Aggregated Soft Concrete Prep

Aggregated Soft Concrete Prep

This is a typical aggregated floor. After initial prep by using coarser grit diamond tool, the sizes of aggregates exposed and as you may see the cement surrounding aggregates are less, which indicates the cement was fading out by time. Cement plays like the 'adhesive' holding on every aggregate, the more the cement is gone, the less holding will be, and the more porosity to be seen, the whole floor becomes soft and loose. 

 Grinding aggregated soft concrete floor should using soft or super soft bond diamond tools in order to effective work out the surface and save the longevity of diamond tooling, though it still usually consumed more and faster than prepping the regular hardness of concrete floors.
