Study on the Influence of Polypropylene Fiber and SBR Latex on the Static Strength of Rubber Mortar

Abstract:

This paper deals with the investigation of the static strength of rubber mortar with the inclusion of two macromolecules: SBR (butylbenzene) latex and PP (polypropylene) fiber. The rubber mortar were produced with the inclusion of SBR latex and PP fiber. The characteristics were performed by testing the compressive strength, flexural strength and the C/F (it refers to the ratio of compressive to flexural strength). The results proved that compared to conventional mortar and rubber mortar, the C/F (lower C/F means better flexibility) of SBR latex modified rubber mortar decreased and its flexibility significantly enhanced. The rubber mortar with 2.5% P/C (it refers to the ratio of polymer-cement) of SBR latex performed best in flexibility and the flexibility of rubber mortar with 30% rubber particles proportion was better than the 20% counterparts. The C/F of PP fiber and SBR latex modified rubber mortar was minimum with 7.5% P/C (20% rubber particles proportion groups) and 2.5% P/C of SBR latex (30% rubber particles proportion groups).
