The bending tests of 5 ceramsite concrete beams and 1 ordinary concrete beams were carried out.The effects of ceramsite strength and particle size on the crack and ductility of concrete beams were studied.The results show that the energy dissipation and ductility of ceramsite concrete beams are better than those of ordinary concrete beams,the strength and stiffness of ceramsite concrete beams are slightly lower than the ordinaio concrete beams.When the size of ceramsite is the same,the higher the ceramsite strength,the smaller the number of cracks in the ceramsite concrete beam,and the less en...
