Applying concept of 3d printing concrete in wind tower construction

Abstract

Although a most prominent material in contemporary construction practice due to its’ obvious advantages, concrete incorporates a number of drawbacks. It is one of the most advantageous principles for decades to enable a large-scale on-site application of this materials with acceptable properties, needed to withstand specific conditions. A concept of 3d printing concrete presents a promising ground for further improvement of this principle. While maintaining as much as possible of the prerequisite and common properties to answer the construction demands, this material has to evolve as much as possible to fulfill the 3d concept, which would, in turn, pave a way for next level of its wide range of construction applications. This paper aims to contain main principles of 3d printing concrete, discussing the main goals and the drawbacks that have to be addressed and solved prior to wider application. Also, wind tower construction, as a specific construction will be discussed as a potentially promising ground for this old construction material dressed in a new suit.

Iako je najčešće primenjivan materijal u savremenoj građevinskoj praksi zbog svojih očiglednih prednosti, beton poseduje izvestan broj nedostataka. Jedan od najvažnijih principa već decenijama je da se omogući masovna upotreba ovog materijala na gradilištima sa prihvatljivim svojstvima, neophodnim da bi on podneo specifične uslove. Koncept 3d štampe betona predstavlja obećavajuću osnovu za dalje poboljšanje ovog principa. Zadržavajući što veći broj preduslova i osnovnih svojstava da bi se zadovoljili konstruktivni zahtevi, ovaj materijal mora umnogome evoluirati da bi zadovoljio 3d concept, što bi, zauzvrat, popločalo put do sledećeg nivoa njegovog širokog obima primene u graditeljstvu. Cilj ovog rada je da sadrži osnovne principe 3d štampe betona, diskutujući glavne ciljeve I nedostatke koji se moraju sagledati i rešiti pre šire primene. Takođe, konstrukcija stuba vetrogeneratora, kao specifična konstrukcija biće diskutovana kao potencijalno obećavajuća osnova za ovaj stari građevinski materijal odeven u novo odelo.
