Abstract

The objective in this study is to apply the sustainable chemistry and photo-thermal synthesis technology to produce the sustainable eco-superplasticiser for the sustainable high performance SCC concrete especially in hot tropical countries. A photo-thermal synthesized eco-superplasticiser (PSES) was produced by using photo-thermal catalyst in a solar chemical reactor. In this preliminary study, an unique high early strength of SCC concrete has been successfully produced by imposing an unique proportion of the photo-thermal-synthesized ecoSuperplasticiser (PSES), local fly ash, sand and aggregate. The SCC concrete is preliminary tried in the precast concrete product to produce the complicated geometries as Tunnel segment, U-shape beam, and Box girder which have the critical reinforcement and thin section concrete. Surprisingly, this SCC provide the benefits as eliminating steaming energy, increased productivity, and minimize pollution. These unique properties of sustainable SCC concrete can not be achieved by the convention concrete by using ligno, naphthalene and melamine base superplasticiser. The synthesized sustainable eco-superplasticiser is a perfect choice to fully utilized the renewable energy and improve the concrete working environment.
