TL;DR: In this paper, the pore structure of magnesium potassium phosphate (MKPC) paste was investigated using mercury intrusion porosimetry and several mix proportions, obtained by changing the magnesia-to-phosphate molar ratio (M/P ) and the water-tocement mass ratio (W / C ) of the material, were involved.

TL;DR: The results showed that, compared to the AAFA, blending 10 % metakaolin in AAFA significantly improved both 28-day and 90-days compressive strengths, which was almost 200 % higher than that of AAFA.

TL;DR: In this paper, an experimental study was carried out with the aim of understanding the interacted mechanism between carbonation and chloride aerosol attack in ordinary Portland cement (OPC) concrete, and the effects of carbonation on the chloride profile, the chloride binding capacity and the chloride diffusion coefficient were evaluated.

TL;DR: In this article, a comprehensive investigation regarding the chloride transport and microstructure of plain concrete and fly ash blended concrete under atmospheric chloride environment is presented, and a linear relationship between the total and free chloride content is observed.

TL;DR: In this paper, the coupled effect of carbonation and chloride aerosol ingress on the durability performance of fly ash concrete is investigated, and it is shown that carbonation significantly affects the chloride ingress profile, reduces the chloride binding capacity, and accelerates the rate of chloride ion diffusion.
