Abstract

With finely ground waste cathode ray tube glass sand, respectively replace 20%, 40%, 60% the proportion of ordinary sand in mortar, fly ash as mineral admixture in 0%, 10%, 20%, 30% the proportion of replacing cement.A total of 12 sets of mortar specimens were prepared.Use Accelerated Mortar Bar Test (ASTM1260) to measure mortar specimens alkali aggregate reaction expansion at 3D, 7D, 14D, 28D.The results show that: CRT glass is an alkali active substance, expansion will become larger with the increase of CRT glass content in the mortar specimen. Fly ash can restrain CRT glass mortar ASR expansion, all adding fly ash specimens 14D expansion rate is less than 0.1%, the swelling degree of restraint increases with the fly ash, ash up to 20% when we have been able to significantly restrain the expansion.
