Mechanical Effect Study on Modified Rubber Particles Cement Mortar and Mechanism Analysis

Abstract:

Interface bonding is the key technical problems of waste rubber in engineering application. Studies show that, with the increase of unmodified rubber particles dosage, the cement mortar 28 d compressive and flexural strength significantly reduce; when NaOH modified rubber particle content is less than or equal to 5%, it can reduce the compressive flexural strength reduction; The PVA modified rubber particles had no beneficial effect on the strength; rubber particles modified by silane coupling agent KH560, can greatly improve the rubber cement mortar 28 d compressive and flexural strength; the modifier mechanism is studied by scanning electron microscopy (SEM).
