Research on Influences of the Coarse Aggregate Size on the cracks of the reinforced beam
This paper gives the influences of the coarse aggregate size on the cracks of the beam with different aggregate sizes under static loads.The coarse aggregate sizes are ranked into three classes:small size (4.75mm ~ 19mm),big size (19mm ~ 37.5mm) and mixed size (4.75mm ~ 37.5mm).The developments of cracks of three reinforced concrete beams with the different of coarse aggregate sizes under the static loads are researched.The results show that under the action of the same loads,The reinforced concrete beams with the big aggregate size and mixed aggregate size have almost the same maximum crack width,while the maximum crack width of the beam with small aggregate size is less than formers.Using fractal theory,the fractal dimension of the cracks is studied.The result shows that the aggregate sizes have significant effect to the cracks on the reinforced beams.
