摘要：This paper focuses on the experimental investigation carried out on modified polyester (recron3s) fibrereinforced concrete with fibre taken in weight fraction of 0.25%, 0.5%, 0.75%, 1% and 1.25% to the weight of cementin mix, which was prepared using normal hand mixing with general approved procedure. All raw constituent as cement,aggregates and water are tested and examined for appropriate concrete mix. The crack due to drying shrinkage wasstudied for concrete by comparing specimen with different proportions of polyester fibre. An experimental arrangementis prepared with a panel, binding wire, smooth plastic film etc and exposing specimen to extreme condition to gainenough crack width that can be evaluated. The cracking is determined by comparing the cracking of test panels exposedsimultaneously to a set of severe conditions designed to cause cracking, this is an experimental test to determinecracking only due to drying shrinkage. The net result of all these impart that fibre composite most amazing effect incontrolling dry-shrinkage crack under extreme condition which is unheard of in ordinary concrete. Addition of Recronfibres Contributed towards the secondary reinforcement at micro level with bridging action which resulted incontrolling the formation of micro-cracks.
