Oligomer prepared from superfine blast furnace slag powder and preparation method thereof
The intention relates to the technical field of road engineering, in particular to an oligomer prepared from superfine blast furnace slag powder and used for road surface void treatment grouting materials and a preparation method of the oligomer. The oligomer comprises a component A, a component B and water, and the weight ratio of the component A to the component B is 1: 0.45; wherein the component A is composite powder which is obtained by grinding blast furnace slag and fly ash in a weight ratio of 70%: 30% through a ball mill with the size of theta 3.2 * 13m and has the D5010mu m and the specific surface area of more than or equal to 700m < 2 >/g; the component B is prepared from the following raw materials in parts by weight: 6-6.5 parts of an alkaline exciting agent, 1.5-2 parts of an additive I, 0.03-0.05 part of an additive II, 0-12 parts of an additive III and 79.45 to 92.47 parts of water. After reaction, the oligomer grouting material is compact in structure and low in pressure bleeding rate, the road bearing capacity is improved, the capacity of resisting cracks generated by bending and tensile deformation is improved, and the water scouring resistance is improved.
