Aggregates Portland Cement Association

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.

Best Practices in Glass Recycling End-Use Applications / Portland Cement Page 2 of 2 BP-GL4-05-01 entrainment system, which incorporates evenly dispersed microscopic pockets of air in the PCC. When ASR occurs, these air pockets allow additional space for the gel to expand, thereby lessening the potential for structural weakness.

Potential for Using Waste Glass in Portland Cement

Local recycling pressures are providing an impetus to examine the use of unconventional materials in construction such as waste glass in Portland cement concrete. It is well known that the silica in glass can be highly reactive with the alkalis in cement paste and that this reaction can lead to expansion and cracking of the concrete (alkali-silica reaction or ASR).
