water retentivity การใช้

• Water retentivity of mortar
• Standard test method for water retentivity of grout mixtures for preplaced - aggregate concrete in the laboratory
• Testing of mortars containing mineral binders ; determination of water retentivity of freshly mixed mortar by the filter plate method
• The binders has supper fluidness 、 bonding capacity 、 water retentivity 、 filler properties , no segregation , no bleeding and supper mechanical properties after harden . it is one of high performance concrete . japanese have been researched self - compacting concrete from 1987 , and used more than 1 . 2millions litres
• Dsc for the nanocomposites showed the glass transition temperature ( tg ) of the nanocomposites increases slightly as the mmt content increases . water absorption velocity and water retentivity under pressure tests showed the addition of montmorillonite ( mmt ) can improve the beginning absorption velocity and water retentivity for pure superabsorbent resin
