Lightweight ceramsite concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses light ceramsite concrete and a preparation method thereof. The lightweight ceramsite concrete is prepared from the following components in parts by weight: 283 to 355 parts of cement, 440 to 508 parts of sand, 189 to 218 parts of ceramsite, 170 to 180 parts of water, 48 to 60 parts of slag powder, 37 to 49 parts of fly ash and 7.35 to 12.27 parts of an additive, the ceramsite is prepared by the following method: S1, uniformly mixing red clay, waste incineration fly ash and coal, and adding water to prepare green pellets; and S2, drying the green pellets at 100-105 DEG C for 3-4 hours, preheating at 400-450 DEG C for 30-40 minutes, heating to 1160-1180 DEG C, and calcining for 10-12 minutes to prepare the ceramsite. The lightweight ceramsite concrete disclosed by the invention has the advantages of high compressive strength, good heat resistance, difficulty in cracking at high temperature and good adhesive force with reinforcing steel bars.
本申请涉及建筑材料技术领域，具体公开了一种轻质陶粒混凝土及其制备方法。轻质陶粒混凝土包括以下重量份的组分：283‑355份水泥、440‑508份砂子、189‑218份陶粒、170‑180份水、48‑60份矿渣粉、37‑49份粉煤灰、7.35‑12.27份外加剂；陶粒由以下方法制成：S1、将红黏土、垃圾焚烧飞灰和煤炭混合均匀后，加入水，制成生球；S2、将生球在100‑105℃下干燥3‑4h后，在400‑450℃下预热30‑40min，升温至1160‑1180℃煅烧10‑12min，制成陶粒本申请的轻质陶粒混凝土具有抗压强度高，耐热性好，高温下不易开裂且与钢筋的粘着力好的优点。
