Preparation process of high-strength wear-resistant concrete
The invention discloses a preparation process of high-strength wear-resistant concrete. The concrete is prepared from the following components in parts by weight: 300 to 400 parts of Portland cement,500 to 900 parts of fine aggregate, 950 to 1250 parts of coarse aggregate, 180 to 190 parts of water, 20 to 40 parts of silica powder, 50 to 80 parts of epoxy resin, 5 to 12 parts of steel fiber, 1 to4 parts of a water reducing agent, 6 to 12 parts of an accelerator, 0.15 to 0.6 part of an air entraining agent and 40 to 65 parts of metakaolin. The structure of the concrete is scientific and reasonable; the preparation method is safe and convenient to use; and the prepared concrete is high in strength and not prone to damage during heavy pressing and collision, the overall strength of the prepared concrete during use is improved, the wear resistance of the concrete is improved, and the setting rate of the concrete is increased, so the market competitiveness of the prepared concrete is improved.
本发明公开了一种高强度耐磨混凝土的制备工艺，所述混凝土由下述组分按重量份组成：硅酸盐水泥300‑400份、细骨料500‑900份、粗骨料950‑1250份、水180‑190份、硅微粉20‑40份、环氧树脂50‑80份、钢纤维5‑12份、减水剂1‑4份、速凝剂6‑12份、引气剂0.15‑0.6份、偏高岭土40‑65份，本发明结构科学合理，使用安全方便，制备得出的混凝土强度较高，制备得出的混凝土不易在重压和碰撞时出现损伤，提高了制备出混凝土使用时的整体强度，并且提高了混凝土的耐磨程度，加快了混凝土的凝结速率，从而提高了制备出混凝土的市场竞争力。
