Abstract

The invention relates to superfine slag powder. The superfine slag powder is prepared from the following components in parts by mass: 80-100 parts of slag, 10-30 parts of slag, 10-15 parts of waste rock, 1-3 parts of surfactant and 2-3 parts of nanoscale graphene. The invention further provides a grinding treatment method of the superfine slag powder. According to the superfine slag powder, the waste rock and the nanoscale graphene are added, so that the strength and quality of the superfine slag powder can be effectively improved; and with the manufacturing method adopted, the production efficiency of products can be effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a slag micropowder and a grinding treatment method thereof. Background technique [0002] Slag micropowder is a powder obtained by drying and grinding granulated blast furnace slag to a certain fineness and meeting the requirements of the activity index. Through mechanical energy activation and chemical energy activation, its potential activity is fully exerted, and it becomes a highly active auxiliary gelling material. Slag micropowder can improve the performance of concrete. On the one hand, the activity of slag is stimulated under alkaline environmental conditions, and the SiO in slag 2 、Al 2 o 3 and cement hydration product Ca(OH) 2 The formation of hydration products such as calcium silicate hydrate further accelerates the process of cement hydration reaction, improves the uniformity of the distribution of cement hydration products, and makes the cement stone s...
