Concrete compositions containing glass powder with a particle size between 1mm and less than 35 microns

摘要

A concrete composition comprises a Portland cement mix, coarse and fine aggregate, water and glass powder having a particle size distribution between 1mm and less than 35 microns, with more than 30% being less than 45 microns and 10% less than 35 microns. The Portland cement mix may comprise none, one or more of: pulverised fly ash, ground granulated blast furnace slag, metakaolin, silica fume and rice husk ash. The coarse and or fine aggregates may include glass aggregates. The concrete may also include a super-plasticiser.
