Abstract 3D printing is a promising technology of great significance in several industries
including construction. In line with the urgent need to reduce the environmental impacts of …

The use of fly ash in concrete dates back to the late 20 th century and its advantages and
disadvantages had been widely researched. Despite the broad based research carried out …

The rheology is an effective tool to characterize workability, consistency, flowability, and
predict stability, pumpability, shootability, pressure of formwork, multi-layer casting. This …

Early stage and fresh properties of cementitious materials are critical to ease of placement
and durability. This study investigated the potential of biochar, prepared by pyrolysis of …

The primary goal of concrete mixture design is to strike a balance among workability,
compressive strength, durability, economic efficiency and sustainability. In this paper, for a …

Abstract The Cemented Paste Backfill (CPB) technology can provide effective solutions to
mining-related environmental and safety problems, and access to achievement of green …

Workability and rheology in alkali-activated materials (AAMs) have been scarcely studied
and differ substantially from ordinary Portland cement (OPC) systems. This study aims to …

Extrusion-based concrete 3D printing is at its infancy and many aspects of this new
technology need to be thoroughly investigated to pave the way for its widespread use in …

This study aimed to expand the knowledge on the application of the most common industrial
byproduct, ie, fly ash, as a supplementary cementitious material. The characteristics of …

Printable alkali-activated mixtures, which are homogeneous under pressure and achieve
buildability in 3D concrete printing by extrusion-based layer deposition are developed. A …
