This article proposes hybrid fiber-reinforced concrete (HFRC) mixed with polyvinyl alcohol fiber (PVA) and polypropylene steel (FST) as a wall construction material to improve the bearing capacity durability of frozen shaft lining structures in deep alluvium. According stress characteristics engineering environment lining, strength, impermeability, freeze–thaw damage, corrosion resistance are t...

This paper presents a recycled aggregate concrete (RAC) mix that has been modified by adding treated recycled concrete aggregate (RCA) and various types of fiber-reinforced systems. The effectiveness of these modifications in terms of energy absorption and impact resistance was evaluated and compared with that of the corresponding regular concrete, as well as with unmodified RAC specimens. Resu...

Pervious concrete (also called porous concrete) is one of the most promising sustainable and green building materials today. This study examined high-strength pervious ordinary-strength reinforced with steel fiber or glass fiber. A total fifteen mixtures normal- concretes were used. The goal that 28-day compressive strength be above 42 MPa porosity as close to 15% possible achieve technical spe...

Abstract Concrete is an indisputable material for the construction of various types of structures in the modern advancement of civil infrastructures. Concrete is strong in compression but weak in tension and shear. To eliminate those problems, the introduction of fiber was brought in as an alternative to developing concrete in view of enhancing its tensile and shears strength as well as improvi...

The influence of steel fiber and polypropylene mixed on compressive strength high performance concrete (HPC) was studied. content (0.5%, 1.0%, 1.5%, 2.0%) (volume fraction, the same below), (0.05%, 0.1%, 0.15%, 0.2%) length (5mm, 6.5mm, 12mm, 18mm) were studied by L 16 (4 5 ) orthogonal test for 28d ages, range analysis variance results are carried out, prediction model hybrid reinforced establ...

Concrete is the most used construction material in world; however, its deficiency shrinkage and low tensile resistance undeniable. Used as secondary reinforcement, fibers can modify concrete properties various ways. Carbon-fiber-reinforced highly suitable to maintain longevity of infrastructure where corrosion steel shorten useful service life structure while polypropylene mostly improve concre...

the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...
