The Utilisation of Recycled Concrete Aggregate as Partial Sand Replacement in Wall Panel Production

Recently, extensive research within the concrete industry has been devoted to a sustainable approach by using waste as natural aggregate replacement. The reason is that volumes of building-related generated nowadays are becoming significant threat environment but they may be used useful material in construction industry. Hence, this study aims investigate effects recycled aggregates partial fine replacement mortar cubes and wall panels. Mortar panels sized 70.7 mm x 1000 300 100 mm, respectively, were prepared. was mixed into at percentages 0%, 50% 100% total volume designated 0RCA, 50RCA 100RCA, respectively. samples both assessed under compressive strength test. tested ages 3 days, 14 days 28 days. Meanwhile, compressively loaded for more than It found 0RCA represented highest compared other 100RCA 46.6% 38.8%, ultimate load 203.26 kN with effectiveness 179.75% This indicates can production
