“…occurs earlier for all mortars containing CS in comparison with that of NS indicating an acceleration of the cement hydration in the presence of finely ground limestone. This conformed to the observed results by Thongsanitgarn et al [38] in which the maximum heat of hydration was observed around 6.5 h for limestone cement and 10 h for ordinary cement. Accordingly, the cumulative heat expressed per gram of clinker is higher for the mortar containing CS especially with limestone cement.…”

This work aims to evaluate the characteristics of crushed sand (CS), resulting from limestone quarries, when it replaces natural sand (NS) in mortar, and to identify its performances with three types of cement and three W/C ratio. It is concluded that CS has a great effect on mortar properties; it accelerates the hydration of cement grains leading to a shorter setting time, increases the flexural and compressive strengths, generates more hydration heat, and improves the mortar durability. The properties of CS mortar can be predicted as simple relationships of those of NS with an acceptable correlation coefficient.

“…Fly ash is well recognized to provide a slow rate of heat generation and thus is very effective in reducing the heat of hydration [13,14,16,22]. The heat of hydration in mixtures including GCC may increase or decrease [23,24], depending on the particle size of GCC. The rate of CH consumption in MK binary mixtures is reported to be higher than that of SF binary mixtures [22], followed by a relatively slower consumption rate in slag and fly ash mixtures [13,14,16,22].…”

Novelties in Material Development for Massive Concrete Structures: Reduction in Heat of Hydration Observed in Ternary Replacement Mixtures

As the size of modern infrastructure increases, novelties related to mass concrete mixtures including supplementary cementitious materials (SCMs) become critical. The effects of binary and ternary cement replacement mixtures including metakaolin, silica fume, ground calcium carbonate, granulated blast furnace slag, and fly ash on the rate and amount of heat generated in concrete mixtures are investigated. Twenty three binary and ternary mixtures with a water-to-cementitious binder ratio of 0.43 are evaluated. Between 15% and 45% cement replacement by weight is considered. Results indicate that binary mixtures containing metakaolin or silica fume offer no advantage in reducing the amount of heat but increase compressive strength by 20%. On contrary, ternary mixtures, including two pozzolanic materials, provide 15% reduction in the amount of heat evolution without compromising strength. This reduction is observed regardless of alumina (Al) or silica (Si) content in pozzolanic materials when 45% cement is replaced with a combination of slag and metakaolin, or slag and silica fume. Furthermore, the effect of increased calcium (Ca) content is investigated. It is concluded that ternary mixtures with decreased Ca/(Al+Si) ratio reduce internal temperature in mass concrete structures and are less likely to be exposed to the threshold temperature for delayed ettringite formation.

“…Where limestone is used as an addition to cement, heat of hydration is generally increased (Praay et al 1999;Tsivilis et al 2002;Vuk et al 2001;Thongsanitgarn et al 2014). However, it is noted that substitution of clinker with limestone fillers reduced the release of heat, height of the main peak or the total heat released (Marzouki et al 2013;Irassar et al 2011).…”

“…The particle size of limestone powder was found to have an influence on the heat of hydration both on the rate of heat and the total amount of heat release. Thongsanitgarn et al (2014) reported that the early-age hydration rate was accelerated by the finer particle size, while no significant effect was observed when particle size was 20μm or larger.…”
