High-strength pavement concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses high-strength pavement concrete and a preparation method thereof. The high-strength pavement concrete comprises cement, mineral powder, fly ash, sand, stone, a water reducing agent, a synergist, di-tert-butyl dicarbonate, sodium dichloroisocyanurate and water. The preparation method comprises the following steps: 01) uniformly mixing cement and water to form cement slurry; 02) adding di-tert-butyl dicarbonate, sodium dichloroisocyanurate and a water reducing agent into the cement slurry, and uniformly mixing to form a premixed material; 03), adding mineral powder, fly ash, sand and stone into the premixed material, and uniformly mixing to form high-strength pavement concrete slurry; and 04) pouring the high-strength pavement concrete slurry into a mold, maintaining and curing to form the high-strength pavement concrete. The high-strength pavement concrete disclosed by the invention can be used for pouring pavements and has the advantage of high compressive strength, and in addition, the preparation method disclosed by the invention has the advantage of better quality of a concrete mixture.
本申请涉及混凝土领域，具体公开了一种高强路面混凝土及其制备方法。高强路面混凝土及其制备方法包括水泥、矿粉、粉煤灰、砂、石、减水剂、增效剂、二碳酸二叔丁酯、二氯异氰尿酸钠、水。其制备方法为：步骤01），将水泥和水混合均匀形成水泥浆液；步骤02），在水泥浆液中加入二碳酸二叔丁酯、二氯异氰尿酸钠、减水剂，混合均匀形成预拌料；步骤03），在预拌料中加入矿粉、粉煤灰、砂、石，混合均匀，形成高强路面混凝土浆液；步骤04），强高强路面混凝土浆液浇筑至模具中，养护，固化形成高强路面混凝土。本申请的高强路面混凝土可用于浇筑路面，其具有抗压强度高的优点；另外，本申请的制备方法具有混凝土拌和料质量较佳的优点。
