the benefits of using mineral admixtures as a partial replacement of portland cement (pc) are well established in the literature. economic and environmental advantages by reducing co2 emissions are well known. this paper examines the influence of intergrinding and separate grinding on the amount of energy consumption, blaine fineness and particle size distribution (psd) of blended cements, name...

gold nanoparticles were synthesized by chemical reduction of haucl4 inside the pores of a polycarbonate-based membrane followed by dissolving the membrane in dichloromethane and further sonication. sonication time as the main affecting factor on the nanoparticle size was investigated. the characterization by transmission electron microscopy showed the formation of gold nanoparticles with diamet...
