Abstract :
In this research study the performance of pre-wetted sawdust as a source of internal curing for
concrete was investigated. Primarily sawdust was used to reduce self-weight of concrete, however it was
recognized that dry porous sawdust could absorb sufficient amount of water that could be an effective mean of
internal curing. Pre-wetted sawdust was used to partially replace the sand and specimens were covered in
polythene bags. Different trials were performed on sawdust lightweight concrete with internal and external
curing and tested for compressive strength. Compressive strength results were compared with normal density
concrete to draw conclusions.
