This paper presents an extensive review of the properties of fresh concrete, incorporating elements such as workability, heat of hydration, setting time, bleeding, and reactivity, facilitated through the integration of mineral admixtures including fly ash (FA), silica fume (SF), ground granulated blast furnace slag (GGBS), metakaolin (MK), and rice husk ash (RHA). An investigation has been carried out comparing traditional concrete with high-strength concrete, where mineral admixtures have been used to partially substitute cement. Studies indicate that mineral admixtures can be sorted into two unique classifications: chemically active mineral admixtures and micro filler mineral admixtures. Minerals that are chemically active tend to reduce the workability and setting duration of concrete, while also boosting the heat generated during hydration and its reactivity. Alternatively, incorporating micro filler mineral admixtures boosts the workability and setting period of concrete, albeit with the drawback of diminished heat of hydration and reactivity. Typically, a reduced particle size and an increased specific surface area of mineral admixtures facilitate the creation of highly dense and impermeable concrete; however, they often lead to a decline in workability and require a greater water demand, a challenge that can be addressed through the incorporation of a proficient superplasticizer.
