Abstract

A device and method to detect the interface bond strength of rubber aggregate and cement stone belong to the building material test field. One end is used the circle-bed rubber mass which the material is as same as rubber aggregate in concrete; the suspension link is fixed on the big diameter surface which is connected with the salver of the other end; the small diameter surface of rubber mass iscovered with the interface finishing agent, which is embedded into the new mixing cement. When it reaches the ordain test period, the salver is added with the weights until the rubber mass is separated from the cement surface, so the pull force can reflect the interface bonding strength of the rubber aggregate and cement. The test method can simulate the real environment condition of bonding and avoid the traditional error; also it can reflect the bonding character between the rubber material and cement.

Description

technical field The invention belongs to the technical field of building material testing. Specifically, it is a device and method for testing the interface bond strength between rubber aggregates and cement stones. The test principle of this method is scientific, the test process is simple and convenient, and the test results can accurately reflect the relationship between rubber particles and cement stone matrix in rubber aggregate concrete. interfacial bond strength. Background technique Rubber aggregate concrete is prepared by crushing waste tires into rubber particles and adding them to cement concrete, which has the advantages of good toughness, impact resistance, shock absorption and shock resistance, light weight and heat preservation, noise reduction and sound insulation, breathable and water permeable, etc. However, the strength of rubber aggregate concrete is low, which limits its engineering application to a certain extent. At present, an important method to imp...
