High-strength concrete as well as preparation method and application thereof
The invention relates to the technical field of concrete, in particular to high-strength concrete as well as a preparation method and application thereof. The concrete is prepared from the following component raw materials in parts by mass: 1 part of cement paste, 1.7 to 2.5 parts of coarse and fine aggregate, 0.0007 to 0.0011 part of L-tartaric acid and 0 to 0.0015 part of high-performance water reducing agent, and the water-binder ratio is 0.25 to 0.45. According to the present invention, the chiral geometrical characteristics and the acidic characteristics of the L-tartaric acid are utilized to regulate the cement hydration process and the types and the number of the hydration products, and the microstructure of the matrix and the interface transition region is improved so as to improve the strength of the concrete;
本发明涉及混凝土技术领域，具体涉及一种高强度混凝土及其制备方法、应用。该混凝土包括以质量份计的以下组份原料：1份的水泥浆、(1.7～2.5)份的粗细集料、(0.0007～0.0011)份的L‑酒石酸和(0～0.0015)份的高性能减水剂，水胶比为0.25～0.45。本发明利用L‑酒石酸的手性几何特征和酸性特质，调控水泥水化进程及水化产物的种类和数量，改善基体和界面过渡区的微观结构，从而提高混凝土的强度。
