Description of air quality and environmental characteristics in primary school classrooms in the Community of Madrid.

Introduction: Air quality in schools is a concern at the European level, and few data have been published on the subject in the Community of Madrid.

Material And Methods: We conducted a longitudinal descriptive study on the presence and distribution of pollutants in four schools in Madrid selected on account of their location, exposure to traffic and proximity to green areas. We measured pollutants and assessed environmental characteristics in primary school classrooms.

Assessment of the mechanical and physical characteristics of PET bricks with different aggregates.

Construction and demolition waste, along with discarded PET plastic bottles, have evolved into a widespread global resource. However, their current disposal in landfills poses a significant environmental pollution challenge. This research is centered on evaluating the performance of cement mortar composed by larger PET particles in conjunction with sand, construction and demolition waste, and lightweight expanded polystyrene aggregates.

Assessment of the adequacy of mobile applications for disaster reduction.

Natural events continue to take a heavy toll on human lives. Added to this are the challenge of dynamic at-risk settings, uncertainty, and increasing threats, which demand holistic, flexible, and quickly adaptable solutions. In this context, mobile applications are strongly emerging as communication tools that can assist in disaster reduction.

Evaluation of Colombian Crops Fibrous Byproducts for Potential Applications in Sustainable Building Acoustics.

Local production of construction materials is a valuable tool for improving the building sector sustainability. In this sense, the use of lignocellulosic fibers from local species becomes an interesting alternative to the development of such materials. As it is thought that the properties of fiber-based materials are dependent on the fibers properties, the knowledge of such properties is fundamental to promote materials development.

Microstructural and Thermo-Physical Characterization of a Water Hyacinth Petiole for Thermal Insulation Particle Board Manufacture.

Water Hyacinth () is a dangerous and invasive aquatic species, of which global concern has sharply risen due to its rapid growth. Despite ample research on its possible applications in the construction field, there are no clear references on the optimal use of the plant in finding the most efficient-use building material. In this paper, a microstructural and chemical characterization of the Water Hyacinth petiole was performed, in order to find the most efficient use as a construction material.
