“…Dynamic testing Standard (high-pH) grout mixture (HP) [7] Low-pH grout mixture (LP) [7] LP2-10% LP2-20% LP2-30% LP2-40% [7] is advantageous not only for its non-destructive manner but also for obtaining intrinsic material properties because dynamic properties are from the small strain range far below the elastic limit and are directly related to the internal structure [16]. In this study, the dynamic properties of cement grout material are determined by the free-free resonant column (FFRC) method (KS F2437) [17], which is similar to the method in ASTM C215 [18].…”

“…Additionally, infrastructure concrete designed for colder climates is entrained with discrete spherical pores to improve its freeze-thaw durability. Concrete mechanical properties change with the amount and distribution of permeable and discrete pores and the amount of moisture within the permeable pore structure [11,12].…”

A B S T R A C T R I~ S U M I~The findings of an experimental study are described, documenting and quantifying the influence of concrete porosity on its mechanical properties in saturated and dry states. Concrete porosity consists of capillary and entrained air, and described respectively as active and nonactive, depending on its influence on mechanical properties with changing moisture state. It was found that the active (capillary) porosity influence on mechanical properties is more pronounced with decreasing moisture. The influence of non-active (entrained-air) porosity on concrete mechanical properties is invariant of moisture state. Les principaux r~sultats d'une ~tude visant h quantifier l'influence de la porosit( sur les propri(t~s m~caniques du b~ton (~ l'~tat sec et saturn) sont pr~sent~s. La porosit~ du b(ton consiste en des pores capillaires et des vides el'air entrafn~ qui sont respectivement d(crits comme actifs et non-actifs selon leur influence sur les proprie~t(s mdcaniques du b(ton test( ~ cliff, rents degr~s de saturation. Les r~sultats des essais d~montrent que l'influence des pores capillaires (actifs) est inversement proportionnelle au degr~ de saturation du b~ton. Les effets des vides d'air entrafnk (non-actifs) apparaissent comme ~tant peu sensibles au degr~ de saturation du mat&iau.

“…It is obvious that the modulus of elasticity increases in the following order for different mineral admixtures: SF, UFG and LS. This trend could be explained by the different rates of hydration of the mineral admixtures, the availability of water for hydration and the presence of water filled pores in the different mixes [22]. The adverse effect of the LS admixture on the concrete modulus of elasticity was pronounced to be the lowest when compared with the other mineral admixtures; however, this value was higher than the control mix concrete value.…”

“…Swamy [22] attributed this change in the modulus of elasticity to the removal of moisture from capillary channels, as a result of the effect of the hydration process of concrete. In this research it is believed that the change can be attributed to the different speeds of the hydration process.…”

-This research aims to investigate the effect of introducing different mineral admixtures on the mechanical properties of concrete. The research is focused on optimizing the properties of fresh and hardened concrete, looking in particular at how factors such as slump, unit weight, air entrancement, compressive strength, tensile strength, flexural strength and modulus of elasticity are affected by different mineral admixtures in a concrete mix. Different mineral admixtures are used, namely silica fume, limestone and ultra-fine gypsum, and for the tests each mineral admixture replaced 25 % of the cement. The paper also compares the performance of the fresh and hardened properties of concrete.
