Preparation and Properties of Alkali Activated Foam Cement Reinforced with Polypropylene Fibers王立久,谭晓倩Institute of Building Materials,School of Civil and Hydraulic Engineering,Dalian University of Technology摘 要:A new form of foam cement was produced by mixing alkali-activated slag,clay,a small amount of polypropylene fibers with prepared foam during......
Three Dimensional Microstructure and Image-Based Simulation of a Fly Ash/Al Syntactic Foam Using X-ray Micro-Computed Tomography张强,WU GaohuiSchool of Materials Science and Engineering, Harbin Institute of Technology摘 要:An aluminum matrix syntactic foam, incorporated with hollow-structured fly ash particles, was fabricated by pressure infiltration......
surface is limited. It is acknowledged that aluminum foam is a kind of closed cell porous metal, so gas is enclosed in each independent cell. Accordingly, we believe that bubble surface cannot react..., the critical oxygen volume fraction needed to produce aluminum foams with good cell structure and the role of oxide film in foam stability have not been reported. In order to improve the gas injection foaming......
