“…Low temperatures also result in a reduction in the sulfate attack resistance, which is facilitated by a slight increase in CO 2 at 0-5 • C, leading to an increase in the CO 3 2− content [36,103]. The sulfate attack resistance of the LP-PC system can be effectively enhanced by the incorporation of the remaining SCMs [105]. Following the addition of metakaolin, the concrete samples subjected to sulfate attack, and the overall properties and apparent morphology exhibited significant improvements in comparison to those of PC and LP-PC [106].…”

Limestone is commonly used in cement concrete due to its unique nature and type. It has physical effects (nucleation effect and dilution effect) and chemical effects on the hydration process of cement. This paper reviews the effects of three representative limestone materials on the hydration process, hydration products, and hydration kinetics. In the hydration process, the reaction was delayed by limestone powder with a particle size larger than 20 μm and calcium carbonate whiskers due to their dilutive effect. On the other hand, limestone powder with a particle size smaller than 20 m and calcium carbonate nanoparticles facilitated the reaction through nucleation and chemical effects. Limestone has a similar effect on hydration products, promoting the production of C-S-H through nucleation. The mechanism of action for this nucleation effect depends on the differences in crystalline form and particle size of the three types of micro- and nano-calcium. Chemical effects impact the amount of AFt produced, with the generation of new products being the main reaction influenced by the limestone admixture.
