Like the mortar used for brick and concrete block construction, which is simply made with mortar cement and sand, mortar concrete has no coarse aggregate in it, so a ground finish will have a finegrained appearance. Mortar concrete is commonly used in concrete countertop mixes, since the surface finish is so important.
Another example is polymer concrete which uses a catalyst to bind aggregates together. It''s pressed instead of poured and used in applications where a higher corrosion resistance is needed ( sanitary sewer manholes). Other types of concrete include highperformance concrete, pervious concrete.
The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is .
