The aim of this experimental study is to investigate the effect of steel fibers on the compressive strength of cement mortar at elevated temperature. 168 nos. of cubic cement mortar blocks (25 mm 25 mm) were prepared with and without steel fibers. The blocks were crushed at different elevated temperatures ranging from 250-650 C after curing of 3...

... cement mortar blocks were heated to 250° C, 450º C and 650º C, respectively at Barnstead Thermolyne Furnace as shown in Fig. 2. For example, after heating to 250° C few cement mortar blocks were crushed by compression testing machine instantly after taking aside from furnace (Fig. 3). Few samples were heated up to the desired temperatures and then they were cooled for 30 minutes and finally, they were crushed using the compression testing ...
