“…Deformation vibrations of C-H bonds are present at wavenumbers 777-796 cm −1 . Peaks observed at a wavenumber of 694 cm −1 are related to bending vibration of O-Si-O [31], while those around 460 cm −1 are associated with torsional motion in organic molecules [32]. Figure 1b presents the results of thermogravimetric/differential thermal analysis (TG/DTA) of vegeblock No.…”

Waste cooking oil poses a serious threat to human health and the environment, both in households and in larger communities. One of the applications of waste cooking oil is composite materials called vegeblocks, which can be used for construction purposes. These composites are formed by the process of polymerisation, esterification and polyesterification. The resulting materials exhibit mechanical strength in line with the requirements for paving blocks. Composite materials that have been annealed for a minimum of 20 h at 200 °C or higher have the highest tensile strength (above 5 MPa). In contrast, composites with the highest flexural strength were obtained after processing at 210 °C for 16 h. The Saxa 2 variety showed the greatest inhibition of storage root growth (almost 43% compared to the control sample), as well as stimulation of root and leaf blade growth (by a maximum of 61.5% and 53.5%, respectively, compared to the control sample). The composite obtained from the maximum process parameters resulted in significant growth of both the root and the green part of both radish varieties by up to 35%. The study showed that the presence of vegeblocks in the plants causes stress conditions, resulting in increased peroxidase content compared to the control sample. The presence of the oil composite in the soil did not increase the amount of catalase in the radish, and even a reduction was observed compared to the control sample.

“…Hence, calcium hydroxide substance is ordinarily diminished due to the auxiliary hydration response caused by RHA particles [9]. results in all aspects of the construction field due to its good microstructure and excellent volcanic ash activity [10,11]. The execution of RHA ordinarily depends on the strategy of pretreatment and degree of warm treatment [12].…”

Within the past few decades, fabricating 1 ton of standard cement (OPC) will transmit about 1 ton of carbon dioxide. With the increase of demand for cement production, the global carbon dioxide emission has increased by 8%, resulting in huge ecological problems. The continuous development of construction and cement industry has aggravated air pollution and human health damage. Therefore, environmentalists and governments at home and abroad call for the use of other environmentally friendly Supplementary Cementitious Materials to strictly control the carbon dioxide emission rate. Rice husk, as the biggest by-product in rice generation, has been ignored for a long time, and the way of successful utilization of rice husk has not been found. Subsequently, renewable cement based on rice husk cinder (RHA) can be made. This paper analyzes the application prospect of RHA in ordinary silicate concrete and the influence of RHA preparation conditions on RHA, hoping to provide reference for the application of RHA in ordinary silicate concrete.

The mining industry produces a considerable amount of stone waste and tailings, posing an ecological danger. This industrial waste is often disposed of via landfill, which leads to soil degradation and water and air pollution while obtaining valuable land. It can be recycled via a variety of methods, including the promising geopolymerization approach, which converts waste into value. This research investigates recent advancements in the production of geopolymer composites derived from industrial waste and mine tailings as a potential sustainable construction material. This research also provides in-depth analyses of the features and behaviours of mine tailings mixtures utilized in geopolymer production, such as their durability, microstructure, thermal and leaching capabilities. This study also reveals an information gap that must be addressed to progress mine tailings composites for cementitious materials.
