Mechanical Properties of Tin Slag Mortar

The increased demand for cement mortar due to rapid infrastructural growth and development has led an alarming depletion of fine aggregate. This prompted the need a more sustainable material as total/partial replacement natural study proposes use tin slag (TS) aggregate in concrete bridge this sustainability gap. TS was used replace at levels 0%, 25%, 50%, 75%, 100% mortar. Fresh hardened properties were obtained. Flow tests showed that, quantity w/c ratio increased, flow increased. Similarly, compressive strength up 50% replacement, after which decline observed. However, with 100%, 6% above control attained. morphological features confirm that specimens had denser microstructure because its shape characteristics (elongated, irregular, rough), and, thus, plugged holes better than sand’s contribution result hardness compared TS. Hence, can be alternative construction.
