Machine-made sand concrete as well as preparation method and application thereof
The invention discloses machine-made sand concrete as well as a preparation method and application thereof. The machine-made sand concrete is prepared from the following components in parts by weight: 350 to 370 parts of cement, 50 to 100 parts of fly ash, 100 to 150 parts of mineral powder, 40 to 60 parts of microbeads, 700 to 820 parts of sand, 1000 to 1200 parts of gravel, 12 to 16 parts of additive and 140 to 150 parts of water. The C80 concrete with low yield stress is prepared by blending the raw materials, indexes such as yield stress, plastic viscosity and the like are taken as the basis of pumping performance, and the expansion degree and the collapse time are taken as auxiliary indexes, so that the pumping pressure is reduced, and the pumping efficiency is improved.
本发明公开了一种机制砂混凝土及其制备方法与应用，包括以下重量份数的组分：水泥350‑370份、粉煤灰50‑100份、矿粉100‑150份、微珠40‑60份、砂700‑820份、碎石1000‑1200份、外加剂12‑16份和水140‑150份。本发明通过原料间的调配制得一种低屈服应力的C80混凝土，以屈服应力、塑性粘度等指标作为泵送性能的基础，以扩展度、倒坍时间作为辅助指标，用以降低泵送压力，提高泵送效率。
