Fiber-reinforced self-consolidating concrete (FRSCC) is a new type of concrete mix that can mitigate two opposing weaknesses: poor workability in fiber-reinforced concrete and cracking resistance in plain concrete. This study focused on cracking of FRSCC due to restrained drying shrinkage, one of the most common causes of cracking.

recycled PP fibre produced by the hot drawing process were presented and compared with those of 100 % virgin PP fibre and the PP fibre with mixture of virgin (50 %) and recycled (50 %). Finally, the mechanism about how the hot drawing process improves the mechanical properties of the plastic fibres was studied through testing crystalline structure
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 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.
Recycled PP fibres were produced through a melt spinning and hot drawing process. • Mechanical properties of recycled PP fibre were studied. • Post-cracking behaviour of fibre reinforced concrete was assessed by CMOD and RDPT.
The LCA results showed that industrial 100% recycled PP fibre offers significant important environmental benefits over virgin PP fibre and SRM. Specifically, the industrial recycled PP fibre can save 93% of CO₂ equivalent, 97% of PO₄ equivalent, 99% of water and 91% of oil equivalent, compared to the SRM.

3 Introduction INEOS O&P's polypropylene is a strong, lightweight thermoplastic that offers outstanding toughness, rigidity, and resistance to thermal deformation. Fabricators and designers value these characteristics and have come
Micro fibers have a diameter that is less than 0.3 mm. Micro fibers are either monofilament or fibrillated. Micro fibers should be used for plastic shrinkage control (cracking that can occur in the first 24 hours of concrete cure), impact protection, and reduction of explosive spalling during a fire.
Fibre-reinforced concretes, commonly referred to by the term #smartFiber, are prepared using discrete fibre reinforcement in addition to traditional ingredients used in cement mixes. Fibre-reinforced concretes known as #smartFiber, with respect to traditional mixes are characterised, depending on the type and dosage of the fibre used, by excellent resistance to cracking during the plastic ...
Nov 15, 2018 · Most rPET is obtained through mechanical recycling, as it is the cheapest of the two processes and requires no chemicals other than the detergents needed to clean the input materials. However, “through this process, the fibre can lose its strength and thus needs to be mixed with virgin fibre,” notes the Swiss Federal Office for the Environment.
