The usage of fluorescent waste glass powder in concrete

Abstract

Typical problem for Baltic States is recycling of glass; glass wastes are mainly dumped into landfill. Landfills of nonrecyclable fluorescent lamp glass do not provide an environmentfriendly solution for these wastes. In the present research waste borosilicate (DRL) and leaden silicate (LB) glass chippings after fluorescent lamp crushing were ground and used as micro filler as partial substitution of cement therefore reducing landfill pollution and CO 2 emissions into the atmosphere. Waste glass powder additional grinding time was in the range of 30min to 90min in order to increase fineness. Superplasticizer was used in order to raise compressive strength of concrete.

Performance of waste glass powder (WGP) supplementary cementitious material (SCM) – Workability and compressive strength

“…It was demonstrated on concrete specimens [14] that WGP addition improves workability and results a soft er consistency (demonstrated by standard slump tests), can contribute to the compressive strength of the hardened concrete and due to the relatively high specifi c surface area (maximum particle size was found to be smaller than 200 μm in each case [13]) they have a relatively small infl uence on ASR expansion.
