  • comparison of mechanical and physical properties of sbr polymer modified mortars using recycled waste materials
    Journal of Industrial and Engineering Chemistry, 2008
    Co-Authors: Euihwan Hwang, Young Soo Ko

    Abstract:

    Abstract Polymer modified mortars using either recycled waste concrete fine aggregate (WCFA) or Artificial Marble waste fine aggregate (AMWFA) were prepared and investigated for the purpose of feasibility of recycling. The replacement ratio of recycled materials also changed to investigate the effect of it on mechanical and physical properties. The water–cement ratio was increased as the replacement ratio of either AMWFA or WCFA in mortar in the absence of styrene-butadiene rubber (SBR) latex. The presence of SBR for both WCFA and AMWFA gave the increase of the air content. The compressive strength decreased in the presence of SBR. The higher replacement ratio of WCFA and AMWFA lowered the compressive strengths significantly. The compressive strength of AMWFA was significantly lowered after the hot water resistance test, whereas that of WCFA was slightly increased after the hot water resistance test. As the replacement ratio of either WCFA or AMWFA increased, the flexural strength decreased as well as compressive strength.

  • effect of polymer cement modifiers on mechanical and physical properties of polymer modified mortar using recycled Artificial Marble waste fine aggregate
    Journal of Industrial and Engineering Chemistry, 2008
    Co-Authors: Euihwan Hwang, Young Soo Ko, Jongki Jeon

    Abstract:

    Abstract Various polymer-modified mortars using recycled Artificial Marble waste fine aggregate (AMWFA) were prepared and investigated for the purpose of feasibility of recycling. Styrene–butadiene rubber (SBR) latex and polyacrylic ester (PAE) emulsion were employed as polymer modifier, and compared each other. The replacement ratio of AMWFA was also changed to investigate the effect of it on physical properties. Adding polymer cement modifier into mortar reduced water–cement ratio, and PAE was the more effective polymer cement modifier to reduce water–cement ratio than SBR. PAE emulsion-modified mortar increased the air content entrained as the proportion of PAE was increased. There was little difference in water absorption between SBR latex and PAE emulsion. The compressive strength decreased in the presence of polymer cement modifiers compared to that of no polymer cement modifiers, but the compressive strength of 20% of polymer–cement ratio was higher than that of 10%. After the hot water resistance test, both compressive strength and flexural strength were decreased.

  • comparison of physical properties of pae polymer modified mortars from recycled waste Artificial Marble and waste concrete fine aggregates
    Journal of Industrial and Engineering Chemistry, 2007
    Co-Authors: Euihwan Hwang, Taeksung Hwang

    Abstract:

    In this study, we compared the properties of PAE (polyacrylic ester) polymer-modified mortars pre- pared from recycled waste Artificial Marbles and waste concrete fine aggregates. We used PAE emulsion as a polymer modifier; 30 types of specimens of polymer-modified mortars were prepared by varying the pro- portions of the polymer modifier and the recycled fine aggregates. To evaluate the properties of the poly- mer-modified mortars, we determined the air contents, water-cement ratios, unit weights, water absorptions, compressive strength, flexural strength, hot water resistance, and pore volumes. The compressive and flexural strengths of the specimens decreased upon increasing the replacement ratios of the recycled fine aggregates, while they increased upon increasing the additive amount of the polymer modifiers. For the specimens that were prepared from waste Artificial Marble, the compressive and flexural strengths of the specimens, de- termined after hot water resistance testing, were decreased significantly. The pore volumes, determined after hot water resistance testing had decreased.
