fiberglass concrete vs regular concrete
 

fiberglass concrete vs regular concrete?
i have a 4' by 4' by 1' footing to hold a power generator w=220lbs and stands 8ft of the ground. we need to bolt this unit down (hilt bolts) to the footing and i wanted to know if we use fiver-reinforce concrete would be better than typical concrete mixture. i'm concerned that the bolts might fail in pull out resistance? if we had a horizontal wind force of 400 lb, does anyone have any recommendations or tips? i'm not sure what the strengths are for fiver-reinforce concrete
