Meeting the ever increasing concrete demand in a sustainable way is one of the critical challenges of cement and concrete industry. There are two major green concepts commonly implemented by the industry: (1) Building more efficient cement factories, or updating the existing ones, (2) providing concrete mixes with increased fractions of supplementary cementitious materials (SCMs). Updating a cement factory might be costly and time consuming. On the other hand, using SCMs provides an easy and sustainable solution yielding concretes with high workability, satisfactory ultimate strength, and improved long-term durability. Coal fly ash (FA) – the main by-product from the combustion of pulverized coal in thermal power plants - is one of the most popular SCMs due to its wide range availability and low cost. When used properly, the FA-PC binary systems result in satisfactory or superior engineering performance. As of today, the correlations on how green the FA-PC systems are to their engineering performance are limited. This work aims to bridge this gap for Turkish fly ashes. For this purpose, a database of compressive strength results of Turkish FA-PC mortars was prepared from available data on literature. As an environmental performance indicator the global warming potential (GWP) of the selected mixes was chosen. The GWPs of the mixes were calculated through life-cycle assessment (LCA)- a methodological framework that assesses the environmental impacts and resources (including raw materials, energy, etc.) used throughout a product’s life-cycle from raw material acquisition through production, use, maintenance, recycling, and ultimate disposal. For the GWP calculations, “GreenConcrete LCA” tool developed at UC Berkeley was used. As a final step, the compressive strength results were correlated to GWPs of the mortar mixes allowing the consumer to choose the most suitable and sustainable mix for a given task.

Life cycle assessment of a basic external drywall system in Turkey Akgül, Çağla; Özcelik, Gökçe (null; 2014-10-24) The construction sector, being one of the greatest consumers of raw materials, has been under the spotlight for many years in parallel to the increased environmental awareness. Specifically, building of walls are of critical importance. For each wall element, there are different manufacturing steps; but, in general, the emissions from a wall element are dominated by one or two manufacturing steps. For example, for concrete, both energy use and calcination in cement manufacturing are in focus; for clay brick...
Utilization of soda and beer wastes in cementitious systems Aleessa Alam, Burhan; Yaman, İsmail Özgür; Department of Cement Engineering (2009) To maintain the sustainability of cement and concrete production, there is a trend to use wastes in their production. Soda waste, generated by soda ash production process, and beer waste, generated by beer filtration process, are two locally produced wastes in Turkey and many other countries. The nature of these wastes, mostly their fineness, makes them possible to be used in concrete production, especially as a viscosity modifying agent in the self consolidating type of concrete. In this study, the additio...
Cement production by cement-bonded wood particleboard wastes Yilmaz, Mustafa; Tokyay, Mustafa; Yaman, İsmail Özgür (2016-01-01) To improve the sustainability of cement and concrete production, there is an increasing trend towards using industrial wastes throughout their production processes. The aim is to find new resources that can be used in any step of cement and concrete production and to find solutions to many problems related to the disposal of wastes. This article discusses the use of wastes generated from cement-bonded wood particle board (CB) manufacturing in cement production. CB waste, which basically contains wood chips ...
Incorporation of waste and pozzolanic materials as partial replacement for the development of sustainable concrete Hamza, Ali; İnce, Ceren; Sustainable Environment and Energy Systems (2018-1) Excessive production of cement due to modern construction practices frames cement as a leading pollutant of releasing significant amounts of CO2 in the atmosphere. The thesis begins with the examination of the alternative binding materials used as partial replacement to cement. Supplementary cementitious material, silica fume, is used as partial replacement to Portland cement whereas, waste materials, marble dust and crushed bricks, are used as partial replacement to the fine aggregates in this thesis. The ...
Embodied carbon assessment of residential housing at urban scale Kayaçetin, Nuri Cihan; Tanyer, Ali Murat (2020-01-01) A great majority of the previous research put extensive efforts on the evaluation of life cycle impacts and carbon footprint of single buildings. Analysis on single buildings often excludes components related with urban scale such as construction of infrastructure, distance to city centre and transportation. Research on neighbourhood-scale settlements is necessary to further develop the understanding of the environmental impact of built-environment.
