Aggregates are no longer just rock, but may be natural stone, man-made materials, or recycled concrete materials. These are just a few ways concrete pavements have changed over the years. The descriptions below show other technologies that make concrete pavements so versatile and useful for just above every construction strategy and application.

Recycled concrete aggregate could be produced from (a) recycled precast elements and cubes after testing, and (b) demolished concrete buildings. Whereas in the former case, the aggregate could be relatively clean, with only the cement paste adhering to it, in the latter case the aggregate could be contaminated with salts, bricks and tiles, sand and dust, timber, plastics, cardboard and paper ...

The cost of an aggregate concrete driveway can vary wildly depending on a number of different factors, how the driveway is poured and what materials are used. Opting to hire a professional will be an extra expense, but it is always advised due to the labor-intensive nature of the job as well as the speed at which aggregate needs to be exposed in order to look attractive. The size of the ...

Used in many applications, air-entrained concrete uses a chemical admixture (or sometimes, air-entraining cement) to produce a system of small voids during the mixing process. These voids are stabilized by the air-entraining admixture and remain in the hardened concrete paste. The primary use of air-entraining concrete is for freeze-thaw resistance. The air voids provide pressure relief sites ...

Produced during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete. It can also be used to absorb contaminants like phosphate, magnesium, iron, calcium, silica and aluminium in the wastewater treatment process, but loses its effectiveness over time.
