Description
Summary:The major threat to the environment is the increase of industrial waste mainly the coal. This study attempts to find a scientific solution by recycling the solid waste into an alternative product like the ordinary cement. This latter saves energy reduces harmful gas emissions in general and reduces the cost of producing cement in particular. More importantly, this new material is considered as the main ax of construction of industrial buildings and project construction. For this reason, it is necessary to look for some practical implementations that help to achieve the intended objective of this present study. The experimental part is divided into three phases in which different doses of coal are added in order to measure its effect on the hydration and mobility of cement. Additionally, this experiment permits to find the physic-chemical properties of cement by using the abstract model and the active energy for each sample. This study is inexpensive and has no negative impact on the environment. The present study used the Differential Scanning Calorimeter (DSC). The findings reveal the importance of coal as a pozzalonic element, which contributes not only in moisturizing the cement but also in improving the qualities of cement.
