EFFECTS OF GRP WASTES ON THE PROPERTIES OF SELF-COMPACTING REPAIR MORTARS

Self-compacting repair mortars (scrm) can flow through the narrow sections without vibration requirement. this study is aimed to search the utilization potential of glass reinforced plastic (grp) waste powders occurred during repairing ship and vessel. six mixtures have been prepared with 1%, 2% and 3% grp waste addition by volume into two different matrices including only cement binder as well as ground granulated blast furnace slag (ggbfs) replaced 50% wt. of the cement binder. workability of scrm decreased as a result of grp waste utilization. grp wastes have exhibited different mechanical performance and early age autogenous shrinkage depending on the binder. the increment in grp dosage caused an increase in early age autogenous shrinkage for matrix involving only cement binder while it caused a decrease in autogenous shrinkage value of ggbfs replaced matrix.
