Abstract
High-performance concrete (HPC) that draws on supplementary cementitious materials (SCMs) and recycled coarse aggregate (RCA) is attracting growing research interest as the construction sector seeks to reduce both its carbon footprint and its dependence on virgin resources. This paper reviews recent experimental investigations into the individual and combined use of rice husk ash (RHA), silica fume (SF), fly ash (FA), ground granulated blast furnace slag (GGBFS), metakaolin (MK), and alccofine as partial cement replacements, together with RCA as a natural aggregate substitute. Optimal replacement levels of RHA (10–20%), SF (10–20%), GGBFS (30–40%), and MK (7.5–12.5%) raise compressive strength by 5–45% while densifying the pore structure and extending service life. RCA can replace up to 50–60% of natural aggregate without unacceptable strength loss when SCMs are incorporated. RHA also acts as an internal curing agent in ultra-high performance concrete, delaying self-desiccation and markedly reducing autogenous shrinkage. Critical research gaps are identified and recommendations for future investigations toward environmentally sustainable HPC are provided.
