In order to mitigate environmental impacts generated by both the ceramic industry and civil construction, this paper aims to analyze the technical feasibility of using ceramic material waste as an alternative material for the production of lining mortars. Thus, the methodology of this work was developed from the production of coating mortars with replacement of the natural fine aggregate by red ceramic waste in the proportions of 0%, 20%, 50% and 100% of fine aggregate, evaluating the performance in the fresh and hardened state of the mortars. In the fresh state, the substitutions reduced the spread and the mass density of the mortars. In the hardened state, the substitutions of 50% and 100% positively influenced both the compressive strength and flexural tensile strength, increasing significantly compared to the reference mortars.

The number of publications containing experimental data on shrinkage phenomenon of n building elements is high. In the search and selection of bibliographic material, this high number makes the work of researchers more complex and extensive. Thus, a bibliographic review, between the years 2013 and 2018, was carried out, with the topic drying shrinkage and plastic shrinkage in coating mortars. Using the procedures of the MethodiOrdinatio method, the current position of research on this topic was evaluated. Despite the growing number of researches, the disparity in the amount of research between the two types of shrinkage is notable. Most studies are about shrinkage by drying. In addition, studies related to plastic shrinkage were less relevant in the scientific field. These studies appear only in 12th place in the ranking of relevance, does not show the real importance of this type of shrinkage in the characteristics of the plastic and hardened state of the material. Thus, it is very important to fill the gaps in existing knowledge and develop tests capable of evaluating the shrinkage of the material in the plastic state. [ABSTRACT FROM AUTHOR]

The evaluation of the thermal performance of walls of a building is of paramount importance since the thermal comfort conditions reflect directly on the quality of housing of users. Thus, the objective of this paper is to analyze how the thermal radiation theme was approached and which methods were used by previous research to evaluate the thermal radiation in mortars in the civil construction segment. Thus, a systematic review literature of the last 10 years was carried out using the MethodiOrdinatio methodology. Based on the study of the articles it was concluded that the study of thermal radiation in coating mortar had significant growth in the year 2017. Thermal radiation is generally neglected in thermal performance calculations and is not considered in many countries standards. The infrared thermography camera method as a tool for thermal performance analysis has been widely used in qualitative analysis of building elements. However, for quantitative studies, infrared thermography assays are still incipient. [ABSTRACT FROM AUTHOR]
