Study on the Influence of Organic Fiber and SBR Latex on the Bending Properties of Rubber Mortar

摘要

This paper deals with the investigation of the bending properties of rubber mortar with the inclusion of SBRL (butylbenzene latex) and PP (polypropylene) fiber. The results proved the elasticity modulus of modified mortar decreased, especially when modified materials groups were SBRL10 %+R30%+PP, the elasticity modulus of mortar was minimum and the flexibility was the best. The deflection increased with the inclusion of modified materials, especially when 30 vol.% of rubber was included in mortar. The specimens containing 20 vol.% of rubber exhibited post failure loads and the peak load of polypropylene fiber and SBR latex modified rubber mortar with 20 vol.% of rubber grew, whether specimens were included with polypropylene fiber or not.
