High-strength concrete taking carbon chromium slag as main aggregate, processing device and preparation process of high-strength concrete
The invention discloses high-strength concrete with carbon chromium slag as main aggregate, a processing device and a preparation process of the high-strength concrete. The high-strength concrete is prepared from high-strength aggregate, a magnesium chloride solution, a defoaming agent, light calcined magnesia, fly ash, deionized water, a composite modifier, polypropylene fiber powder, zinc maleate, acrylamide and dibenzoyl peroxide. According to the invention, the composite modified carbon chromium slag is used as a main aggregate, the nickel iron slag is used as an auxiliary aggregate, the solid waste is used for replacing the traditional gravel aggregate, and the magnesium cementing material is used for replacing the cement, so that the strength of the concrete is improved, the surface hardness is high, the wear resistance is strong, the concrete is not easy to crack and wear, and the use requirements of high-strength scenes are met; the carbon chromium slag is subjected to reduction, recycling and high-value comprehensive utilization, the added value is high, the utilization amount is large, the problem of accumulation of the carbon chromium slag is solved while gravel aggregate is replaced, and the carbon chromium slag is high in tensile strength, high in toughness, resistant to cracking and seepage, long in service life and reliable in work.
本发明公开了以炭铬渣为主要骨料的高强混凝土、加工装置及其制备工艺，配方包括：高强度骨料、氯化镁溶液、消泡剂、轻烧氧化镁、粉煤灰、去离子水、复合改性剂、聚丙烯纤维粉、马来酸锌、丙烯酰胺和过氧化二苯甲酰；该发明以复合改性的炭铬渣为主要骨料、镍铁渣为辅助骨料，用固体废弃物代替了传统的砂石骨料，并用镁质胶凝材料代替了水泥，从而提高了混凝土的强度，表面硬度高、耐磨性强，不易破裂磨损，满足了高强度场景的使用需求，且对炭铬渣进行了减量化、资源化和高价值的综合利用，附加值高，利用量大，代替砂石骨料的同时也解决了炭铬渣的堆积问题，且高抗拉强度、高韧性，抗裂防渗，使用寿命长，工作可靠。
