Abrupt temperature change (freeze-thaw cycles) is one of the most damaging actions
affecting concrete, inasmuch as it induces microcracking. The formation of this crack reduces …

Repeated freezing and thawing (FT) cycles are the major reason for the frost damage and
premature failure in concrete structures. Frost damage can be evaluated by its effects on …

One of the most damaging actions affecting concrete is the abrupt temperature change
(freeze‐thaw cycles). The types of deterioration of concrete structures by cyclic freeze‐thaw …

The effect of air-entraining admixture (AEA) on the fresh and rheological behavior of mortars
designed to be used in 3D printers was investigated. Blast furnace slag, calcined kaolin clay …

The paper examines the suitability of three different surfactants as air-entraining admixtures
(AEAs) for air lime mortars. The substances tested were based on sodium dodecyl sulfate …

Durability is a key property in concrete structures exposed to freeze–thaw cycles, particularly
where the concrete mix includes recycled materials. This study explores 25% or 50 …

The effects of air-entraining admixture (AEA), curing process, and core direction were
studied as parameters in terms of their effect on the physicomechanical properties of 3D …

The expected lifespan of cement-based materials, particularly concrete, is at least 50 years.
Changes in the pore structure of the material need to be considered due to external …

This article presents freeze-thaw (F/T) resistance of concrete containing recycled concrete
aggregate (RCA). RCA percentages of 15%, 30%, 45%, and 60% were replaced by natural …

Most of the standards that evaluate the resistance of concrete against freeze-thaw cycles
(FTC) are based on the loss of weight due to scaling. Such procedures are useful but do not …
