To enhance the mechanical properties and damage resistance of prefabricated monolithic composite beams, this study introduces HPFRCC precast mold shells as a replacement for ordinary concrete in construction beams. These shell beam members are then subjected to experimental investigations analyze their flexural properties. The results indicate that U–shaped exhibits excellent bonding with post-...

This paper presents the experimental results of an on-going research project on geopolymer lightweight concrete using two locally available waste materials--low calcium fly ash (FA) and oil palm shell (OPS)--as the binder and lightweight coarse aggregate, respectively. OPS was pretreated with three different alkaline solutions of sodium hydroxide (NaOH), potassium hydroxide, and sodium silicate...
