Feldspar waste concrete and preparation method thereof
The invention is applicable to the technical field of concrete, and provides feldspar waste concrete and a preparation method thereof. The feldspar waste concrete is prepared from, by weight, 80-100 parts of feldspar waste, 40-60 parts of cement, 20-40 parts of nanometer aluminum oxide powder, 10-30 parts of coal ash, 40-60 parts of coarse aggregate, 20-40 parts of medium sand, 10-30 parts of argil, 10-12 parts of modifier and 8-10 parts of water, wherein the modifier is prepared from triethoxyvinylsilane and a beta naphthalene sulfonic acid sodium formaldehyde condensate. According to the concrete disclosed by the invention, internal gaps of the concrete can be reduced to a certain extent by adding the nano aluminum oxide powder and the fly ash, and meanwhile, the impact toughness of theconcrete is improved; by adding the modifier, internal gaps of the concrete can be effectively reduced, so the concrete disclosed by the invention has good later strength.
本发明适用混凝土技术领域，本发明提供了一种长石废料混凝土及其制备方法，所述混凝土包括以下重量份的组分：长石废料80‑100份、水泥40‑60份、纳米氧化铝粉20‑40份、粉煤灰10‑30份、粗集料40‑60份、中砂20‑40份、陶土10‑30份、改性剂10‑12份、水8‑10份，所述改性剂包括三乙氧基乙烯基硅烷和β‑萘磺酸钠甲醛缩合物；本发明中的混凝土通过加入纳米氧化铝粉和粉煤灰可在一定程度上减少混凝土的内部空隙，同时提高了混凝土的冲击韧性；通过加入改性剂可有效的减少混凝土的内部空隙，从而使得本发明中的混凝土具有良好的后期强度。
