Lightweight aggregate concrete and production process thereof
The invention relates to the field of concrete, and particularly discloses lightweight aggregate concrete and a production process. The lightweight aggregate concrete is prepared from the following components in parts by weight: 400 to 800 parts of lightweight aggregate, 300 to 400 parts of cement, 600 to 800 parts of fine aggregate, 80 to 100 parts of fly ash, 140 to 160 parts of tap water and 6 to 10 parts of water reducing agent. The preparation method comprises the following steps: pouring the cement, the fly ash and the fine aggregate into a stirrer, uniformly stirring, adding the tap water, stirring for 2-5 minutes to form cement mortar, adding the lightweight aggregate, stirring for 5-8 minutes, adding the water reducing agent, and stirring for 10-30 minutes to obtain the lightweight aggregate concrete. The lightweight aggregate concrete disclosed by the invention has the advantage of solving the problem of cracking caused by shrinkage and creep of the lightweight aggregate concrete.
本申请涉及混凝土领域，具体公开了一种轻骨料混凝土及生产工艺。轻骨料混凝土包括按重量份计的轻骨料400‑800份、水泥300‑400份、细骨料600‑800份、粉煤灰80‑100份、自来水140‑160份和减水剂6‑10份；其制备方法为：将水泥、粉煤灰和细骨料倒入搅拌机搅拌均匀，再加入自来水搅拌2‑5min形成水泥砂浆，然后加入轻骨料搅拌5‑8min，同时加入减水剂搅拌10‑30min，得到轻骨料混凝土。本申请的轻骨料混凝土具有解决轻骨料混凝土收缩徐变导致开裂的问题的优点。
