Jul 05, 2014· Most mechanical processes for removing sealers and coatings involve grinding, scraping or blasting, all of which impact the concrete surface and tend to profile or scratch the surface. This is why chemical strippers, which do not impact the concrete surface, are the most common method for removing sealers and coatings from stamped concrete surfaces.

The efficiency, which the molten blast furnace slag is rapidly chilled, as well as the chemical composition of the slag source, largely determines its cementitious properties for use in concrete. After the granulated blast furnace slag is formed, it must be dewatered, dried and ground, using processes similar to those used with Portland cement ...

Comminution and especially cement grinding still account for the majority of the electrical energy demand of cement production. As Fig. 12 shows, between 60% and depending on cement properties up to 70% of the roughly 100–110 kWh of electrical energy per ton of cement are used for comminution processes, . It has to be noted that these values strongly depend on production fineness and therefore vary .
