Abstract

This study evaluated the effect of foam volume ratio on shear friction behavior of bottom ash based lightweight aggregate concrete (LWA_BA). The LWA_BA with different foam volume ratio ranged between 8 and 25 MPa for compressive strength(fck), 17.3~62.5 kN for shear capacity at first shear crack(Vcr), 31.1~73.8 kN for shear friction capacity(Vn), and 0.01~0.03 mm for slip at maximum peak load(S0). fck decreased with increase in the foam volume ratio, showing that this trend was also observed in Vcr, Vn, and S0.
