Aggregate Replacement - an overview ScienceDirect Topics

When used as sand replacement, there is some indication that there can be a noticeable reduction in compressive strength (CCAA, 2008). This is, however, not consistently observed (Oliveira et al., 2008; Sangha et al., 2004; Limbachiya, 2009; Taha and Nounu, 2009). The main issue with waste glass sand in concrete is the risk of potential alkali ...
