"The Effects of Petroleum Products on Reactive Powder Concrete Using Waste Glass as a Partial Replacement for Fine Aggregate"
Rawaa K. Aboud
Abstract: The aim of this research is to study the effect of partial replacement of river sand with glass wastes on some of the mechanical properties (compressive strength, flexural and absorption) of reactive powder concrete (RPC). Moreover, the effect of curing the samples has been studied by using two types of curing (water and kerosene). RPC was designed using local cement, silica fume, and super plasticizer with a water/cement ratio of (0.2) to reach a compressive strength of (70 MPa) at the age of (28 days). (58 cubes) and (48 prisms) have been casted and tested with four percentages of glass wastes replacement (0%, 25%, 50%, and 100%). The results showed that the (25%) of glass wastes replacement increased the compressive strength of RPC up to (4.35 and 2.6) % and the flexural strength up to (4 and 2.2) % for both methods of curing (water and kerosene) respectively. A reduction in the compressive strength, flexural strength, and absorption has been produced when the percentage of glass wastes was increased more than 25%. Furthermore, the results showed that the mechanical properties of samples cured in oil product (kerosene) were reduced when compared to those cured in water.
