Producing Load Bearing Block Using LECA as Partial Replacement of Coarse Aggregate

The ability to produce load-bearing masonry units adopting ACI 211.1 mix design using (1:3.2:2.5) as (cement: fine aggregate: coarse aggregate) with slump range (25-50mm) which can conform (dimension, absorption, and compressive strength) within IQS 1077/1987 requirements type A was our main goal of the study. use low cement content (300 kg/m3) handle market price products since most consumption in wall construction for low-cost buildings encouraging. (10 20%) LECA partial volume replacement aggregate reduce huge weight blocks also be recommended. types production were B 20%), respectively. Finally, spray curing method more suitable simulation reality easier factory producers, taking into consideration that increasing time from 14 days (recommended 1077/1987) 28 may led conversation R20%-300.
