Concrete for ultrahigh column and pouring method of ultrahigh column
The invention relates to the field of building materials, and particularly discloses concrete for an ultrahigh column and a pouring method of the ultrahigh column. The concrete for the ultrahigh column is prepared from the following raw materials in parts by weight: 460 to 550 parts of cement, 40 to 50 parts of coal ash, 600 to 650 parts of natural sand, 300 to 500 parts of gravel, 12 to 15 parts of a water reducing agent, 6 to 12 parts of hybrid fiber, 0.9 to 2.5 parts of an expanding agent, 240 to 300 parts of water, 40 to 60 parts of a reinforcing agent and 20 to 30 parts of a water-retaining agent. The water-retaining agent is prepared from the following raw materials in parts by weight: 1 to 3 parts of bacterial cellulose, 0.5 to 1 part of rhizoma polygonati polysaccharide zymolyte and 3 to 7 parts of MOFs-polyacrylamide composite microspheres. The concrete for the ultrahigh column can be used for pouring the ultrahigh column, and has the advantages of low early hydration heat and small shrinkage cracking.
本申请涉及建筑材料领域，具体公开了一种超高柱用混凝土及超高柱的浇筑方法。一种超高柱用混凝土，包括以下重量份的原料：460‑550份水泥、40‑50份粉煤灰、600‑650份天然砂、300‑500份碎石、12‑15份减水剂、6‑12份混杂纤维、0.9‑2.5份膨胀剂、240‑300份水、40‑60份增强剂、20‑30份保水剂；所述保水剂包括以下重量份的原料：1‑3份细菌纤维素、0.5‑1份黄精多糖酶解物和3‑7份MOFs‑聚丙烯酰胺复合微球。本申请的超高柱用混凝土可用于浇筑超高柱，其具有早期水化热低，收缩开裂小的优点。
