Special Issue Information

Dear Colleagues,

The plastics market has grown significantly in recent years. Currently, these materials allow the construction industry to obtain structures that are lighter than standard, easier to install, and eliminate the need for corrosion protection and painting. This reduces labor consumption, and total construction costs are significantly reduced.

In relation to the construction industry, the main advantages of polymers are relatively simple plastics processing, above-average durability, surface smoothness, high corrosion resistance, low weight, and easy connection and assembly.

Polymers have become indispensable components of almost all products used in construction. They play the role of modifying substances or constitute the basic component of a product. With polymers, previously unattainable properties of materials, simplifications in their use, and new technological possibilities have been obtained.

The huge variety of construction chemistry products means that choosing the optimal material for specific applications is not easy. New products are constantly appearing, whose actual properties may not have been fully checked.

The development of re-dispersible polymer technology has revolutionized the production of dry plaster and adhesive mortars, as well as floor underlays. With polymers, mortars obtain the desired properties—high elasticity, adhesion, frost and water resistance, and ability to self-level. Polymers also fulfill the function of flexible expansion joints and mounting gaps and can also be used as a fastening material.

Polymers are also used as additives to modify standard concrete mixtures, masonry, or plastering mortars. In mortars, they play the role of plasticizers, improving workability and replacing the traditional addition of lime. In the case of concrete products with a high proportion of this component, material with much better properties than ordinary concretes can be obtained.

Even though the adoption of innovative polymers in the field of construction chemicals has been demonstrated to be a successful strategy in achieving enhanced performance or even new and unexpected characteristics, several issues are still not completely resolved. The use of polymers or composites that are unconventional in this field creates the need to update or develop new specifications and standards.

The construction industry is an important recipient of polymers. In Western Europe alone, this industry consumes as much as 20% of all produced plastics, and most trading companies supply plastic products for construction. Therefore, plastic production for the construction industry is a dynamically developing market and a field whose significance will grow from year to year.

This Special Issue aims to provide a platform for discussing open issues, challenges, and achievements related to innovative materials proposed for use in construction chemicals.

The synthetic material developed by Dupont in 1963 for solid surfaces has been used since its origin for numerous applications. One of the most popular ones in the last decade is as a finishing layer on façades. The first references that contemplated this use on the outside were the Seeko’o hotel in Bordeaux executed in 2007 and the refurbishment of the 7700 m2 shell of the Hôtel Ivoire congress centre in Abidjan (Ivory Coast) in 2009. In Spain, the first example of the installation of this material is the rehabilitation of the main building of the La Rotonda de la Playa de San Juan urbanisation in Alicante, designed in 1965 by the architect Juan Guardiola Gaya and rehabilitated in 2010 by Miguel Salvador Landmann. Ten years later, our research is focused on the study of the colour ageing of the acrylic resin and natural mineral sheets on each of its façades, with different orientations and exposure to sea and wind. To this end, it has been studied the solar radiation of the surfaces, the wind exposure of their façades and tests with a tele-spectroradiometer has been carried out. The study makes it possible to quantify the differences in colour in all of them and to state that the combination of wind and radiation is the main atmospheric agent causing the degradation.

As a composite material, the damping energy consumption mechanism of fiber reinforced polymer-confined reinforced concrete (FRP-C RC) structure is very complex. In previous dynamic calculation models, the bond-slip effect for steel bars was often ignored, which would lead to a considerable error in the response of the FRP-C RC structures. In this paper, a new numerical model of FRP-C RC columns considering the bond-slip for steel bars is established using a zero-length element and nonlinear beam-column elements in the OpenSees software, and the results of the model are verified by experimental results. Based on the complex damping theory, the loss factor expression and nonlinear damping model of FRP-C RC columns with the bond slip effect are proposed. Finally, the dynamic response of FRP-C RC columns with nonlinear damping under harmonic load is calculated and compared with the results available in literature. The results show that the proposed model considering steel bars’ bond-slip can provide better prediction for dynamic response of FRP-C RC columns and make the future seismic design of FRP-C RC columns safer.
