Study on the influence and mechanism of rubber on the properties of ultra-high performance concrete
In order to address the issue of protecting the environment from rubber waste,this study uses rubber particles as filler aggregate to create ecotypic ultra-high performance con-crete(UHPC).The results indicate that the rubber content and particle size have a substan-tial impact on the structural breadth and porosity of the interfacial transition zone(ITZ)of UHPC,resulting in varying UHPC degradation effects.Using working performance and strength as the dependent variables,the ideal dose(10%)and particle size(0.850 mm)of rubber particles are found,and an ecotypic UHPC with a compressive strength of more than 120 MPa is created.This research provides suggestions for the recycling of rubber.
