Abstract: This paper reports the results of experimental study on the effects of mineral admixtures such as silica fume, slag, fly ash, and metakaolin, on the mechanical behavior of young concrete under either uniaxial compression ...

Abstract: Owing to their importance to the structural analysis and evaluation of cement-based materials, it is essential to determine the mechanical properties of cement paste. This paper presents a simple three-step analytical ...

Abstract: Owing to its importance to the structural analysis and design of cement-based materials, it is essential to determine Young’s modulus of concrete. This paper presents a numerical method for predicting Young’s modulus of ...

Abstract: In this paper, a two-step model is proposed to predict the effective chloride diffusivity of cement paste and cement mortar. The prediction effective chloride diffusivity results of cement paste and cement mortar are ...

Abstract: The electrical resistivity of hardened cement-based materials was measured in this work by a modified noncontact electrical resistivity measurement (MN-CM). The resistivity was further processed to compute the chloride ...

Abstract: This study utilized a heat-moisture coupling model to characterize the internal microenvironment of concrete and establish the relationship between environmental temperature, humidity, external chloride ions, corrosion ...
