This study presents the measured results during the whole process of deformation and also the values of cracks and ultimate strengths of 40 reinforced ceramsite concrete beams of rectangular section under short-term loading. The curves showing the whole process of strain, curvature and deflection in 4 beams are given as examples. In a table, the measured values of deflection and crack width of the 40 beams under one stage of loading are given. The authors suggest formulas for calculating stiffness and crack similar to those recommended in the current Code. The results calculated by the proposed formulas agree satisfactorily with the measured values. The test results of moments at first cracking and the ultimate strength are also given. Finally, curves showing the increase of deflection and crack width with time of 6 beams under long-term loading sustained for three months are presented, and predictions of their final values are also made.
