Preparation method of five-super inorganic cementing material and product thereof
The invention relates to the field of concrete preparation, in particular to a five-super inorganic cementing material and a preparation method of a product of the five-super inorganic cementing material. 0-10 parts of fly ash; 15 to 18 parts of 1 mm quartz sand; 20 to 25 parts of quartz sand of 40 to 70 meshes; 0.4 to 0.6 part of a dispersant; 0.1 to 0.2 part of early strength agent; 0-5 parts of quick lime; 0 to 0.05 part of a graphene emulsion; 0 to 0.5 part of alum; 0.1-0.5 part of a water reducing agent; 0-1 part of glutinous rice water; according to the present invention, the ultra-high strength and the ultra-high toughness can be obtained by adding the dispersant without adding the fiber, such that the concrete has the ultra-high flow state and can be filled into the gaps of the lining pipe, and the viscosity strength of the concrete can achieve more than 1.5 MP by adding the sulphoaluminate cement and the fly ash so as to completely meet the requirements of the protection sleeve; by adding the early strength agent, the 2h strength of the concrete can reach 20MPa, and then the concrete can be demolded within 2h, so that the concrete is suitable for streamlined production, the working strength is reduced, the working efficiency is improved, the occupied working space is reduced, and the flow ratio is increased.
本申请涉及混凝土制备领域，尤其涉及一种五超无机胶凝材料及其制品的制备方法，包括以下质量份的原料：硫铝酸盐水泥40～55份；粉煤灰0～10份；1mm石英砂15～18份；40～70目石英砂20～25份；分散剂0.4～0.6份；早强剂0.1～0.2份；生石灰0～5份；石墨烯乳液0～0.05份；明矾0～0.5份；减水剂0.1～0.5份糯米水0～1份；添加分散剂而无需添加纤维即可获得超高强度和超强韧性，使得混凝土有超高流态，可充填到内衬管的间隙中，添加硫铝酸盐水泥和粉煤灰，混凝土的粘性强度可达到1.5MP以上，完全符合保护套的要求；通过添加早强剂，该混凝土的2h强度可达到20MPa，进而在2h即可脱模，适合流水化生产，减轻工作强度，提高工作效率，减小工作空间的占用，增加流转比数。
