Blasting opens the pores and roughens the surface, providing an interface for the patching material. Impact tools used to remove unsound concrete cause extensive microcracking. Patching a surface weakened by microcracking defeats the purpose of the repair. Abrasive blasting is the preferred method to remove the microcracked surfaces.

Apr 01, 2018 The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at
The steel slag is much harder, making it harder to crush because of its higher compressive strength. According to Coverdale, if youre crushing steel slag, you want to use a compression style crusher, and when youre crushing blast furnace slag, you can get away with impact style crushers from time to time.
