The Impact of Sustainable Materials on the Fresh and Hardened Characteristics of Self-compacting Concrete: A Review
摘要
The production of self-compacting concrete with sustainable material is more complex than incorporating it into ordinary concrete, as the major objective of self-compacted concrete is to get superior fluidity instead of strength and durability. The current review presents 48 research studies, including 29 research talking about supplementary cementitious materials “Silica fume, Fly ash, Ground granulated-blast furnace slag, Meta-kaolin, and Rice husk ash” and 19 research talking about industrial waste materials “ Glass waste, Plastic waste, and Rubber waste” on fresh characteristics “Slump, V-funnel, J-ring, L-box”, as well as hardened characteristics “compressive, flexural, splitting strength and modulus of elasticity”. The findings indicate that sustainable materials such as SCMs and waste materials positively affect fresh and hardened SCC. Furthermore, after reviewing, there is a gap. Additional research is required to comprehend the long-term durability of SCMs, optimize multi-blended combinations, and investigate the interaction between PET and other SCMs to enhance dispersion and bonding properties.
