Lifecycle Assessment of Precast Concrete Elements in Sustainable Building Practices

Abstract

The construction industry is making a rapid transition towards more environmentally responsible practices, with the primary goal of minimising negative effects on the environment while preserving the structural integrity and performance of buildings. As a result of their potential to cut down on waste, improve efficiency, and minimise resource consumption, precast concrete pieces have emerged as an essential component in this transformation. The purpose of this research is to provide a full lifecycle assessment (LCA) of precast concrete elements within the framework of environmentally responsible building practices. When compared to the conventional cast-in-place concrete technologies, the life cycle assessment (LCA) helps to determine the environmental consequences that are involved with the manufacture, transportation, installation, use, and end-of-life phases of precast concrete structures. In this study, critical parameters such as energy consumption, carbon footprint, material efficiency, and waste generation are investigated throughout the lifecycle of precast concrete elements. This is accomplished through the use of extensive analysis. Although the production of precast concrete may include higher energy inputs due to manufacturing procedures, the findings indicate that the total environmental impact is mitigated by benefits such as reduced material waste, fewer on-site labour requirements, and better durability. These benefits take into account the fact that precast concrete is more durable than traditional concrete. In addition, the modular character of precast pieces enables greater design flexibility and the possibility of reuse, which further contributes to the achievement of sustainability goals.
