Abstract

In this study, carbon emission and energy consumption values of seventeen 3D printable concrete mixtures were investigated.

The carbon emission assessment of the mixtures was evaluated according to the use and amount of cement, fly ash, silica

fume, limestone aggregate, recycled concrete aggregate, polypropylene fiber and water reducing admixture. Carbon

emission assessment was made by using various embodied carbon and embodied energy values obtained from studies in

the literature. As a result, a reduction in CO2 emission values of the mixtures was measured with the use of silica fume.

Also, it was determined that with increasing use of polypropylene fiber, CO2 emission values increased by 3.6% (by 0.2%),

7% (by 0.4%) and 10.8% (by 0.6%). It was understood that the use of recycled concrete aggregate causes a decrease in

the carbon emission values of the mixtures. It was determined that the energy consumption values of 3D printable concrete

mixtures have a similar trend as their carbon emission values.
