چکیده:

This paper presents the fresh and mechanical properties of Self-Consolidating Lightweight Concrete (SCLC) containing Natural Zeolite (NZ) assessed by means of slump flow, flow time, V-funnel, L-box, column segregation, compressive strength and cross-section image tests. The test results indicate thatincorporation of NZ generally improves mechanical and rheological characteristics of the concrete mixtures. In the hardened state, by increasing NZ, the compressive strength was increased up to 14% and 25% at the age of 7-days and 28-days, respectively. In addition, the results show that NZ enhancedaggregate segregation of SCLC. In addition, the viscosity of SCLC increased when the percentage of NZ increased. As the results of column segregation and L-box tests show, segregation resistance ability was increased by higher proportion of NZ and finally segregation resistance and passing ability were increased at higher proportion of NZ and finally segregation was qualified in mixture with 12% NZ.
