TL;DR: In this article, a self compacting concrete mixture with the use of ladle furnace slag as a filler and steel fibers as reinforcement was produced and tested in the laboratory, and the results showed that adequate consistency and workability was achieved, while compressive strength and durability were improved.

TL;DR: In this article, workability of fresh concrete used as material for additive manufacturing was measured according to four different tests: flow table, ICAR rheometer, Vicat and an experimental applied in the laboratory by measuring the electric power consumption of the motor that rotates the screw extruder.

TL;DR: In this article, the performance of concrete with electric arc furnace (EAF) steel slag as coarse aggregate and steel fiber reinforcement was investigated, and the results showed that EAF slag aggregates tend to form micro cracks at temperatures higher than 600 °C and the rate of strength loss is increased, there is a reduced risk of spalling.

TL;DR: In this article, the influence of electric arc furnace slag aggregates on the mechanical and gamma ray shielding properties of concrete mixtures were studied experimentally and the use of EAF slag and crushed limestone were used as aggregates.

TL;DR: In this paper, a Life Cycle Assessment (LCA) was carried out for industrial pavements, heavyweight concrete and pervious concrete paving blocks, where one m3 or one m2 of concrete was selected as functional unit and a cradle-to-gate approach was followed for the LCA, including material extraction, transport and production and placement, stating the limitations and system boundaries used.
