Bu çalışmada, mineral katkı içeren 3D baskı harçlarının yazdırıldıktan sonra zamana bağlı kuruma büzülme davranışları araştırılmıştır. Harçların bileşiminde mineral katkı olarak %0, %10 ve %20 oranlarında uçucu kül kullanılarak farklı harçlar tasarlanmıştır. Mineral katkı çimentoyla ağırlıkça yer değiştirme yöntemine göre kullanılmıştır. Harçlar 3D yazıcıda tek katman olarak baskılandıktan sonra laboratuar ortamında 40 güne kadar boy değişimleri ölçülmüştür. Her bir ölçümün ilk boya oranına göre kuruma büzülme oranları belirlenmiş ve karşılaştırılmıştır. Elde edilen bulgulara göre uçucu kül kullanımıyla kontrol harçların büzülme oranları önemli derecede azaltılmıştır.</p></abstract>

                            <p>Three-dimensional (3D) printers have brought a new dimension to the construction industry. The natural drying shrinkage of hardened cement paste in 3D-printed mortars poses a great risk in terms of shrinkage behavior due to their very high cement/fine aggregate ratios. In this study, time-dependent drying shrinkage behavior of 3D printing mortars containing mineral additive was investigated. Different mortars were designed by using 0%, 10% and 20% fly ash as mineral additives in the composition of the mortars. Mineral additive was used according to the weight displacement method with cement. After the mortars were printed as a single layer in a 3D printer, their length changes were measured in the laboratory environment for up to 40 days. Drying shrinkage rates were determined and compared according to the initial dye ratio of each measurement. According to the findings, the shrinkage rates of the control mortars were significantly reduced with the use of fly ash.</p></trans-abstract>
