Production Load–bearing Concrete Masonry Units by Using Recycled Waste Crushed Clay Bricks; A Review

Abstract

There are serious environmental problems in all countries of the world, due to the waste material such as crushed clay bricks (CCB) and in huge quantities resulting from the demolition of buildings. In order to reduce the effects of this problem as well as to preserve natural resources, it is possible to work on recycling (CCB) and to use it in the manufacture of environmentally friendly loaded building units by replacing percentages in coarse aggregate by volume. It can be used as a powder and replacing of percentages in cement by weight and study the effect on the physical and mechanical properties of the concrete and the masonry unit. Evaluation of its performance through workability, dry density, compressive strength, thermal conductivity, and absorption test, and the experimental results obtained confirmed the possibility of using the recycling of clay bricks waste as aggregates instead of natural aggregates and reducing the weight, as well as recycling clay bricks waste and using it as a powder. It contains suitable pozzolanic that can be used as a supplementary cement material that reduces the cement content in concrete used to produce load-bearing units.

Construction and Application of Coral Reef Resources Garden Engineering Based on Ecological Value Assessment

“…The choice of evaluation method is a key to the evaluation of ecosystem value. Abbas (2022) divided the evaluation methods of ecosystem value into four categories: material quality evaluation method, value evaluation method, emergy analysis method, and ecological model method. Ai et al (2022) divided the evaluation methods into four categories.…”

“…First being, it helps to evaluate the total amount of natural resource assets in a country or a region, so as to judge the natural resources of a country or region (Ramadhan & Nuryanti, 2021). The increase or decrease in total resource assets serves as an important basis for assessing total natural capital (Abbas, 2022). Second, through the evolution and deepening of the natural resource balance sheet from a physical scale to a value scale, it is helpful to deduct the corresponding reduction in the value of natural resource assets from the economic accounting results and to achieve (statistical department) true "green accounting" (Martínez-Rendis et al, 2020).…”

Effect of Carbon Fibers on some Properties of Pervious Concrete Containing Brick Waste

“…These recyclables help to reduce the issue of excessive loads of concrete; the volumetric proportions of coarse aggregate can be replaced with recycled clay brick aggregate, which can be used as coarse aggregate. [12]. Many researchers have studied replacement cement with Metakaolin in pervious concrete.…”

Impact of Glass Waste on the Flexural, Compressive, and Direct Tension Bonding Strengths of Masonry Bricks

“…For these reasons, waste materials must be collected, reused, or recycled [Zeng et al, 2020]. Waste materials include different types and can be reused for different functions, such as eggshells as cement replacement , plastic waste as fibre in concrete [Abdulhameed et al, 2022], scraped tire as recycled rubber aggregate , waste crashed clay brick [Abaas et al, 2022]. One of these materials is waste glass; its waste increase day after day is glass since it has so many functions in human life [Papadogeorgos and Schure, 2019].…”
