additive materials in concrete

Additive Manufacturing with Cement-based Materials | NIST

Additive Manufacturing (AM) with concrete, also known as 3-D Concrete (3DCP), is an emerging technology in the construction industry. This approach to concrete construction has the potential to change the way cementitious materials are used to create infrastructure components. Automating the placement of concrete materials may improve construction efficiency by eliminating …

The use of pozzolans in concrete - Concrete Countertop ...

Pozzolans as Cement Replacements. Typically pozzolans are used as cement replacements rather than cement additions. Adding pozzolans to an existing concrete mix without removing an equivalent amount of cement increases the paste content and decreases the water/cement ratio. In other words, adding more pozzolans to a mix changes the mix proportions.
