This work shows the results of an experimental campaign aimed at selecting earth-based
sustainable mixes for 3D printing. For this scope, 18 mixes were realized, varying the types …

This work studies the effect of substitution rate and types of recycled concrete powders
(RCPs) on the rheology over time, setting time, and 1 day compressive strength of cement …

The in-plant use of recycled aggregate concrete derived from precast rejects (termed PRAC
herein) can promote a circular economy in the precast industry. However, the environmental …

It is well known that the fine aggregate's content and properties have a significant influence
on the plastic viscosity of mortar made with them. However, the underlying mechanisms of …

As a two-phase material composed of liquid slurry and solid particles, the local blocking
phenomenon may occur in the pouring process of fresh self-compacting concrete (SCC) and …

Fine recycled concrete aggregates (fRCA, 0–4 mm) are produced from demolished concrete
structures and consist of natural aggregates and old cement mortar. The presence of old …

Featured Application In the present work, the authors investigated the properties and
durability of mortars produced by replacing 100% of natural sand with recycled aggregate …

Cement replacement materials are used in self-compacting concrete mixes to reduce the
cement content and hence its environmental effect. This article examined the effects of …

This study aimed to develop a rheometer prototype and define a procedure for adjusting the
automated control of the fresh state of concrete. Sixteen batches were produced, and their …

Very large quantities of stone waste sludge are disposed in exhausted quarries and have a
very low reuse rate to date. The paper considers the possibility of using these types of …
