High-titanium slag sand reactive powder concrete and preparation method thereof
The invention provides high-titanium slag sand active powder concrete and a preparation method thereof. The preparation method comprises the steps: drying high-titanium slag, crushing, and grading toobtain graded high-titanium slag sand; uniformly mixing cement, fly ash, silica fume and steel fibers, then adding water and a water reducing agent, and uniformly mixing to obtain slurry; and mixing the graded high-titanium slag sand with the slurry, molding, and curing to obtain the active powder concrete, wherein the reactive powder concrete is prepared from the following components in parts bymass: 55 to 65 parts of high-titanium slag sand, 15 to 24 parts of cement, 5 to 8 parts of fly ash, 2.5 to 4 parts of silica fume, 2 to 5.5 parts of steel fiber, 4.5 to 8.5 parts of water and 0.5 to 1.0 part of a water reducing agent. The product prepared through the method is high in compressive strength and breaking strength, can be used for preparing underground railway channels and sleepers, can also be applied to sponge city construction, underground pipelines, prefabricated assembly pipe galleries and other engineering structures, and is wide in application range.
本发明提供了一种高钛矿渣砂活性粉末混凝土及其制备方法，所述制备方法包括：对高钛矿渣干燥，破碎，级配处理，得到级配处理后的高钛矿渣砂；将水泥、粉煤灰、硅灰与钢纤维混匀，然后加入水和减水剂，混匀后得到浆体；将级配处理后的高钛矿渣砂与浆体混合，成型，养护，得到活性粉末混凝土。所述活性粉末混凝土按质量份计，高钛矿渣砂55份～65份、水泥15份～24份、粉煤灰5份～8份、硅灰2.5份～4份、钢纤维2份～5.5份、水4.5份～8.5份、减水剂0.5份～1.0份。本发明的方法制备得到的产品抗压强度和抗折强度高，可用于制备地下铁路通道、轨枕，也可应用于海绵城市建设、地下管线及预制装配管廊等工程结构，应用广泛。
