About the calculus of the prestressed beams using equivalent section method

Abstract

Due to the constant evolution of the consumer market, new building materials appear continuously. One such product is the newly developed composite plaster mortar. The main purpose of the current research is to evaluate the adherence to the support layer of plaster mortars reinforced with polypropylene synthetic fibers. In this experimental study, sets of 2 samples of each recipe were materialized on the substrate of solid bricks. It is intended an analysis of the mechanical characteristics of the material, in order to indicate a specific amount of fibers in the matrix and to recommend some proper application areas.
