基于热力学模拟的碱激发材料物相演变与耐久性能研究进展

Alkali-activated materials (AAMs) are one of green cementitious materials in building materials industry and beneficial to the goals of carbon peaking and carbon neutrality. Compared with ordinary Portland cement (PC) based materials, however, the raw material composition, reaction products and pore solution composition of AAMs are complex...

Transport Properties of Carbon-Nanotube/Cement Composites

This paper preliminarily investigates the general transport properties (i.e., water sorptivity, water permeability, and gas permeability) of carbon-nanotube/cement composites. Carboxyl multi-walled carbon nanotubes (MWNTs) are dispersed into cement mortar to fabricate the carbon nanotubes (CNTs) reinforced cement-based composites by applying...

Advances in chloride diffusion of concrete exposed to marine field environment

For elaborating the research significance, goal, content and representative results of the concrete marine field exposure experiments all over the world, we have collected a large number of research literature since 1905. The longest exposure test for concrete has reached 62 years and, most importantly, concrete exposure experiments have made...
