TL;DR: In this article, the authors present a literature review on the environmental impact of cement production and identify the main alternatives to improve the environmental performance of the cement production process, such as energy efficiency, alternative fuels, clinker substitution, and carbon capture and storage.

TL;DR: In this paper, the authors provided an assessment of the embodied and operational energy during construction and occupation phases of three main construction methods on social dwellings in Ecuador, including isolated concrete forms (ICF), concrete Load Bearing Walls (LBW), and traditional beams-columns Confined Masonry (CM) systems.

TL;DR: In this article, the authors identify the main risk factors that are threats to meet the objectives of tunnel construction projects by using the Chilean construction industry as a case study and propose a methodology to evaluate risk factors in this type of project.

TL;DR: Results did not provide evidence of significant statistical differences between different probability distribution used with respect to the mean project duration obtained using PERT scheduling as compared to the discrete event simulation model.
