“…Waste removal from granite cutting and polishing in Sathya Mangalam, Tamil Nadu, India [7]. According to previous studies, marble powder by-product has been investigated as a replacement material in the manufacturing of concrete, but research on the use of granite powder a byproduct as an additive for concrete has not received as much attention [3,4]. Additionally, the substitution rate for including GP waste in the manufacturing of concrete had not yet been suggested.…”

Population growth and rapid pace of globalization have increased the demand for construction materials. River sand is one of the main materials used to make the fine aggregate for concrete. As a result, finding an alternative to sand has become crucial. Granite debris and M sand are employed in place of river sand in this experiment. In this experiment, granite debris as well as M sand are used in place for river sand. Concrete constructed using granite waste and alccofine was compared to ordinary concrete that had a 0.50 w/c ratio using the M25 mix design. 10% of alum is added to cement, and 0% to 30% of fine aggregate is replaced with granite waste enrich the physical properties by 23%, 9% and 41% in compressive, split tensile and flexural strength. The mechanical and microstructural characteristics are looked at in this investigation. According to the test results, concrete made with 10% alccofine, 15% granite waste, with 85% M sand performs satisfactorily. In addition, super plasticizers are acceptable in the M5 mix compared to the other mixes. The microscopic images show a densely packed cement matrix and the aggregate transition area, which points to strong bonding.

“…Indeed, it is the second most used material on Earth after water [1]. However, the production of concrete is associated with sustainability issues since it is made primarily from cement, aggregate, and water, and each component directly impacts the environment [2]. Global cement production in 2021 was approximately 4.1 billion tonnes [3], while annual concrete consumption is about seven times higher [4].…”

Effect of De-Icing Chemicals on Concrete Scaling: The Role of Storage Water

et al. 2023

This paper deals with the effect of the character of the water used for the water storage of concrete test specimens on the results of tests for resistance to de-icing chemicals. Two experiments were conducted to investigate the effect of the content of free CO2 in water and leaching of calcium hydroxide from concrete on the test results. In the first experiment, the resistance of mortars to water and de-icing chemicals was investigated. It was found that the character of the water storage, i.e., fresh water vs. previously used water, can significantly affect the test results. The second experiment focused on investigating the effect of the content of free CO2 in water on the test results. It was found that the content of free CO2 in the water can statistically significantly influence the test results. In conclusion, the paper shows that the character of the water used for water storage of concrete test specimens and the content of free CO2 in water are essential factors that can significantly affect the results of concrete resistance tests to de-icing chemicals. Further research is needed to understand these influences and their potential use to improve the resistance of concrete.

Electroplating is a widely used technique in the manufacturing of utensils for household and commercial use. This process involves the deposition of a metal coating onto a base material, such as steel or brass, to improve the aesthetics, durability, and corrosion resistance of the utensil. Several studies have investigated the migration of heavy metals from utensils, but there is a lack of research specifically focused on the impact of electroplating on this phenomenon. Therefore, this research article aims to assess the impact of electroplating by analyzing the migration of heavy metals from such utensils. The objective of this research is to assess the impact of electroplating on the migration of heavy metals from utensils. The research also aims to evaluate the impact of coating thickness. Stainless‐steel and brass utensils (Plate, Tumbler, and Bowl) are purchased. The samples are analyzed as per standard test methods based on inductively coupled plasma mass spectrometry (ICP‐MS) techniques. Leaching stimulant is used for extraction process. Testing is performed in an ISO/IEC 17025: 2017 accredited laboratory. The experiments reveal that the electroplating process decreased the migration of lead from the utensils. These findings highlight the need for stricter regulations and standards to ensure the safety of electroplated utensils.
