Abstract :
On the basis of adopting the natural pumice as coarse aggregate and to compound LC40 strength class of lightweight aggregate concrete, this paper studies the workability , compressive strength, flexural strength and axial compressive strength physical and mechanical properties of lightweight aggregate concrete affected by different dosage fly ash, and from microcosmic structure is analyzed. The results show that mixed limestone powder could ameliorate mixing resistance and physical and mechanical properties of lightweight aggregate concrete more obvious; and dosage limestone powder with 30% is the best for the mechanical properties of lightweight aggregate concrete.
