Abstract:

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.
