This paper presents experimental investigations on the mechanical properties of no-slump high-strength concrete (NSHSC), such as the compressive and flexural strength. First, to determine the proper NSHSC mixtures, the compressive and flexural strength of three different water-to-binder ratios (w/b) of specimens with and without polyethylene (PE) fiber was tested at test ages. Then, the effect of hybrid combinations of PE fiber and steel fiber (SF) on the compressive strength, flexural strength, flexural toughness, and flexural energy dissipation capacity was experimentally investigated. Furthermore, the various hybrid fiber-reinforced NSHSCs were evaluated, and their synergy was calculated, after deriving the benefits from each of the individual fibers to exhibit a synergetic response. The test results indicate that a w/b of 16.8% with or without fibers had lower strength and flexural strength (toughness) than those of other mixtures (w/b of 16.4% and 17.2%). Specimens with a hybrid of SF and short PE fibers exhibited a higher compressive and flexural strength, flexural toughness, energy dissipation capacity, and fiber synergy in all considered instances.

Bond Characteristics

The purpose of this study is to investigate the bond characteristics between ECC(Engineered Cementitious Composites) and GFRP(Glass Fiber Reinforced Polymers) rebars. An experimental study was carried out to investigate the bond-slip properties of the steel and GFRP rebars in ECC which was reinforced with Polyvinyl Alcohol(PVA) fibers. A total of 8 beam specimens, which was designed according to the RILEM guidelines, was tested according to the RILEM guideline. The main objective was evaluating the load versus displacement and load versus slip behavior and the bond strength regarding the influence of the following parameters : concrete type(Normal concrete and fiber reinforced concrete) and bar diameter and type. From the test results, concrete and ECC specimen presented similar behavior for steel reinforced specimen. However, GFRPO reinforced specimen show different behavior with that. Comparative study for test and equations of MC90 was carried out and code provision predicted the bond characteristics conservatively.

Abstract The durability characteristics of Engineered Cementitious Composites (ECC) with various fibers such as polypropylene and glass were investigated in view of developing composites with high resistance to cracking. ECC offer large potential for durable civil infrastructure due to their high tensile strain capacity and controlled micro-crack width. In this study, fibre volume fractions (0.5%, 1%, 1.5%, and 2%) of both polypropylene and glass fibers varied and durability measures such as a rapid chloride penetration test, sorptivity, water absorption, acid attack, and sulphate attack were measured. Increasing the fiber content up to 1.5% improved the durability properties of ECC. The test results indicate that the glass fiber-reinforced Engineered Cementitious Composites have better durability characteristics than polypropylene fiber-reinforced ECC.
