Effects of Polypropylene Fibre Length on Fresh Properties of Concrete
The provision of fibre reinforcement in concrete is a commonly used technique in modern concrete technology.Among various types of fibres,polypropylene(PP)fibre is widely used due to its advantages of low cost,good corrosion resistance and substantial improvements in mechanical properties,crack resistance and fire resistance.However,the systematic research on the effects of PP fibre,especially the PP fibre length on the fresh properties of concrete is still lacking.In this study,a series of PP fibre concrete with various W/C ratios,PP FIBRE lengths were produced to carry out slump-flow test,J-ring test,V-funnel test and sieve segregation test.The test results showed that,apart from W/C ratio,PP fibre length also had significant effects on the workability,gap passing ability,flowability and cohesiveness of concrete.
