... as microstructural development has not been fully understood. In this study, natural clinoptilolite zeolite replaced portland cement at 0, 5, 10, 15, and 20 % by mass as a supplementary cementitious material. Particle size distribution and mineral phase identification of zeolite particles were done by laser...

... distribution because of the ultrafine sizes of the metakaolin. The results were confirmed by microstructure analysis such as scanning electron microscopy/backscattered electron image, X-ray diffraction, and differential thermal analysis/thermogravimetric analysis conducted on hardened cement paste...

...Nima Farzadnia In this study, the effects of halloysite nanoclay (HNC) on cement mortars after exposure to elevated temperatures were investigated. The compressive strength, microstructure, and chemical composition of mortars with 0 %, 1 %, 2 %, and 3 % HNC were compared after exposure...

.... Specifically, the experimental study presented in this article is aimed at investigating the effects of chlorides in the raw materials on the durability-related properties of concrete. To this purpose, different concrete mixtures with chloride-contaminated materials were tested in terms of microstructural...

...)). Experiments were designed to measure the absorption capacity and kinetics of hydrogel particles immersed in pure water and cementitious pore solution, as well as determine the impact of particles on cement paste microstructure. While majority-AM hydrogel particles displayed relatively stable absorption values...

.... These admixtures modify the microstructural characteristics of SCC, which in turn affect the mechanical and fracture properties of concrete. In this study, an attempt has been made to establish the relationship between the microstructure and fracture properties of SCC mixes. The fracture properties are studied...
