、砂子、石子及铁粉，所述铁粉为废弃的闸瓦摩擦件加工制作，配料的每100份混合物中包含以下重量份的原料：水泥为20.7～21份，砂子23.8～27.6份，石子42.3～43份，铁粉2.8～4.4份，其余为水；铁粉的掺入能够在水泥净浆与骨料接触面形成过渡的缓冲区，减缓骨料与水泥砂浆之间的离析，提高骨料与砂浆的界面结合强度，减少混凝土缺陷，从而提高混凝土强度及耐磨性，并且，所使用的铁粉为废弃的闸瓦摩擦件加工制作，具有较强的环保和经济价值。
