Luo Binqi from Tianjin University's paper "Research on Crack Resistance and Bending Toughness of Rubber Aggregate Concrete" is mainly divided into five modules. First, the status quo of rubber aggregate concrete, the causes of crack types and protective measures are introduced, and then the improved ring test method is adopted. To analyze the anti-crack performance of the clean slurry and mortar specimens with different rubber content, it is concluded that the thickness of the rubber mixed delays the cracking of the specimen and reduces the width of the crack. Then carry out the creasing test on the clean slurry and the mortar respectively. Furthermore, the new-type plate method was used to analyze the crack resistance of concrete with different rubber content, and it was concluded that the addition of rubber delayed the appearance of the first crack, and reduced the width of the crack and the total cracking area. Finally, the early flexural toughness of concrete with different rubber content was studied, and it was found that the incorporation of rubber particles improved the brittleness of concrete and produced a large deformation when it was damaged.
