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
Colloidal silver particles are formed on float glass by heat treatment with coated silica film containing Ag by sol-gel process . The Sn2+ on surface of float g
Al-induced lateral crystallization of amorphous silicon thin films by microwave annealing is investigated. The crystallized Si films are examined by optical mic
