Concrete preparation method using compound doping machine-made sand and dredged sand as fine aggregate
The invention discloses a concrete preparation method taking compound doping machine-made sand and dredged sand as fine aggregate, and relates to a mix proportion design and manufacturing method of concrete. The invention relates to a concrete material taking compound doped machine-made sand and dredged sand as fine aggregates. The concrete material is prepared from the fine aggregates, coarse aggregates, fly ash, sodium hydroxide, sodium silicate and a water reducing agent, wherein the fine aggregate is co-doped machine-made sand and dredged sand, and the coarse aggregate is artificial soft stone formed by crushing cobblestones. The fly ash is solid waste discharged from a coal-fired power plant. The preparation process is greatly simplified by providing the mix proportion, the raw materials are saved, the early strength advantage is obvious, the compressive strength and the anti-permeability performance are excellent, and the use and popularization value is good.
本发明一种以复掺机制砂与疏浚砂为细骨料的混凝土配置方法涉及的是一种混凝土的配合比设计及制作方法。一种以复掺机制砂与疏浚砂为细骨料的混凝土材料，由细骨料、粗骨料、粉煤灰、氢氧化钠、硅酸钠和减水剂组成；其中细骨料为复掺机制砂与疏浚砂，粗骨料为鹅卵石破碎后形成的人工软石。所述的粉煤灰为燃煤电厂排出的固体废物。本发明提出的配合比的提出极大简化了制备过程，节约了原料，早期强度优势明显，抗压强度抗渗性能优异，具有良好的使用和推广价值。
