Effect of Thermal Cycles and Curing Age on Bonding Strength of Cement Mortar Using Manufactured Sand
Publikováno v:
Buildings, Vol 14, Iss 3, p 783 (2024)
The bonding of cement mortar to the concrete substrate is crucial in buildings. In this study, cement mortar was prepared using manufactured sand (MS) instead of river sand (RS). The bonding strength between manufactured sand mortar (MSM) and concret
