摘要：The development of geopolymer concrete technology was initially inspired by environmental issues from the use of cement as one of the main constituents in concrete that contribute to the major greenhouse gas emissions on earth. The utilization of fly ash is expected to reduce cement in concrete so that the effects of environmental pollution can be minimised. Fly ash is a by-product of coal combustion available abundantly in hundreds of coal-fired power plant spread all over Indonesia which also could become a source of the environmental pollutant. The integration of graded concrete technology along with geopolymer concrete can create high-performance structural elements while still being cost efficient. Currently, research development related to geopolymer concrete and graded concrete is potentially applied to public infrastructures such as bridges that can support the economic activities of local people. The application of porous asphalt and an integrated drainage system make GECOBRIDGE become concepts of a smart, efficient, and environmentally friendly bridge, both in terms of construction, operation, and maintenance. GECOBRIDGE is expected to become a bridge that can conserve water through rain harvesting so that it can be utilized for the cultivation of a hydroponic farm in the upstream area.
