“…PCM are used because of properties other than elastic parameters [1][2][3][4][5][6]; however, it is still very useful to know the values of their elastic moduli. Polymers, by which the cement mortar is modified, generally have low values of the elastic modulus, which decreases the elastic modulus of the whole composite.…”

Abstract. The paper focuses on the experimental determination of the dynamic and static compressive modulus of elasticity of selected polymercement mortars and their comparison. The dynamic modulus of elasticity was determined by means of the ultrasonic pulse velocity test and the resonance method. The static compressive modulus of elasticity test was accompanied by a measurement of the material's behaviour using the acoustic emission method, the principle of which is the detection of mechanical dilation waves produced by changes and microscopic faults in the structure of the material. The advantage of the acoustic emission method is the possibility of detecting a crack before it can be found e.g. using a microscope. The outcome of the experiment is a detailed evaluation of the behaviour of polymer-cement mortars made using the values of the elastic modulus and acoustic response of the material during loading.

“…These composites combine a cement matrix with an organic polymer matrix [2]. The composition of PCMs improves some properties, such as workability, flexural strength, adhesion or chemical resistance [3,4]. Cement mortars can be modified by a variety of polymers, e.g.…”

“…To improve the durability of the concrete structure, numerous studies have been carried out in the last several decades [2,3]. Polymer modification is one of the most effective methods to enhance the performance of Portland concrete [4,5]. The polymer modifications to cement concrete were implemented through adding polymer latex, dispersible polymer powder, a water-soluble polymer, or liquid polymer into the cement mortar [6].…”

The concrete roadside structures in Xinjiang, China, such as roadside barriers, bridge rails, and drainage holes, are severely damaged by the coupled effect of seasonal freeze-thaw cycles and deicer salts. To solve the corrosion problems of roadside structures, polymermodified concrete was recommended for the future construction of roadside structures and polymer-modified cementitious coating was suggested for the protection of the current corroded ones. In this study, air-entraining agent and carboxylated styrene-butadiene latex were added for concrete modification and the corresponding performance tests were conducted. In addition, the performances of six types of readily available coating materials, including the acrylic latex modified cementitious coating designed in this study, were tested in freeze-thaw condition with the presence of chloride ions. The results show that 0.013% of the air-entraining agent and 10% of the carboxylated styrene-butadiene latex were appropriate dosage rates for the modification of Portland cement concrete, in terms of the improvement of the freeze-thaw resistance, compressive strength, and chloride impermeability. For the protection of the current corroded roadside structures, the acrylic-modified cementitious coating material demonstrated a good performance and the field monitoring confirmed that the coating is suitable for the protection of the roadside structures in Xinjiang.

“…It is the durability and resistance against corrosion of construction materials that are the characteristics considered in recent years as the chief aim of the research into the process of modifying the existing materials and/or producing new composites of improved properties. Numerous research institutions have been conducting long-term research into the fabrication of new polymer concretes that can be successfully used for protecting structures against the harmful influence of aggressive agents [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”
