Abstract
Self-compacting concrete (SCC) production is growing rapidly due to its several advantages in terms of enhanced properties and applications. However, there are associated sustainability issues with the SCC materials. With the demand for SCC expected to continually increase, an ideal solution is therefore required to sustain the technology, such as derivation of alternative materials. Thus, this study explores innovative application of industrial wastes in self-compacting concrete production, with the aim of finding the most appropriate technique in SCC material use. Also, the potential limitations in using some of the waste materials as sustainable alternatives were highlighted. This study found that several materials emanating from industrial rejects have been mostly investigated as a potential material for making SCC, which showed that the incorporation of waste materials into SCC could be a viable approach. However, in order to achieve optimal performance of SCC, an adequate material composition is necessary. It is clear from this study that factors such as embodied carbon, energy and cost of SCC production can notably be reduced with the incorporation of waste materials. The study also identified areas for further investigations that can help in the improvement of SCC for construction applications.
Highlights
Advances in concrete material research, in recent years, have opened pathway for the use of alternative materials as sustainable alternatives for the conventional ones
When waste materials are incorporated into self-compacting concrete (SCC) as a replacement for either binder or/and aggregate, the suitability of such materials can only be ascertained if the SCC exhibits similar or better fresh and hardened properties compared to the conventional mixture
Despite higher penetration of chloride ions into SCC containing Coal bottom ash (CBA) compared to the control, the charges passed below 1000 coulombs shows that the SCC is durable to an extent
Summary
Advances in concrete material research, in recent years, have opened pathway for the use of alternative materials as sustainable alternatives for the conventional ones. When waste materials are incorporated into SCC as a replacement for either binder or/and aggregate, the suitability of such materials can only be ascertained if the SCC exhibits similar or better fresh and hardened properties compared to the conventional mixture. Finding ways to incorporate waste materials into concrete will create ways to manage these wastes effectively, but it will create an avenue to produce sustainable concrete It will preserve the sources of raw materials and reduce the carbon footprint of SCC. Most of the studies have reported a decrease in mechanical properties of concrete, which becomes more significant as there was an increase in the in the amount of waste materials incorporated. This review is carried out to extensively explore several experimental studies in the open literature in which waste materials have been incorporated into concrete either as replacement of binder or/and aggregates. The study will guide concrete’s stakeholders on possible ways to incorporate different waste materials into SCC and other types of cementitious composites
