- The use of steel slag as a substitute to natural aggregates for concrete increases the compression strength and workability of fresh concrete mixes. Furthermore, by solidification in the cement matrix, the pollution of heavy metals into soil and groundwater can be reduced significantly. The utilization of slag-concrete to be used as structural components need to be conducted especially since mass density increases as a function of slag percentage. Possible aspects are among others, basement components, tie-beams and rigid pavement elements. All these structures rest directly on supporting under layers, reducing their negative high mass-density effect. While compression and tensile behavior have been explored, the shear capacity of slag-concrete has yet to be investigated. This experimental work covers the behavior of singly reinforced concrete beams failing under shear mode. The result is compared to the controlling element, identical to the concrete-slag beam. The controlling beam uses Pudak Payung aggregates. The experimental research shows that the slag-concrete’s shear capacity increases 11% to the Pudak Payung concrete. The mode of failure however, remains the same. Keywords: slag, coarse aggregates, compression and shear strength.
