High-strength concrete slurry coating process
The invention relates to the field of concrete, and particularly discloses a high-strength concrete slurry coating process, which comprises the following steps: 1, mixing water and an additive to obtain a preparatory solution; 2, premixing sand for 10-15 seconds at a rotating speed of 20-30 revolutions per minute to obtain a homogeneous sand material; 3, adding cement, a mineral powder mixture andsilicon powder into the homogeneous sand material according to a water-binder ratio of 0.26-0.28, and stirring for 20-35 seconds to obtain a dry mortar mixture; 4, adding the preparatory solution into the dry mortar mixture, and stirring for 50-60 seconds to obtain a wet mortar mixture; and 5, stirring 940-960 parts of stone and the wet mortar mixture for 120 seconds to obtain high-strength concrete, wherein the additive comprises the following components in parts by weight: 11-16 parts of a polycarboxylic acid high-performance water reducing agent, 1.5-2 parts of polyvinyl carbazole, and 0.6-1.1 parts of sodium D-gluconate. The concrete prepared by the process has the advantages of high strength and good wear resistance.
本申请涉及混凝土领域，具体公开了一种高强混凝土裹浆工艺。裹浆工艺包括：步骤1，将水、添加剂混合，获得预备液；步骤2，将砂进行预拌10~15秒，转速20~30转/分钟，获得均质砂料；步骤3，将水泥、矿粉混合料、硅粉加入均质砂料，水胶比0.26~0.28，搅拌20~35秒，获得干砂浆混合物；步骤4，预备液投入干砂浆混合物，搅拌50~60秒，获得湿砂浆混合物；步骤5，将石940~960份与湿砂浆混合物搅拌120秒，获得高强混凝土；所述添加剂包括：聚羧酸高性能减水剂11~16份；聚乙烯咔唑1.5~2份；D‑葡萄糖酸钠0.6~1.1份。本申请的工艺制备的混凝土具有强度高且耐磨性好的优点。
