Modified concrete and preparation method thereof
The invention provides modified concrete and a preparation method thereof, and belongs to the technical field of building materials, the modified concrete comprises the following components by weight: 400-500 parts of cement, 300-400 parts of modified waste glass fiber reinforced plastic fiber, 350-420 parts of coarse aggregate, 500-600 parts of fine aggregate, 50-80 parts of modified silica fume, 5-8 parts of a dispersant, and 800-1200 parts of mixing water; the glass fiber reinforced plastic waste is used for replacing part of gravel filler, waste recycling is achieved, the material cost is saved, and environment protection is facilitated; by modifying the waste glass fiber reinforced plastic fibers, the mechanical property of the concrete can be effectively improved, water permeation can be reduced, cracks generated in the freezing and thawing cycle process are reduced, and the anti-freezing property of the concrete is improved.
本发明提供了一种改性混凝土及其制备方法，属于建筑材料技术领域，所述改性混凝土包括如下重量份的组分：400‑500份水泥、300‑400份改性废弃玻璃钢纤维、350‑420份粗骨料、500‑600份细骨料、50‑80份改性硅灰、5‑8份分散剂、800‑1200份拌合水；本发明将玻璃钢废弃物替代部分砂石填料，实现了废物再利用，节约材料成本并有利于保护环境；通过对废弃玻璃钢纤维进行改性，能有效提高混凝土的机械性能并能降低水分的渗透，减少冻融循环过程中产生的裂缝，提高混凝土的抗冻性能。
