Machine-made sand concrete based on limestone chips as well as preparation method and application of machine-made sand concrete
The invention discloses machine-made sand concrete based on limestone chips as well as a preparation method and application thereof, and the machine-made sand concrete comprises the following components in parts by mass: 160-175 parts of water, 200 parts of cement, 80 parts of mineral powder, 80 parts of fly ash, 435-696 parts of machine-made sand, 174-435 parts of limestone chips, 950 parts of gravel, 5.8 parts of a water reducing agent and limestone chips. The interface bonding performance of the cement and the aggregate is enhanced, and the strength of the concrete is improved; the limestone chips are low in activity, and the early-stage shrinkage cracking phenomenon of the concrete can be reduced by matching the limestone chips with the machine-made sand.
本发明公开一种基于石灰岩石屑的机制砂混凝土及其制备方法与应用，包括质量份数如下的组分：160‑175份水、200份水泥、80份矿粉、80份粉煤灰、435‑696份机制砂、174‑435份石灰岩石屑、950份碎石、5.8份减水剂，石灰岩石屑，其组分中含有大量的碳酸钙，增强水泥与集料的界面粘结性能，提升混凝土的强度；石灰岩石屑的活性低，与机制砂进行配比可减少混凝土的早期收缩开裂现象。
