Flexural strength of special reinforced lightweight concrete beam for Industrialised Building System (IBS)

Special reinforced lightweight aggregate concrete (SRLWAC) beam is designed as beam component in Industrialised Building System (IBS). It is used to overcome the difficulties during the component installation due to the heavy lifting task. This paper presents the flexural strength and performance of...
