An experimental study on mechanical and durable properties of self-curing concrete by using Ferro silica slag aggregate

Abstract

Construction industry concrete used heavily. The building industry relies heavily on coarse aggregate (C.A.). Due to the lack of C.A., artificial aggregate known as Ferro silica slag (F.S.S.) is the predominant alternative material. The Use of F.S.S. increases concrete strength and lowers construction costs. The strength of concrete is determined by how long it is allowed to cure. Because of improper curing, the hydration of cement problem can be solved by employing a self-curing mechanism. It’s possible to use paraffin wax Light and Heavy in Concrete have a variety of beneficial effects on S.C.C.’s fresh and hardened concrete qualities. The immersing curing agent is a material that retains Water and reduces evaporation; the self-curing admixture incorporates concrete after the standard setting of concrete on account of increased water retention capacity and compares to internally cured concrete. It gives inside assuaging, known explicitly as “self-curing concrete,” in short, less or no external curing is required in another way if outside mitigating may cause better warmth of hydration. Light molecular weight and high molecular weight are two examples of self-curing liquids that can boost the strength and serviceability of concrete. In this investigation, the percentage of paraffin wax in M25 grade concrete was altered from 0%, 0.1%, 0.5%, and 1.0% and compared to internally cured concrete(I). The replacement of coarse aggregate with the optimum amount of F.S.S. Paraffin is then added to concrete in a liquid form, resulting in varied dosages. Based on the literature, the optimum percentage of F.S.S. 40% with paraffin wax light and heavy 1.0% improvement of compression and flexure strength of concrete. Ultrasonic pulse velocity (U.P.V.) and Rapid chloride penetration tests (RCPT) were used to determine dense microstructure and enhanced durability of concrete.

Study on Replacement of Fine Aggregate with Light Weighted Super Absorbent Material in Internal Curing Concrete: A Review

“…concrete are more similar to those of water-cured specimens, whereas internally cured specimens have a lower value. [1] With axial compression, SAPC's residual strength and compressive shear strength both rise linearly. Nonetheless, the integrated stress friction coefficient and compressive shear strength drop with increasing SAP content.…”

“…Kumar, K. Sundeep and PV Subba Reddy (2022) [1] the process potential, mechanical features, and durability of S.C.C. assessment were the focus of this study.…”

“…In comparison with internally cured concrete, SBF 1.0% and SBM 1.0% mixtures obtained maximal compressive values of all ages. [1] As the amount of internal curing water in SAPC increases, so does its compressive tensile strength and fracture toughness. It must be pointed out that the rate at which concrete's compressive strength decreases is higher than the rate at which its tensile strength decreases when the total water-cement ratio rises.…”

Study on Replacement of Fine Aggregate with Light Weighted Super Absorbent Material in Internal Curing Concrete

“…Internal curing is "the process of pre-wetting a lightweight aggregate using a reservoir that will easily remove water needed for hydration or restore water lost through evaporation or self-drying," according to the American Concrete Institute. 1) This investigation aims at exploring the influence of internal curing on the properties of high performance concrete. This is followed by a desire to transfer internal curing from research and lab to field experience.…”

Implementation of industrial waste Ferro Silica Slag in conventional concrete-A sustainable approach

“…According to Mindess et al, 2003 [28], the micro crack's width is not uniform. The micro crack width decreased on SCC usage of FSS aggregates with curing compounds Sundeep et al, 2022 [29]. For each sample at different ages, the microcrack width was measured in the concrete core three times.…”
