The density function theory and discrete variation method(DFT-DVM) was used to study correlation between composition, structure, chemical bond,and property of t
This paper discussed the preparing process of hydroxyapatite fibers which were widely used as reinforcement for biomedical materials by homogeneous precipitatio
The frost durability of concrete is considered from structural engineering points of view.Specific failure process is analyzed and a damage model is established
The overall aim was to investigate the effect of highly active rice husk ash (RHA) produced by an industrial furnace on some properties of concrete. The strengt
