A composition for forming fire resistant concrete block, that includes a cementitious binder material comprising alumina cement, recycled fine aggregate, and recycled coarse aggregates, the recycled fine aggregates including 10-50 wt % recycled particulate glass cullet having a particle size of 600 microns or less, a concrete block formed from the composition exhibiting a decrease in thermal conductivity with increasing temperature at temperatures causing the particulate glass cullet to melt. A concrete block fabricated from the composition exhibits a fire resistance of at least three hours, a density below 2000 kg/m, and a compressive strength of at least 7 MPa.
