A Study of Strength Characteristics of Recycled Glass (Cullets) in Concrete Floor Tiles Prodution

Aikulola O.A, Sanni H.A.


The utilization of recycled glass in construction, such as its application in highway pavement construction, concrete oversite and flooring has been occurring over the past couple of decades. In recent years, the discovery of several economic and environmental benefits has increased the use of recycled glass most especially in highway construction and precast concrete members such as wall panel, table tops and so many other concrete products, making the evaluation of the properties of glass and aggregate mixes necessary. The uses of recycled glass are varied depending on the specific application. Crushed recycled glass, or cullet, has been independently, and has also been blended with natural stone aggregate at different replacement rates. The research provides an evaluation of the potential use of glass cullet when used in combination with natural coarse aggregate for slab construction. This research studied the strength and the density characteristics of different glass-aggregate blend to examine the effects of blending glass cullet into concrete by partial replacement of the coarse aggregate. A source of natural aggregate was tested,’ GRANITE’ it being crusher run and very angular in nature. The glass was introduced into the concrete mix at the replacement rates of 20%, 40%, 60%, 80% and 100% the maximum size of glass cullet is 20mm.
