Initial assessment of the possibility of using glass waste coming from worn-out fluorescent lamps as aggregates for cement concrete

Abstract

The paper presents preliminary analyzes of the possibilities of using glass waste from extruded fluorescent lamps as aggregates for cement concretes. The research material was obtained from a company that utilizes electrical waste. Glass from pre-sorted lighting elements was transported to the laboratory and crushed in a steel mortar. In this way, the aggregate obtained was subjected to the basic tests that are carried out for aggregates traditionally used in construction. The specific density of aggregate, bulk density, absorbability, grain shape and texture type were examined. In the next stage of research work, a concrete mix was made, in which, as a substitute for 25% gravel aggregate, crushed aggregate from crushed fluorescent lamps was used. The compressive and tensile strength of the concrete thus formed was tested. Analysis of the test results showed that broken glass from worn out fluorescent lamps can potentially be used as an aggregate for cement concrete.

Evaluation of Traditional Container Glass Recycling Systems Against Selected Environmental Impact Criteria Using the LCA Method

“…adaptation of wastes, to which they are subjected in the recycling processes, proves that they are often detrimental to the environment. Recovery of some materials can be difficult and costly, whereas transport is not very profitable [Zegardło et al 2018]. Washing the waste consumes valuable water resources.…”
