Materials play an important role in enhancing construction productivity. A good example is the development and adoption of self-compacting concrete in a number of construction projects in Japan and in Europe. Because of the self-compacting behavior, significant reduction in manual labor and increase in construction speed result.
Special versions of ECC are being developed at the ACE-MRL for different types of construction practice. Desirable rheological control of the fresh properties is achieved by tailoring of polymer admixture to influence the cement particle-cement particle and cement particle-fiber interactions. The ACE-MRL has successfully developed technologies for spray processing, self-compacting processing and extrusion processing of ECC materials, along with different functional ECC materials, such as lightweight ECC, high early strength ECC.
