Ecofriendly bricks elaborated from coal waste of Moroccan Jerrada Mining

Abstract

Abstract. Solid waste generated during mining is one of the major environmental problems associated with this industrial activity. The best solution to overcome the environmental impact of this waste is to find recycling facilities in mass-produced products that can absorb the large quantities of these available byproducts. The present study shows the feasibility of using the coal waste of Moroccan Jerrada mining in the production of ecological brick. The first step consists of consecutive stages of crushing, grinding and heating at 650°C of the coal waste with a small amount of lime in order to promote the reactive products of elaborated binders. The second step of the process consists of mixing treated coal waste with a small amount of marble dust, sand, gravel, and water, then pressed and dried at room temperature to manufacture a laboratory ecofriendly bricks. The mechanical strength and thermal conductivity are investigated.

Long-term Bottom-up Modeling of Renewable Energy Development in Morocco

“…The answer to this question is based on two axes. The first is the absence of this resource on the national territory, while coal has long been extracted from the mines of Jerrada, in the east of the kingdom [36]. The second is the low level of gas infrastructure.…”
