WASTE GLASS AS COARSE AGGREGATE FOR CONCRETE

Performance of 34 different concrete mixes containing glass crushed to three-quarters of an inch (19-mm) maximum size as coarse aggregate and six reference mixes made with gravel of the same size is recorded. Partial cement replacement with fly ash and mixing of glass with gravel aggregate were included in an attempt to find a suitable method of overcoming the expected adverse effects of the reaction between glass and cement alkalis. On the basis of compressive strength, flexural strength, expansion, and visible surface deterioration recorded up to an age of one year, the results show that in many cases the direct combination of glass with portland cement yields concrete which exhibits marked strength regression and excessive expansion due to alkali-aggregate reaction. The conditions under which performance is satisfactory appear to relate to limiting maximum values of cement content and alkali equivalent.
