Abstract In this research, the particle size distribution (PSD) of different components in inter-ground Portland limestone cement (PLC) and limestone-slag cement (PLC-S) was characterization by using an electron microscopy ...
Abstract This paper presents an analytical model for calculation of corrosion induced stress field and cracking time of concrete cover with initial defects in a reinforced concrete. In the proposed model, two types of ...
Abstract The inorganic salt hydrate PCM, CaCl2·6H2O, has a promising potential for thermal energy storage. However, this salt hydrate has tremendous issues of supercooling (the supercooling degree was 25.5°C as found in ...

Abstract CFS members are more vulnerable to fire due to high section factor (fire-exposed area to the heated volume). Hence, an extensive review of experimental and numerical studies performed on CFS beams and columns at ...
Geothermal energy piles are a quite recent renewable energy technique where geothermal energy in the foundation of a building is used to transport and store geothermal energy. In this paper, a structural–functional integrated ...
Abstract In this research, a micro X-ray computed tomography (μCT) technique was used to investigate the distribution of steel corrosion embedded in cement paste non-destructively. An electrochemical method was used to ...
