A method of preparing and decontaminating a substrate surface to remove contaminants including the steps of applying a first dry or fluid composition having a pH of 4 or less comprising an acidifier and an oxidizer, allowing the first composition to remain on the substrate surface for a predetermined period of time, and rinsing the first composition from the substrate surface with a second composition having a pH of 8 or more comprising an alkaline material liquid mixture formed utilizing activated carbon filtered potable water to achieve a neutral pH condition on the surface, and then applying a nanotubes coating on the surface.

A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.

Surface retarder coating compositions of the invention are based on the use of at least one non-Ordinary Portland Cement (non-OPC) binder and at least one OPC set retarder agent, which are provided in powder form that can be mixed with water at the construction site. The coating is applied onto the surface of a mould or formwork using roller or spray equipment, and concrete can then be cast within 30-60 minutes against the coating. The OPC set-retarding agent operates to retard setting of the concrete so that it can be de-moulded the next day and its surface can be removed using a high pressure water spray to reveal aggregate embedded beneath the removed surface.
