The Influence of Nanoclay and Powdered Ceramic on the Mechanical Properties of Mortar

Abstract

The amount of concrete utilized worldwide has lately grown due to rising populations and urbanization. The gas emissions during cement manufacturing and the usage of common resources result in a significant environmental threat. As a result, researchers are attempting to minimize the amount of cement consumed by using waste materials while lowering building costs. This research aims to minimize the amount of cement used in concrete by partially replacing it with ceramic powder waste while also increasing the mechanical qualities of concrete mortar by substituting cement with nanoclay hydrophilic bentonite. Mortar samples were prepared using five different replacement percentages of cement by nanoclay, including 0, 2, 4, 6, and 8%, and two replacement percentages of cement by ceramic powder, including 0% and 20%. Compressive and flexural strength tests were performed on mortar samples for 7, 14, and 28 days of moist curing. The toughness was also measured for all mixes by measuring the area under the load-deflection curve. Also, water absorption and relative densities for all mortar mixes were measured. The results show that replacing cement with 2% nanoclay and 20% ceramic powder increases the flexural strength by 11%. Doi: 10.28991/CEJ-2022-08-07-08 Full Text: PDF

Investigating the Consolidation Behaviour of Cement-Bentonite Barrier Materials Containing PFA and GGBS

“…Despite publishing a study that covered more topics related to CB slurry systems [1], the issue of consolidation behavior was left out. In an effort to mitigate the substantial environmental threat posed by cement, researchers are attempting to reduce the amount of cement used while lowering construction costs by repurposing waste materials [38]. The use of byproducts of the steelmaking industry, such as slag, as a constituent material and partially replacing cement in CB barrier construction is one of the most common and recommended alternatives [39,40].…”

Characterization of Ceramic Tiles Coated with Recycled Waste Glass Particles to Be Used for Cool Roof Applications

“…Among these wastes, as a non-biodegradable one, waste glass (WG) has attracted a considerable attention, only 21% is recycled globally, the rest of the waste is destined to landfill disposal [8]. Hence, the substitution of raw materials by secondary ones such as WG presents an interesting sustainable alternative in the fabrication of construction materials which proved promising results [9][10][11][12][13][14][15][16][17][18][19][20][21]. In this regard, and according to the literature, the construction industry is the main sector testing and using WG in the production of materials, which has been used and tested in different ways; incorporated as a raw material substitution in the fabrication of ceramic-based materials such as tiles and bricks, and in a complete or a partial substitution of clay [14,15].…”
