La productividad es uno de los retos más importantes a los que se enfrenta el sector de la construcción, ya que las ineficiencias provocan costes y tiempo excesivos. Asimismo, la falta de adopción de nuevas tecnologías y la limitada inversión en la digitalización de la industria generan que surjan una serie de problemas relacionados con la recopilación de datos para la productividad en campo. Esta situación crea desafíos en la identificación de áreas para mejorar el rendimiento debido a datos inexactos, errores de interpretación de datos y pérdida de información.

Por esta razón, el presente trabajo se enfoca en la digitalización de los procesos de recolección de datos de productividad laboral durante las etapas estructurales y de terminación de proyectos de construcción de viviendas multifamiliares, mediante el uso de la herramienta digital Raken. La metodología seleccionada incluye (A) revisión de la literatura y encuestas de expertos sobre el tema, (B) evaluación del estado actual de la recopilación de datos de productividad en el sitio para las etapas estructurales y de acabado, (C) desarrollo de un procedimiento para reducir el tiempo requerido para la recopilación de datos de productividad, y (D) implementación del procedimiento propuesto. Finalmente, el resultado es una reducción de datos Tiempo de recogida del 64,40% para el casco estructural y el 60,56% para la etapa de llegada, con el métrica siendo el tiempo en HH. Así, se concluye que, a través de la digitalización, la Hora de la recopilación de datos en el sitio se reduce.

Today, adobe houses are exposed to seismic movements, since they were built in a traditional way without professional supervision. This implies establishing an optimal reinforcement method using uniaxial, biaxial and electrowelded geogrids for houses built 30 years ago. First, the characterization of the clay soil was carried out in order to know the physical properties and determine the appropriate dosage for the elaboration of the adobe blocks. Subsequently, these were used in the construction of 12 walls, which were compared by means of the diagonal compression test to determine the resistance of each of them. The results show that the electrowelded mesh had a better stress behavior with 1.71 kg/cm2 unlike the other two reinforcements mentioned who presented a result below 1.60 kg/cm2. Thus concluding that the electrowelded mesh is the optimal technique for reinforcing adobe houses in the town of Yanamarca-Peru.

The objective of this research is to evaluate the level of coastal resilience in residential buildings of the AAHH La Florida Baja, Chimbote 2024. The research method is quantitative and descriptive. The design is non-experimental. The technique used is observation in the AAHH La Florida Baja. The data collection instrument is the observation sheet structured in the three specific objectives; determine the vulnerability, identify the adaptive design and characterize the green infrastructure of the residential buildings of the AAHH La Florida Baja, in this, the observation sheet is composed of dynamic marking boxes qualified by an ordinal scale from 1 to 4, where the level of resilience of the residential buildings located in the coastal strip of the AAHH La Florida Baja - Chimbote is determined. The study determined that "The coastal communities of Florida Baja Chimbote face an uncertain future due to the lack of resilience of residential buildings to extreme weather events." Therefore, the level of coastal resilience of residential buildings in the AAHH. Low Florida is low.

This paper evaluates the impact of the addition of maguey fibers and prickly pear gel on the compressive strength of adobe, a widely used building material in rural areas of Peru. In the district of Chacabamba, Huánuco, where 87.3% of the houses are made of adobe and face high rainfall conditions, improving the structural strength of this material is essential. Four adobe mixtures were prepared: a standard design without additives and three mixtures with 2.5% maguey fibers together with 5%, 10%, and 15% prickly pear gel, respectively. Compression tests on individual units and piles showed that the design with 2.5% maguey and 15% prickly pear gel achieved an average strength of 15.12 kg/cm² in units and 10.09 kg/cm² in piles, exceeding the standard design by 44.55% and 53.11%, respectively. These results indicate that the proposed mixture not only meets, but exceeds the minimum standards of Norma E-080 for compressive strength in units and piles. This approach with natural additives provides an effective, economical and sustainable alternative to improve the structural stability of adobe in rural communities vulnerable to extreme weather conditions.

The research sought to replace the silica powder with the fine aggregate, because in the Currently the construction sector is looking for new technologies to generate more concrete resistant and durable. A quantitative experimental research methodology is used given What, we will apply different percentages of silica powder in different test tubes to find the strength and bending point in 7, 14 and 28 days for concrete. With 12% silica powder in the fine aggregate and superplasticizer, good results, with specimen 2 being 28 days old the one that generates the greatest compression, exceeding at 14.44% of what was established and for the bending of beam 2 with a modulus of rupture of 74kg/cm² Comparing our work with that of Malathy (2022) we find that the resistance increases proportionally by replacing the silica powder, given its cohesion of the material, allowing better features. It is recommended to use designs greater than 320 kg/cm².

The purpose of this research is to determine the compressive strength of concrete f'c= 210 kg/cm² with addition of 4%, 8% and 12% of diatomite and kaolin; for this purpose, a quasi-experimental design of the applied type was applied considering a sample of 63 cylindrical concrete specimens; in which, 9 specimens belong to the standard concrete and 54 specimens to the concrete with addition of diatomite and kaolin in percentages of 4%, 8% and 12%. Likewise, the values obtained for the compressive strength of the standard concrete at 28 days of curing were 247.44 kg/cm² and of the concrete with addition of diatomite at 4%, 8% and 12% were 320.49 kg/cm², 180.32 kg/cm² and 117.46 kg/cm² respectively; however, the values of the concrete with addition of kaolin at 4%, 8% and 12% were 303.44 kg/cm², 299.65 kg/cm² and 247.91 kg/cm² respectively. Finally, it is concluded that concrete with diatomite addition at 4% increases the compressive strength of concrete by 29.52% with respect to the standard concrete; similarly, concrete with kaolin addition at 4%, 8% and 12% improves the compressive strength by 22.63%, 21.10% and 0.19%, respectively.

This study aims to evaluate the use of calcite as a natural additive to enhance the axial compressive strength of concrete with a design strength of f'c = 210 kg/cm². Crushed calcite stone was incorporated at 1%, 2%, and 3% of the cement weight. An experimental design with a quantitative approach was used, with a sample of 36 standard cylindrical specimens. Data was collected from laboratory records at a university's concrete laboratory, where tests on both aggregates and concrete were conducted. The results were analyzed using direct observation, university-provided laboratory protocols, and Excel software. The compressive strength was evaluated at 7, 14, and 28 days, showing that the most effective addition was 3%, which increased the concrete strength by 7.92% after 28 days of curing. Additions of 1% and 2% crushed calcite stone increased strength by 0.53% and 5.86%, respectively
