Abstract:
Mix proportions for self-compacting lightweight concretes(SCLC)were chosen by formulas for the water content of overall calculation method and fixed volume content of aggregate method. On the basis of the parameters of flowing diameter and L-box, optimizing mix proportions for SCLC40 and SCLC50 were designed. The parameters of principal mechanical properties of SCLC, such as compression strength, cleavage extension strength, creasing resistance and elastic modulus were analyzed, and the basic mechanical properties of SCLC were compared with normal concrete. The results show that SCLC has higher strength, better tenacity and smaller elastic modulus and so on. The result provides a reference for the project application of SCLC.
