Abstract
In recent decades, the number of sudden structural failures of buildings and structures being in operation and under construction has increased in the world. Generally, most of the experts associate these failures with the following reasons: design errors; errors and violations made during construction; and poor maintenance. In our opinion, another reason for the sudden structural failure of buildings and structures and the characteristic of the areas where they occur is the periodic accumulation and alteration of excess negative electric charge and the electric field of the Earth in crust fractures zones, near artificial sources of electricity, DC powered transport, rivers and large water reservoirs. To protect buildings and structures in hazardous excess negative charge areas, a polymer-modified mortar was developed based on carbamide resin cured with chlorine iron, with the addition of a superplasticizer and fly ash from thermal power plants. Theoretical, experimental and practical results of the study are provided.
