Abstract
One of the challenges in applying 3D-printing in the construction industry is the concrete mix design. This paper is a preliminary study on the design of a printable engineered cementitious composite (ECC). The cement was replaced with a combination of different contents of fly ash, slag, and silica fume, in two replacement levels, 50% and 75%, and their compressive strength and setting time were evaluated. To assure the flowability of the mixtures, the flow table results were set in a constant range of 19–20 cm. The results indicate that 50% cement-substitution by slag/fly ash resulted in the largest strength. The incorporation of slag shortened the setting time and improved the strength of ECC mixtures. The cement substitution by fly ash lowered the water demand, enhanced workability, and up to 50% cement replacement improved the compressive strength. The addition of 10% silica fume reduced compressive strength and extended the setting time.
