Nanomateriales en obra de construcción: estado actual de la prevención de riesgos laborales

Abstract

The use of engineered nanomaterials (ENMs), understood as materials whose main constituents presentone or more external dimensions in the size range from 1 nm to 100 nm, allows to improve the propertiesof a variety of materials and products widely used in the construction sector. Nanotechnology is a keydriver for technological innovation in construction sector, where an exponential increase in its applicationis expected, with some predicting that 50% of building products will be nano-enabled by 2025. Despiteexpected growth expectations, its application has been hampered by the current degree of uncertaintyregarding the potential effects of NMMs on human health and the environment. This document shows thecurrent status of the recommendations to face this new emerging risk in construction works.
