Special Issue Information
Dear Colleagues,
As a guest editor of Materials, I am delighted to introduce the upcoming Special Issue of Materials, entitled "Cementitious Materials for Construction: Preparation, Characterization and Applications", as follows:
Cementitious materials are essential components in the construction industry. This category includes cement, concrete, and other materials that play crucial roles in building structures and infrastructure. This Special Issue will focus on the preparation, characterization, and application of cementitious materials. It aims to explore new methods and technologies to improve the performance and durability of cementitious materials and to expand their applications in construction. This Special Issue will feature the latest research results from researchers around the world, covering various aspects, including the preparation of new types of cement, the characterization of their properties, and their application in construction. These research results provide new ideas and methods for the development of cementitious materials, contributing to the sustainable development of the construction industry.

Abstract: Bridges are structures subjected to multiple load types and combination during their service life. The uncertainites linked with the materials behaviour and manufacturing processes lead in many circumstances to the need of testing on real scale of produced elements. This is the case of bridge concrete precast girders, which are often tested in order to predict the ultimate carrying load. The testing procedures are time consuming, expansive in terms of time and money and involve a large amount of logistics and auxiliary equipments and devices. Thus, the testing of scaled-down models in laboratory conditions and extrapolation of the obtained results with respect to the real scale element using the similitude theory principles became in last decade a very common alternative method.
For the manufacturing of a scaled-down model it is necessary to establish certain similitude criteria, in order to fulfill the geometrical and physical conditions between the model and the prototype. In the present paper experimental data regarding the efficiency of the dimensional analysis compu-tation are discussed. The proposed method is conducted by comparing the values at which failure in bending and shear occurs for a 1:10 cementious concrete bridge beam model with respect to the values computed for the prototype beam.
Regarding the obtained results, for the scaled-down tested beam the input force scaling factor foresaw a failure force value P=2368 N and during the testing, the failure occurred at value between P=2350 and 2400 N. Noticing the small difference between the two values, one can confirm that the scaling criteria’s choice was conclusive.
