The use of lightweight concrete (LWC) for structural and non-structural applications has
attracted great interest in recent years. The main benefits include reduced deadload of …

Abstract 3D concrete printing technology of cementitious materials is challenging in many
aspects. Despite the workability and mechanical properties of a mix and hardened concrete …

Technological developments in construction have led to an increase in the use of 3D
modelling using CAD environments. The popularity of this approach has increased in …

Despite the rapid development of 3D printing technology for cement composites, there are
still a number of unsolved issues related to extrusion printing. One of them is proper mix …

The design of proper mixes for 3D concrete printing has been already a subject of many
studies. Modification to mixes aim to obtain certain properties (extrudability, workability …

This study determines the effect of spent garnet as a replacement for natural sand in 3D-
printed mortar at early ages. Five mixes with different spent garnet amounts were prepared …

Foundation piles that are made by concrete 3D printers constitute a new alternative way of
founding buildings constructed using incremental technology. We are currently observing …

The purpose of the external walls is to secure the internal microclimate of the building.
External walls not only must have proper strength and durability but also prevent heat …

Use of recycled materials and incorporation of sustainable development ideas are one of the
most popular trends in civil engineering. The 3D concrete printing technology which has …

The paper presents the maturity curve for estimating the in-place early-age compressive
strength of concrete. The development of appropriate maturity curve is a complex process. It …
