Study on the Influence of Form Factor of Abrasion Particles on Concrete
The form factor of abrasion particles is one of the most important Influencing factors of abrasion resistance of concrete. In order to evaluate the serves life of concrete, a relationship about the form factor of abrasion particles and the wear degree of abrasion resistance of concrete should be established. In this paper, wear process of basalt on concrete was studied under the flow velocity form 1.7m/s to2.4m/s by a improved under water method test equipment. Meanwhile, an image acquisition method was used to get the form factor of basalt to measure the influence of form factor of basalt on wear degree of concrete. The result shows: the abrasion rate of concrete is higher when the flow velocity is faster and the particle form is sharper, and there is an exponential function relationship between particle forms and abrasion rate.
