Description
Summary:This investigation presents the influence of different environmental exposures on splitting tensile strength of long term cured Tin Slag Polymer Concrete (TSPC). Cylindrical TSPC specimens were moulded with tin slag and unsaturated polyester resin in the ratio 30:70 and exposed to indoor, outdoor and industrial environments. After 12 months of exposure, they were tested for its splitting tensile strength characteristics. The TSPC samples exposed to industrial (aggressive) environment reads an average value of 10.36 MPa. On the other hand, TSPC samples exposed to indoor (controlled) and outdoor (tropical climate) environments depict an average value of 7.92 MPa and 8.37 MPa respectively. Failure modes of TSPC for long term curing revealed splitting of sample along diametrical line with some parts peeling off from the middle section. Analysis of the stress-strain data revealed that all TSPC specimens exhibited linear behavior up to the peak load. Beyond this point, the specimens continued to fissure without additional strain. This behavior indicates a perfectly brittle failure mode which makes them suitable for structural applications. These findings support sustainable construction practices by promoting resource efficiency and delivering economic benefits to society.
