Testing of Glass Product as Construction Aggregate
Laboratory evaluation of the glass aggregate for suitabilty as construction aggregate in concrete and asphalt was done in Clemson’s Civil Engineering Department .
- Concrete testing included compressive, flexural, abrasion and air entrainment. Compressive concrete testing indicates (per ACI-211 procedures) that up to 15% of the glass product can be added without compressive strength failure, with results still a minimum of 50% over the test requirements. Bending strength shows the glass aggregate to be stronger than control samples, even at 15% replacement.
- Asphalt testing included abrasion, plastic flow, compaction, absorption, and cohesion. Tensile strength ratio values were above the minimum test requirements. As a whole, all of the asphaltic testing indicates that at least 5% replacement of traditional aggregates with the glass product is satisfactory.
