Requirements on material properties for extrusion-based additive manufacturing mostly
focus on the rheological behavior of the cementitious material being printed. The layer …

One of the technical challenges for the extrusion-based 3D printed concrete is that the
requirements of green strength development are much different from ordinary concrete, due …

The flexural properties of 3D printed concrete specimens with recycled sand reinforced by
polyethylene (PE) fibres were investigated through four-point bending tests in this research …

Abstract Recycled Concrete Aggregates are highly porous and may therefore absorb more
water than natural aggregates. Several methods allow for the measurement of water …

Establishing an effective method to enhance the adhesion of mortar on recycled concrete
aggregate (RCA) is key to the utilization of RCA. In this paper, a novel and simple approach …

Abstract 3D concrete printing technology has seen rapid development due to its high
digitalization and automation. Using recycled sand from solid waste construction resources …

Owing to the high absorption capacity of recycled aggregate (RA), it is crucial to accurately
measure its saturated-surface-dried water absorption (WSSD), which largely affects an …

In this work, we reported the in situ biological modification of bacterial cellulose (BC) using
various sodium alginate with different molecular weights as the carbon source in the …

The water absorption of crushed concrete aggregates (CCA) has a major influence on
concrete workability. In order to determine the water absorption of CCA, a more porous …

The use of supplementary cementitious materials (SCM) is projected to increase because
they reduce the global warming potential of concrete. When cement is replaced with SCM …
