Using 3D printing technology in the construction industry is growing rapidly due to its numerous advantages. However, understanding various influencing factors on this technique crucial. Among these, concrete pumping process can significantly impact printed concrete's properties. The results indicate that alter structure of void spaces, reduce air content, and increase compressive strength concrete. Mainly, mechanisms mechanical entrapment, reduction content hydration kinetics respectively cause these changes pumping. In control samples, fresh decreased by 47% increased 4.3%. creation stable bubbles using air-entraining agents lead a decrease change strength. By 0.12% agent, drop reached about 23–25%. It also appears that, depending amount entrained mixture, affect flowability differently.
