“…It was found that CFRP fabric bonded to the tension face of RC beams can signi cantly enhance exural strength, with improvements ranging from 18-20% for a single layer and 40-45% for two layers [29]. Furthermore, incorporating of Nano slag in concrete also found in increasing compressive, exural, and split tensile loads with 17% improvement in compressive behavior [30].…”

This paper presents an extensive experimental investigation into the behavior of beams made of reinforced self-compacting concrete (RSCC). These beams were subjected to strengthening and re-strengthening using various externally bonded sheets made of Carbon Fiber Reinforced Polymer (CFRP) and Glass Fiber Reinforced Polymer (GFRP). The primary aim of this study is to identify an effective wrapping method suitable for RSCC beams that require strengthening and re-strengthening. The experimental program consisted of a control beam and twelve test beams. Among these, six beams (Group-A) were strengthened, and the other six beams (Group-B) were repaired after undergoing 50% preloading using CFRP and GFRP sheets. Three different wrapping configurations were employed: Type 1 involved a single-layer U wrap, Type 2 utilized one layer at the soffit in combination with a single-layer U wrap, and Type 3 entailed a double-layer U wrap with epoxy adhesive. The experimental results revealed that the beam in Group-A, which used the Type 2 wrapping method, demonstrated a remarkable 109% increase in its load-carrying capacity and significantly reduced deflections when compared to the performance of the control beam. Furthermore, the observations from the experiments indicated that wrapping techniques involving CFRP and GFRP sheets outperformed the control specimens. This research provides valuable insights into the effectiveness of different wrapping approaches using CFRP and GFRP sheets in improving the flexural performance of RSCC beams. These findings have the potential to enhance the optimization and practical application of such strengthening and repair methods in RSCC structures.

“…Recently, it is fairly uncommon for concrete to include "supplementary cementitious materials" (SCM) such "fly ash, rice husk ash, GGBS, silica fume (SF), or volcanic ash", all of which are used to partially replace PC and improve the material's qualities [4] . It is generally accepted that about 8 percent of the world's pollutants emitted during production of PC [5] and cement manufacturing is regarded as major contributors to the world's CO 2 emissions due to its rapid expansion in use in recent decades. As a result, the cement sector alone is responsible for the annual release of more than 4 billion tonnes of CO 2 .…”

Concrete has a great ability towards physical strength and durability and is one of the most often utilized building material. The cement companies are finding or seeking an alternative cementitious composite that may reduce environmental impact while increasing concrete’s stability and durability. The researchers have shown keen interest in nanotechnology and industrial by-product which meet the quality standards as well as minimize the harmful emissions produced by the cement industries. This paper mainly focuses on partial alternative to cement in order to improve the properties of concrete, specifically strength and durability. The primary aim of this review paper is to understand the impact on mechanical properties of concrete as well as durability with partial replacement of cement by Nano-titanium dioxide (nano-TiO2) and ground granulated blast furnace slag (GGBS) by analyzing the existing literature based on concrete characteristics.
