CONSTRUCTION MATERIALS AS THE PROTECTION FROM NEGATIVE INFLUENCE OF ELECTROMAGNETIC RADIATION
Abstract
Technical progress and wide use of electrical energy leads to the use of electromagnetic background that influences human body and environment negatively and requires the development of new materials. The analysis of the existing protective materials against electromagnetic emission is given. The use of construction materials with protective properties is the perspective trend of the in investigation. Three-component system, containing hydraulically active compositions as well as compositions with protective properties has been chosen for the development of new protective materials. Thermodynamical and experimental analysis of the given system has been conducted. Physics and chemical basics to obtain special barium-containing cements with ferromagnetic properties and concretes, produced on the their base have been developed. The analysis of the investigation of physics and mechanical and technical properties of obtained protective composite has been conducted.Keyword: electromagnetic fields, radiation, protective materials, composite materials, construction materials, cement, concrete.
