Concrete

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...

Nanotechnology in concrete – A review

The frost resistance of concrete comprising nano-Al 2 O 3 is better than that comprising the same amount of nano-SiO 2. The compressive strength of normal concrete containing nano-SiO 2 is higher than that of the same amount of nano-Al 2 O 3. The frost resistance of the concrete mixtures can be improved significantly by adding either nano-Al 2 ...

Concrete Floor Hardeners and Densifiers

The next steps involve fine grinding of the concrete surface using diamond abrasives embedded in a plastic or resin matrix. Crews use ever-finer grits of polishing disks (a process called lapping) until the floor has the desired sheen. For an extremely high-gloss finish, a final grit of 1500 or finer may be used.
