Abstract: The electrostatic precipitator cement kiln dust waste (EPCKD) which is a byproduct coming from the different cement factories. This waste is a very dangerous material on the environment and also on the human health, where it causes air, water and soil pollution in the area surrounding the cement factories in Egypt and all over the world. So, the main objective of this review is to show the very huge amounts of the EPCKD waste accumulated behind the kiln filters and its negative effect on the environment. Also, the review illustrates the various diseases from which the inhabitants are suffering. Finally, the review shows as possible the different fields of applications in which this very dangerous material was utilized successfully, particularly in the field of building materials.

Abstract: It is known that volcanic eruptions released vast quantities of gases, vapors and significant amount of lava. Such volcanic release defuses intense condition beneath the crust, reduces the pressure in the deep layers. In such circumstances, the crust under its own weight and the weight of erupted lava gives deflection deformation, aiming to restore the disturbed balance between the acting forces and reactions. Based on the investigations of stress-deformed state of volcanic areas can be possible to predict the fracture in the regional lava rocks under the weight of the structure itself. The mathematical solution of the problem is examined by the example of the Aragats volcanic massif in Republic of Armenia using two possible models: Model 1, Model 2. The gravitational field of the region consists of a set relative minimums and maximums; the deepest minimum of gravity is characterized by apical zone. At the same time the central part of the massive of is contoured by large gravity gradient zones. Our comparison has shown that, according to the first approximation, there is a planned coincidence of calculated regional fractured lava zones with large gravity gradient around Mount Aragats. It is advisable to more efficiently distribute the volumes of field work in establishing deep regional fractured zones, within which congestion (and movement) of groundwater is possible.
