The search for new techniques to strengthen the bond between the aggregates and mortar
at the interfacial zone still remains a challenge. In this study we introduce a new technique
of strengthening the inter phase between cement paste mortar and aggregate through
confinement of fresh concrete with application of mild load axial loading, this will reflect
on developing better bonding within the concrete matrix . Physical and mechanical
investigations indicate that, this technique has a strong potential and could double
production rate of precast concrete members. Further investigations regarding the
microstructure analysis using Scanning electron microscope and (Energy Dispersive X-ray
Analyses) were also conducted.
