The stability of fresh concrete should be properly considered to ensure the quality of building
engineering while requiring its high flowability. The poor fresh state stability is detrimental to …

Cold weather conditions pose significant challenges to the performance and durability of
concrete materials, construction processes, and structures. This paper aims to provide a …

The molecular-scale structural changes in polycarboxylic superplasticizer (PCE) can
influence dispersion and water retention. Polycarboxylate superplasticizer, synthesized …

The biggest obstacle to become widespread 3D Printing Concrete (3DPC) is the insufficient
interlayer-bonding strength (IBS). The parameters affecting the IBS are classified as physical …

In this study, the strength and durability performance of 3D printing concrete mixtures
(3DPC) were examined in terms of the materials used in their production and printing …

In this study, the rheological properties of cementitious systems were investigated through
modeling studies on structural build-up and breakdown area. The area values were …

Concrete freeze-thaw damage is common in high-altitude regions. Adding an appropriate
amount of air-entraining agents (AEA) can improve the flowability of fresh concrete and the …

The synergistic effects of freezing-thawing (FRTH) cycles and chloride ion (Cl−) penetration
in concrete caused amplified damage and complex degradation mechanisms. This study …

In order to investigate the feasibility of using waste as an alternative binder in cement-based
materials, the effects of using recycled concrete powder (RCP), glass powder (GP), marble …

The effects of air-entraining admixture (AEA), curing process, and core direction were
studied as parameters in terms of their effect on the physicomechanical properties of 3D …
