Solid and liquid concrete waste is collected from a construction site and safely off-loaded at a treatment site. Solid waste is separated and sent to a crusher to be made into road bed aggregate. Liquid waste is put in a first tank to settle the solids, then moved to a second tank to settle remaining fine solids, and moved to a third tank coupled to a circulation pump with CO 2 gas injection ...

Step 1: The first grinding session involves the use of the coarsest abrasive pad.This will remove worn-out finishes or coatings at the top of the slab. Step 2: The coarse abrasive pad is replaced by pads with finer grits and then a finer one, gradually until the desired shine and smoothness is acquired.; Step 3: For a dry method, the dust is vacuumed and cleaned off of the surface.

A concrete floor can be scarified using a pneumatic, electrical or internal-combustion driven milling cutter, which creates a rough surface and removes all of the laitance. This is a highly effective and efficient technique, especially for the removal of oily or grimy surfaces from old floors, and of coating films and peeling paint surfaces.

Currently, marble waste is valued by incorporating powders, obtained by drying and grinding sludge resulting from marble blocks cutting operation, or the aggregates, obtained by crushing the solid waste, on self-compacting concrete. These two procedures require a lot of energy. This experimental and theoretical work focuses on the direct incorporation of marble sludge in self-compacting concrete.

We use grinding if your concrete surface is uneven and has several dents. Our grinding tool carefully and steadily removes the damaged surface layer to reveal the undamaged and clean inner layer of concrete. This layer is strong, relatively porous, and tends to accept finishing systems like concrete coatings or polish more easily.
