This study aimed to determine the criteria for designing a Community Center for social and urban development in the district of Veintiseis de Octubre, Piura. A quantitative methodology was used, including surveys of 382 inhabitants and analysis of previous studies. The results revealed a high valuation of green and wooded areas (62% of importance) and diversity of uses (43%), contrasting with low levels of satisfaction (9% and 20% respectively). The need for learning, sports and basic health care services was identified. The proposed design, distributed over three levels, responds to these needs by incorporating landscape elements and local materials. It concludes that the Community Centre designed effectively addresses infrastructure deficiencies and promotes social cohesion, in line with sustainable development objectives.

Masonry is a construction technique most used in buildings, one of the most common failures being the lack of adhesion between its units, so in this research the influence of the addition of lime or gray interior glue on the masonry has been evaluated. mortar adhesion. This investigation aimed to determine how much the addition of these materials influences the property of adhesion between the mortar and the brick, in an economical way with a significant improvement (Integral) in the Cajamarca region or in similar conditions. For this, adhesion tests were carried out on the mortar with a 1:4 proportion of cement and sand, with the addition of different proportions (1/8, 1/4, 1/2, 3/4) of lime or interior glue, performing 4 batteries of three units for each experiment, with a total of 90 batteries. The results indicated that the two additions provided more adhesion in all samples with respect to the standard sample, with the 3/4 lime sample being the one that improved by more than 90.68% with respect to the standard sample and with respect to the glue the maximum improvement was with the 1/8 sample of interior glue with 45.57%. These findings suggested that the addition of lime or interior glue can be an effective strategy to improve the adhesion property in 1:4 semi-industrial masonry mortars, with lime being the most effective addition.

This article addressed the need to improve the properties of concrete in the construction sector, in addition to mitigating the environmental impact generated by agro-industrial waste, such as whey, which is often disposed of in rivers and soils, where its high organic load contaminates the water and alters the properties of the soil. The methodology had an experimental design and was of the applied type, in which the impact of whey as an admixture in proportions of 1% and 2% by weight of water on the compressive strength of concrete was evaluated. A total of 36 concrete specimens were used, classified into three treatments according to the addition of whey (standard, 1% and 2%). Each treatment was evaluated using 4 specimens per day of curing (7,14 and 28 days). The results showed that the addition of whey caused a significant impact on the compressive strength of the concrete specimens. It was observed that the addition of 2% buttermilk increased the strength to a greater extent at 7 and 14 days; however, at 28 days, the addition of 1% buttermilk presented better results. It was concluded that whey can be used as an admixture in concrete, improving its compressive strength and offering an economical and ecological alternative in construction, promoting the reuse of agro-industrial by-products and more sustainable practices.

This research explores the design of convention centers through the lens of architectural flexibility, highlighting how this feature enhances functional adaptability and sustainability. Using a mixed-methods approach, four international and national cases were analyzed: Owensboro Convention Center (USA), Ágora Bogotá (Colombia), Bruges Meeting Center (Belgium), and the Lima Convention Center (Peru). A situational diagnosis of Arequipa identified a significant gap in infrastructure for large-scale events, limiting its competitiveness as an international destination. The results show that modular spaces, advanced technology, and sustainable strategies enable the creation of versatile infrastructure that respects the local context. The study concludes that the proposed design for Arequipa has the potential to boost the local economy, strengthen tourism, and position the city as a key player in the international event circuit.

The reasons why retaining structures may collapse due to heavy rains are similar to the reasons why landslides are triggered, taking into account that generally retaining structures are built to stabilize slopes or embankments. In addition, both the collapse of these structures, as well as landslides, can cause damage to surrounding infrastructure, property, and even to people near the fault zone. In the technical literature there are different types of research on case studies, alternatives to control the collapse of retaining structures induced by rains, associated with slope instability, which would have triggered landslides due to heavy rainfall, establishing alternatives for analysis, control and prevention to mitigate the disasters associated with this type of phenomena. This article aims to review and present research on case studies on the analysis, control and remediation of collapse of containment structures, as well as landslides, both triggered by rainfall, which are published in different specialized articles; therefore, different studies on the subject are presented in a summarized form, grouped into categories that cover different research, study, evaluation, analysis, validation, and monitoring methods. The categories considered are: A. Numerical analysis, B. Physical models, C. In situ tests – geophysical tests, D. Evaluation of rainfall, and E. Monitoring systems, so that they can be consulted in an organized way.

The growth of the construction industry has led to a significant increase in construction and demolition waste, necessitating sustainable alternatives for its management. This study evaluates the reuse of recycled coarse aggregate derived from the demolition of rigid pavements as coarse aggregate in new concrete structures, aiming to reduce waste and contribute to the sector's sustainability. The research is applied and explanatory, as it addresses the use of recycled concrete as coarse aggregate and analyzes its causal relationship with the physical and mechanical properties of concrete, using an experimental design with a quantitative approach. Five substitution percentages of natural coarse aggregate with recycled aggregate were analyzed: 0%, 10%, 20%, 30%, and 40%. Recycled coarse aggregate (RCA) significantly impacts the properties of 175 kg/cm² concrete, reducing its compressive strength by up to 11.48% and its workability from 9.53 cm to 1.27 cm as RCA increases from 0% to 40%. Beyond 30%, these properties fall outside acceptable standards. However, substitution proportions of up to 30% maintain acceptable properties, supporting sustainable practices with proper quality control. Higher percentages, however, significantly compromise structural performance and workability, limiting their application in projects requiring compliance with regulations. The use of recycled coarse aggregate is recommended in designs with compressive strength of f’c = 175 kg/cm² for substitution percentages of 30% or less.
