Fresh and hardened properties of self consolidating fiber reinforced concrete

fresh and hardened properties of self consolidating fiber reinforced concrete-70

Two classes of SCLC were produced containing either coarse or coarse and fine lightweight aggregates.

ASCE Library will undergo scheduled maintenance on Tuesday, June 6th, between am- pm (EDT).Moreover, it was revealed that increasing the content of PP fiber reduces the effect of recycled steel fiber in improvement of the flexural strength. Although carefully collected, accuracy cannot be guaranteed. Differing provisions from the publisher's actual policy or licence agreement may be applicable.This paper presents the fresh and hardened properties of self-compacting concrete (SCC) containing plastic bag waste fibers (PBWF).The major impact of the introduction of self-compacting concrete (SCC) is connected to the production process.The productivity is drastically improved through the elimination of vibration compaction and process reorganization.The impact performance was also improved due to the use of fibers.

This paper presents the results of a comprehensive experimental characterization on the fresh and hardened state of self-compacting lightweight concrete (SCLC) reinforced with steel fibers.

Fibers were prepared by recycling waste material such as, plastic bag.

Fourteen mixtures of SCC with 0.40 of water/cement ratio were studied, twelve SCC mixtures with plastic bag waste fiber (WFSCC) by varying the length of fibers (2, 4 and 6 cm) with different levels of incorporation (1, 3, 5 and 7 kg/m3) and two other mixtures, one with 1 kg/m3 of polypropylene fibers (PFSCC) and another without fiber as reference (RSCC).

Slump flow, inverted slump flow and “V” funnel tests were performed to characterize the self-compacting behavior of the concretes.

The mechanical behavior was evaluated by means of compression, tensile and flexural tests.

The improvement varies from 4% to 74%, it depends on the amount of fibers, and it is not affected by the length of PBWF.
