High-stone-powder and stone-chip concrete for pouring sound insulation floor slab and preparation method of high-stone-powder and stone-chip concrete

The invention relates to high-stone-powder and stone-chip concrete for pouring a sound insulation floor slab and a preparation method of the high-stone-powder and stone-chip concrete, which belong to the technical field of building components. The high-stone-powder and stone-chip concrete for pouring a sound insulation floor slab is prepared from the following raw materials in parts by weight: 100-120 parts of a composite cementing material, 150-200 parts of limestone stone chips, 320-480 parts of gravel, 5-10 parts of a nonionic surfactant, 5-10 parts of a polytetrafluoroethylene fiber reinforced material, 1-3 parts of crystalline flake graphite, 5-10 parts of hollow glass beads, 4-10 parts of a water reducing agent and 80-150 parts of water. According to the technical scheme, the obtained concrete has good sound insulation performance and strength and is suitable for pouring of sound insulation floor slabs. 本发明涉及涉及一种用于隔音楼板浇筑的高石粉石屑混凝土及其制备方法，属于建筑构件技术领域。一种用于隔音楼板浇筑的高石粉含量石屑混凝土，包括以下重量份的原料：复合胶凝材料100-120份、石灰岩石屑150-
