Low-shrinkage high-strength concrete
The invention provides low-shrinkage and high-strength concrete, and belongs to the technical field of concrete preparation. The low-shrinkage high-strength concrete is prepared from the following components in parts by weight: 150 to 180 parts of cement, 80 to 100 parts of a mineral admixture, 800 to 850 parts of sand, 1000 to 1100 parts of stone, 150 to 200 parts of water, 3 to 10 parts of a water reducing agent and 1 to 3 parts of a glue reducing agent. Silicon powder is added into the concrete to improve the strength of the concrete, lignin is modified and matched with tannic acid to be used in the glue reducing agent of the concrete to improve the workability of the concrete, and the low-shrinkage high-strength concrete has the characteristics of high strength and good workability.
本发明提供了一种低收缩高强度混凝土，属于混凝土制备技术领域，本发明的低收缩高强度混凝土，包括按重量份计的150‑180份水泥、80‑100份矿物掺和料、800‑850份砂、1000‑1100份石子、150‑200份水、3‑10份减水剂、1‑3份减胶剂。通过在混凝土中加入硅粉增加混凝土的强度，并对木质素进行改性配合单宁酸使用在混凝土的减胶剂中来增加混凝土的和易性，本发明的低收缩高强度混凝土具有强度高和易性好的特点。
