The Impact of castoff aggregate on the fresh and mechanical behaviour of high-range water reducer administered self-compacting concrete

Crack development is common occurrence in concrete structural element. By the cracks, which permits the H2O and varies form of chemicals inside the concrete elements and lessen their durability characteristics, properties of strength and which make the rust on rebar when its contact with H2O, Carbon-di-oxide(CO2) including other chemicals. In the concrete structures to repair it needs usual maintenance and particular unique method of treatment but it will not be cost effective. To rectify the issue the mechanism of self-healing is induced in concrete element which assists by generating crystallization of CaCO3 to repair the cracks which helps to clog the micro nano-cracks and endopores. The literatures studies were carried and the bacteria were selected based on the condition of survive in the pH greater than 10. The mix design of M30 concrete grade was designed for the work. The Culturing or Diluting of Calcite Depositing Bacillus Subtilis Bacteria was carried. The casted specimens are to determine the mechanical characteristics of concrete without and with bacteria for different cell concentrations for the comparison. After the curing period, the concrete with bacteria improves the structural properties which were found by the strength characteristics experiments on different cell concentration specimens in comparison with normal concrete. The crack closure and micro structural analysis were carried out by using Ultrasonic pulse velocity test and SEM analysis.

An investigation of biopolymers in corrosion resistance under industrial exposure condition

et al. 2024

India, a developed country with a bounty of resources, has produced a large number of biopolymers that were employed in historical construction. If these biopolymers are proven through research to have positive aspects, it would eventually result in the development of environmentally friendly, cost-effective, and long-lastingstructures. Although many of the efficient inhibitors, like chromate and arsenate, are exceedingly poisonous, the price of inorganic inhibitors is generally inexpensive. As neem and turmeric extracts are readily available and may be obtained year-round in concrete, they should be further investigated as corrosion inhibitors in various ratios and combination. This experimental investigation can be used to provide a corrosion inhibitor that is affordable, non-toxic, eco-friendly, and user-friendly.The application of biopolymer in concrete has been supported by the results of the feasibility study, which additionally showed promising result for aexcellent corrosion inhibitor from the phytochemical analysis and results for compressive strength.

An Experimental Investigation of Glass Cullet as a Material to Partially Replace Fine Aggregate in Concrete

et al. 2024

The concrete industry is a major user of natural resources, which puts its sustainability in jeopardy. Considering this, this work explores how to partially replace fine aggregates in concrete production with waste glass cullets, thus addressing economic problems. With an emphasis on the M-20 mix, several weight percentages of leftover glass cullet—0%, 10%, 20%, and 30%—were used in place of fine aggregates. To assess the effectiveness of the replacement, these outcomes were then compared to those of traditional concrete. The results of this investigation validate the feasibility ofadding leftover glass cullet to replace some of the fine aggregates, up to 30% of the total weight, in the 0-1.18 mm particle size range. This not only highlights the possibility for resource optimization and waste minimization in construction procedures, but it also provides a workable answer to the sustainability issues facing the concrete sector. Stakeholders can transition to a more economically and environmentally viable paradigm in the manufacture of concrete by adopting such creative ideas. Furthermore, this study adds to the expanding corpus of studies supporting environmentally friendly building methods. It opens the door for more widespread adoption of environmentally friendly practices and promotes a more robust and environmentally friendly built environment by showcasing the viability and advantages of using waste materials in the concrete production process.
