Study on the strength characteristics of High strength concrete with Micro steel fibers

Abstract

Abstract. The study of High Strength Concrete (HSC) has become interesting as concrete structures grow taller and larger. The usage of HSC in structures has been increased worldwide and has begun to make an impact in India. Ordinary cementitious materials are weak under tensile loads and fiber reinforced cementitious composites (FRCCs) have been developed to improve this weak point. High Strength concrete containing Alccofine as mineral admixture and reinforced with micro steel fibers were cast and tested to study the mechanical properties. The concrete were designed to have compressive strength of 60 MPa. Mixtures containing 0% and 10% replacement of cement by Alccofine and with 1%, 2% and 3% of micro steel fibers by weight of concrete were prepared. Mixtures incorporating Alccofine with fibers developed marginal increase in strength properties at all curing days when compared to control concrete.

Modified EC2's Shear Strength Equation for No Coarse Aggregate RC Beams

“…High-strength concrete mix is usually made with low w/c, in the range of 0.40 or lower. In order to make concrete with low w/c and acceptable workability, supplementary materials such as superplasticizer and pozzolan are required in the mix [20]. As with conventional, normal-strength concrete, beams of high-strength concrete are still subjected to bending moment and shear [21]- [24].…”

Strong Test Pressure Concrete Use of Asbest Waste

“…(Candra, 2020) As the demand for concrete increases, it is required to have a mix of concrete that is environmentally friendly and has economic value so that it can contribute to reducing increasing global warming. (Gowdham et al, 2017) This study aims to determine how the influence of asbestos waste on the compressive strength to reduce cement. (Cahyo, 2020) role of aggregates in concrete is significant.…”
