Application of Similarity Method of Distance Courses Describing the Elements Content in Typical Cement Concrete

Open access

Abstract

The article concerns the use of similarity analysis of distance course in the internal area of cement concrete intended for airfield pavements. Research procedure was presented and the obtained laboratory tests results were discussed. The contents of diversified elements in four zones (cement matrix, contact area between air pores and cement matrix, contact area between fine aggregate and cement matrix and contact area between coarse aggregate and cement matrix) were specified by using scanning electron microscope. Based on the results obtained diagrams similarity of the analysed of areas in the concretes were prepared. The purpose of this article has been the assessment of an opportunity to apply the analysis of similarity of distance courses with respect to cement concrete intended for airfield pavements. The scope of article consisted of two stages. The analysis included cement concretes intended for airfield pavements, in compliance with requirements. The thermal analysis method was used; the selected concrete components were determined by means of quantitative method. The occurrence of crystalline stages was determined using X-ray diffraction method. Internal structure of concrete composite was assessed with the scanning electron microscope.
