In order to better understand the impact of glass waste on the properties of the waste-glass concrete [111,112,113,114]. Omoding, Cunningham and Lane-Serff investigated the concrete microstructure via SEM by replacing between 12.5– of the coarse aggregate with green waste glass with a size of 10–20 mm. The authors stated …

As compared to natural aggregates (NA), reused concrete aggregates (RCAs) made from demolition and construction waste often have higher absorption capacities. In case of M30, RCA with the substitution up to 30% of NA along with cement content of 438 kg/m 3 is appropriate for structural construction.
