Çimento Hamuruyla Kaplanmış Pomza Agregalarının Su Emme ve Darbe Dayanımı Performanslarının İncelenmesi

Pumice aggregate, which has high reserves in our country, is used the production of lightweight concrete, however, it not preferred as a structural concrete since its low mechanical properties. The properties pumice aggregates can be improved by coating their surfaces. In this way, coated to produce concrete. This study investigated potential Kayseri and Ahlat with cement paste. flow diameter, marsh funnel, 28-day flexural compressive strength values paste 0.55-0.50 w/b ratio 0.35-0.30 1.5% plasticizer admixture were determined. At end curing, Coating effectiveness produced samples was via optical microscope, aggregate impact value, water absorption, unit weights, comparisons made uncoated aggregates. After coating, determined that crushed 11% 18%, considering result, moreover decrease absorption obtained 50.49% 78.32%, respectively. As decreased, increased compared
