Recycle of Wastes of Clay Brick Industry for Producing Eco-cement
Abstract
This work aims at recycling of the solid wastes of clay brick industry (WCB) in the manufacture of blended cement. The various characteristics of collected samples of the waste were determined. WCB was ground to different surface areas. Different mixes were designed from the WCB and ordinary Portland cement (OPC). After adding the required amount of water for each mix, the pastes were moulded in 5x5x5cm3 mould. The initial and final setting time were measured. The moulded specimens were cured at room temperature for 24hr, then demoulded and cured at water for the required testing time. The compressive strength for the hardened specimens was measured. The kinetic of the reaction was followed by determining free lime and chemically combined water contents. The obtained results were compared with OPC and different types of blended cement already existing in the market. The results clearly illustrate the suitability of WCB for the production of series of different types of blended cement (green products) having great impact on the energy saving moreover decreasing carbon dioxide content released during cement industry .
