High-strength concrete gravel plate and preparation method thereof
The invention discloses a high-strength concrete gravel plate and a preparation method thereof, and relates to the technical field of building materials. According to the high-strength concrete gravel plate and the preparation method thereof, the grain size of high-strength concrete gravel aggregate is 40-120mm, and the aggregate is flatly laid in a mold after being bisected by a cutting machine; the high-strength concrete filler is prepared from the following materials in parts by mass: 320 to 400 parts of cement, 130 to 200 parts of water, 60 to 80 parts of fly ash, 25 to 35 parts of silica fume, 200 to 250 parts of iron ore sand, 200 to 250 parts of sand and 10 to 20 parts of a water reducing agent. The characteristic of high strength of the large-particle-size sand gravel aggregate is fully utilized, and the high-strength concrete filler is matched, so that the 28d compressive strength of the prefabricated product is 70MPa or above. The concrete product is excellent in performance and high in compressive strength, waste materials of 40 mm or above in concrete raw materials are fully utilized, waste of the raw materials is avoided, the manufacturing cost is low, and economic benefits are remarkable.
本发明公开了一种高强混凝土砾石板及其制备方法，涉及建筑材料技术领域。该高强混凝土砾石板及其制备方法，高强混凝土砾石骨料采用粒径为40‑120mm，所述骨料经切割机对切后平铺于模具中；所述高强混凝土填充料包括以下质量份的材料：水泥320‑400份，水130‑200份，粉煤灰60‑80份，硅灰25‑35份，铁矿砂200‑250份，砂200‑250份，减水剂10‑20份。本发明充分利用大粒径砂砾石骨料本身具有高强度的特点，搭配高强度混凝土填充物，使得预制品28d的抗压强度在70MPa以上。该混凝土制品性能优良，抗压强度高，充分利用混凝土原材中40mm以上的“废料”，避免了原材的浪费，制成成本低廉，经济效益显著。
