摘要: Abstract In the present study, split tensile strength of slag based geopolymer composite reinforced with steel fibers has been designed by Taguchi method. this ceramic matrix composite, furnace metallurgical rockwool acts as an aluminosilicate source. Four main parameters including water curing regime, sodium hydroxide concentration, alkali activator to cement weight ratio and percent, each at three different levels, were considered for examination. A total number 9 experiments performed according L9 array which was proposed The obtained results evaluated analysis variance (ANOVA) method determine optimum level factor. ANOVA revealed that specimen regime 14 days, concentration 14 M, Alkali 0.24 5 wt% potential highest (8.87±1.71 MPa) in procedure. Based on achievements, it is possible produce high fibers. Also, shown could be suitably
