High-strength concrete capable of effectively reducing crack defects and preparation method thereof
The invention discloses high-strength concrete capable of effectively reducing crack defects. The high-strength concrete is prepared from the following raw materials in parts by weight: 10-15 parts of cement, 50-75 parts of pebbles, 65-90 parts of sand, 15-25 parts of water, 20-30 parts of a water reducing agent, 15-20 parts of modified zeolite powder, 15-20 parts of limestone powder and 10-25 parts of epoxy resin. The modified zeolite powder is added into the raw materials, so that the workability of the concrete material can be improved, and the strength of the concrete can be improved; by adding the limestone powder into the raw materials, the discharge of bubbles in concrete can be accelerated, so that the probability that the bubbles appear on the surface of a component is effectively reduced, and by adding the limestone powder, after the concrete is hardened, moisture absorbed by the limestone powder can be slowly released and is used for compensating water for later hydration of the concrete, so that the shrinkage of the concrete is reduced, and the durability is good; the epoxy resin is added into the raw materials, so that the strength and hardness can be improved, the bonding strength is improved, the crack defect is reduced, and the material is more durable and firmer.
本发明公开了一种可有效降低裂纹缺陷的高强度混凝土，包括以下重量份原料：水泥10‑15份、石子50‑75份、砂65‑90份、水15‑25份、减水剂20‑30份、改性沸石粉15‑20份、石灰石粉15‑20份、环氧树脂10‑25份。本发明通过在原料中加入改性沸石粉，能够改善混凝土物料的和易性以及能够提高混凝土强度；通过在原料中加入石灰石粉可加速混凝土中气泡的排出，从而有效地降低构件表面气泡出现的概率，且加入石灰石粉，在混凝土硬化后，被石粉吸收的水分会慢慢释放，用于补偿混凝土后期水化用水，从而减少了混凝的收缩，耐久性好；通过在原料中加入环氧树脂，可以提高强度和硬度，且提高了粘结强度，降低裂纹缺陷，使得其更加耐久和牢固。
