with polypropylene than polar media such as ethanol and acetone. Some reduction in tensile strength and an increase in ˛exibility and elongation-to-break in tension can be expected, depending on the nature and amount of the organic medium absorbed. HMC PP resins have excellent resistance to environmental stress-cracking. When

Use of macro plastic fibres in concrete: A review

Hsie et al. tested the flexural strength of macro PP fibre reinforced concrete. The PP fibre had diameter of 1 mm, length of 60 mm, tensile strength of 320 MPa and Young’s modulus of 5.88 GPa. As can be seen in Fig. 4, the plain concrete showed a brittle failure. The flexural strength reached the maximum at a deflection of around 0.05 mm ...

Influences of Environmental Conditions on the Cracking

Cracking tendency is one of the important performances of dry-mixed plastering mortar (DMPM). Environmental condition is a key factor to affect the cracking tendency of DMPM. For the purpose of evaluating the cracking resistance of DMPM and revealing the influence of environmental conditions on the cracking tendency of DMPM, a series of experiments were performed on restriction-induced ...

Environmental stress cracking: A review - Robeson - 2013

Environmental stress failure of polymers (specifically glassy thermoplastics) is a major failure mode in application end use. The environmental stress failure discussion will primarily be limited to non‐reactive environments. Crystalline polymers and even lightly crosslinked polymers can exhibit similar failure to glassy polymers but often require a much higher external applied stress.

Research

The inadequacy of polypropylene (PP) fibre application in fibre reinforced concrete (FRC) is the low performance on bonding characteristic with cement matrix compared to other types of fibres. The poor bonding of PP fibre is due to its low surface energy traceable to its hydropobic behavior and smoothness and its low roughness.

Influences of fiber content on properties of self‐compacting

This paper deals with the mix design and mechanical properties of self‐compacting steel fiber reinforced concrete (SFRC). By using superplasticizers and mineral admixtures such as slag and fly ash, three SFRC of different fiber contents (0.5, 1.0 and 1.5%) and one plain concrete with high fluidity (slump ≈250mm) have successfully been developed without bleeding or segregation.

Properties of Polypropylene Fibres

Because of its low specific gravity, polypropylene yields the greatest volume of fibre for a given weight. This high yield means that polypropylene fibre provides good bulk and cover, while being lighter in weight. Polypropylene is the lightest of all fibres and is lighter than water. It is 34% lighter than polyester and 20% lighter than nylon.
