“…In the top 10 of the most productive institutes, unfortunately no institute was found in South America, showing the poor research carried out in this part of the continent. It should be noted that the institutes from Germany and in second place those from India are the ones with the highest global references (TGCS), evidencing that India is definitely the developing country that is intensifying the production of research in cement substitutes as a means to achieve the social and economic development of the country [19], [20].…”

The substitution of cements has been an area of research development by the vast majority of countries, which seek new alternatives that strengthen the cement industry and mitigate the environmental impact. The study of this area has marked a growing trend whose objective seeks to reduce emissions of polluting gases into the atmosphere. In order to help determine the investigative direction regarding cement substitutes, a bibliometric analysis was carried out on this subject in the period between 2013 and 2018. The meta-search engine Web Of Science (WoS) was used, it was interpreted by half of the HistCite software. We analyzed 1000 documents obtained which showed an increasing tendency in the publication of studies related to this area. It was determined that countries such as China, France and US are the ones with the highest number of scientific publications. In this research, 3,190 authors deepened this area of interest, with Construction and Building Materials, the Journal of Cleaner Production and Cement and Concrete Research, the most published journals and the Malaviya National Institute of Technology, Southeast University and the University of Cergy-Pontoise. institutions with the most publications. Finally, the word "cemento" is the most used keyword of 2191 researched, followed by the word concrete. Giving information this work seeks to strengthen future research to contribute to technological growth and research on the subject of cement substitutes.

“…The use of recycled glass has wider implications, it is an environmentally friendly material, an affordable constructive solution and is technically feasible, even in countries where manpower has limited technical skills [25]. Previous research by the authors has focused on clarifying the feasibility of such materials on the basis of its chemical, mineralogical, physical, thermal and mechanical properties, and former studies claim that a percentage of recycled glass between 25% and 50% results in mortars with a lower thermal conductivity and higher density that, at the same time, have mechanical capacities comparable to mortars with natural aggregates [26,27].…”

“…In previous works, the potential viability of the materials being studied has been clarified [26,27,45], starting from the evaluation of the chemical, mineralogical, physical, thermal and mechanical characteristics, as well as the correlation with thermal conductivity coefficients [46]. The thermal conductivity results have confirmed that the doses with 25% and 50% of glass aggregate have thermal conductivity coefficients that are noticeably lower than those of the reference material, and also higher densities, maintaining a sufficient mechanical capacity compared with natural aggregate mortars (Table 1).…”

Including recycled waste material in cement mixes, as substitutes for natural aggregates, has resulted in diverse research projects, normally focused on mechanical capacities. In the case of recycled glass as an aggregate, this provides a noticeable improvement in thermal properties, depending on its dosage. This idea raises possible construction solutions that reduce the environmental impact and improves thermal behavior. For this research, an extended building typology that is susceptible to experiencing the risk of energy poverty has been chosen. The typology is typical for social housing, built using mortar blocks with crushed glass. First, the basic thermophysical properties of the mortars were determined by laboratory tests; after that, the dynamic thermal properties of representative constructive solutions using these mortars were simulated in seven representative climate zones in Chile. An analysis methodology based on periodic thermal transmittance, adaptive comfort levels and energy demand was run for the 21 proposed models. In addition, the results show that thermal comfort hours increases significantly in thermal zones 1, 2, 3 and 6; from 23 h up to 199 h during a year. It is in these zones where the distance with respect to the neutral temperature of the m50 solution reduces that of the m25 solution by half; i.e., in zone 1, from −429 °C with the m25 solution to −864 °C with the m50. This research intends to be a starting point to generate an analysis methodology for construction solutions in the built environment, from the point of view of thermal comfort.

“…The incorporation of construction and demolition waste in concrete and cement mortars is already a common practice, and the aim is to ensure the construction industry assumes part of the waste it produces [11,12]. The goal of this stream is to promote the use of conglomerates by incorporating waste to produce so-called "green concrete".…”

The aim of the present work was to characterize the products obtained from the treatment of phosphogypsum residue by means of two recovery routes, and also to evaluate the concentrations of heavy metals and radionuclides in the materials obtained and their leachates. In this way, it is possible to determine how the most hazardous components of phosphogypsum behave during procedures until their stabilization through CO2 fixation. This study provides an initial estimate of the possibilities of reusing the resulting products from a health and safety risk standpoint and their potential polluting capacity. The phases resulting from the transformations were controlled, and the behaviour of standard mortars manufactured from the resulting paste lime was studied. In all cases, an additional control of the leachate products was performed.
