The net-zero and sustainability potential of SCC development, production and flowability in concrete structures

Abstract Climate action around the world has shifted to potential of global warming contribution from design and construction infrastructures, especially those in demand for concrete. Concrete production use have been identified as contributing >5% world’s greenhouse gas (GHG) emissions. The main aim this research work is critically study net-zero sustainability potentials that can leverage on development, flowability self-compacting concrete (SCC). Conventional made >50% ordinary cement, which contributes >7% GHG But 1988, a fluidized compacts under its self-weight, known SCC, was formed developed overcome need durability, skill manpower were dwindling Japan at time. This created pathway cement be replaced partially or totally by certain pozzolanic materials function viscosity-modifying admixture, high-water reducing agent microencapsulated phase-change mix. However, findings shown these alter there reduced yield stress moderate viscosity allowable internal friction based Bingham model, achieved same water–cement ratio. Fortunately, implication admixtures replacements cleaner and, such, CO2 emission associated with process.
