In the literature, there are some conflicting results regarding the influence of metakaolin (MK) addition on autogenous shrinkage behavior of cementitious materials. In this study, with the aim of identifying how the use of MK changes the properties

Air entraining admixtures (AEA) are generally used for increasing the workability and resistance to freezing and thawing in concrete. These admixtures generate air bubbles with diameters ranging from 10 μm to 1 mm, providing spaces for the expansion

Thermal conductivity of the materials used in buildings is one of the major factors affecting the heat transfer. Higher thermal conductivity of building walls results in higher heat losses, and in order to maintain the same temperature inside a build

Repeated freezing and thawing (F-T) cycles are the major reason for the frost damage and premature failure in concrete structures. Frost damage can be evaluated by its effects on formation of internal cracks and scaling at the surface of concrete. Bo

Metakaolin, a dehydroxylated product of the mineral kaolinite, is one of the most valuable admixtures for high-performance concrete applications, including constructing reinforced concrete bridges and impact- and fire-resistant structures. Concretes

Partial replacement of cement by metakaolin (MK) increases the strength of concrete, but since the properties of MK are important parameters it is not entirely clear whether MK is more effective than silica fume (SF) in enhancing the properties of co

Fracture process zone has a strong effect on fracture energy particularly for concretes with coarse aggregates. In order to demonstrate this effect, four groups of concrete mixtures with various aggregate volume fractions were designed. Three point b

The factors that influence the reliability of the correlations between the properties of concretes with water-cement ratios between 0.26 and 0.42, tested at the ages of 7, 14, 28 and 365 days, were investigated. For this purpose, from the strength of
