Underwater concrete containing high-titanium heavy slag
The invention belongs to the technical field of cast-in-place concrete, and particularly relates to underwater concrete containing high-titanium heavy slag. Comprising the following components in parts by mass: 250 to 370 parts of cement, 80 to 95 parts of fly ash, 50 to 60 parts of phosphorus slag powder, 970 to 1110 parts of high-titanium heavy slag sand, 800 to 865 parts of high-titanium heavy slag stone, 190 parts of water and 8.51 to 12.97 parts of an additive, and the strength grade of the underwater concrete is C25-C40. A large amount of industrial solid wastes such as the high-titanium heavy slag sand, the high-titanium heavy slag stone, the coal ash and the phosphorus slag powder are utilized, the weight ratio of the solid wastes reaches 80% or above, the solid wastes and the cement are effectively combined by adjusting the dosage of all the components, and the obtained underwater concrete has high cohesive force, dispersion resistance and segregation resistance, and has the advantages of being high in strength, good in water resistance and the like. The characteristics of self-leveling and self-compacting underwater to form high quality and uniformity are realized.
本发明属于灌注混凝土技术领域，具体涉及一种含高钛重矿渣的水下混凝土。包括以下质量份的组分：水泥250～370份，粉煤灰80～95份，磷渣粉50～60份，高钛重矿渣砂970～1110份，高钛重矿渣石800～865份，水190份，外加剂8.51～12.97份；所述水下混凝土的强度等级为C25‑C40。本发明大量地利用工业固体废弃物高钛重矿渣砂、高钛重矿渣石、粉煤灰、磷渣粉，固体废弃物重量占比达到80％以上，通过对各组分的用量调整，有效将固体废弃物与水泥结合起来，得到的水下混凝土不仅具有高黏聚力，抗分散、离析性能，并具有在水下自流平、自密实形成优质、均匀的特点。
