The present paper offers a meso-scale numerical model to investigate the effects of random distribution of aggregate particles and steel fibers on the elastic modulus of Steel Fiber Reinforced Concrete (SFRC). Meso-scale model distinctively models coarse aggregate, cementitious mortar, and Interfacial Transition Zone (ITZ) between aggregate, mortar, and steel fibers with their respective materi...

PURPOSE The aim of this in-vitro investigation was to describe the effect of reinforcement with different fibers on impact strength of heat polymerized polymethyl methacrylate (PMMA) denture base resin and to analyze the effect of surface treatment of the fibers on the impact strength. MATERIALS AND METHODS The specimens were fabricated from the dies formed as per standard ASTM D4812. 2% by w...

Polypropylene / polystyrene blends containing montmorillonite (MMT) were prepared using a twin screw extruder followed by fiber spinning. The melt intercalation of PP and PS alloys was carried out in the presence of a compatibilizer such as maleic anhydride-g-polypropylene (MPP). The crystallization morphology, thermal behaviors and mechanical properties of polypropylene/polystyrene (PP/PS) nan...

OBJECTIVE To compare the effect of storage on expressed colostrum kept at room and refrigeration temperature in 2 different types of containers (steel and plastic) at different time intervals (0 hours to 7 hours). DESIGN Prospective immunological study. SETTING Maternity ward. METHODS Colostrum was collected from 60 healthy lactating mothers and tested for total and differential cell coun...

The drawbacks are that the concrete has been improved by using hybrid fibre in concrete. By hybridization benefits from two different fibres utilized a single mixture. hybrids studied basalt-polypropylene fibre, polypropylene-steel steel-coconut polypropylene-e-waste polypropylene-polyvinyl Alcohol and steel-glass- polypropylene fibre. properties compressive strength, tensile flexural limited c...

the total coal and lignite consumption of the thermic power plants in turkey is approximately 55 million tons and nearly 15 million tons of fly ash is produced. the remarkable increase in the production of fly ash and its disposal in an environmentally friendly manner is increasingly becoming a matter of global concern. studies for the utilization of fly ash in turkey are necessary to reduce en...

This study presents an application of artificial neural networks (ANN) for the prediction of repeated creep test results for polypropylene (PP) modified asphalt mixtures. Polypropylene fibers are used to modify the bituminous binder in order to improve the physical and mechanical properties of the resulting asphaltic mixture. Marshall specimens, fabricated with M-03 type polypropylene fibers at...

in this research, water and steam absorption behavior and also effect of maleic anhydride polypropylene (mapp) on these behaviors in wood fiber-polypropylene composite were compared. for this purpose, the composites were manufactured from 60% fibers and 40% polypropylene in presence and absence of ma. the oven dried samples with dimensions of 2.5×2.5×1 cm were immersed in distilled water and ex...
