Effect of dose and types of the water reducing admixtures and superplasticizers on concrete strength and durability behaviour: a review

Journal of Civil Engineering and Management
As one of the concrete admixtures, water reducing admixtures and superplasticizers are usually used to reduce the mixing water volume and improve the performance of the harden concrete while maintaining better workability of the fresh concrete. However,

Mechanistic insights into the anion‐driven suppression of the initial cement reaction of tricalcium aluminate

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The hydration process of ordinary Portland cement (OPC) involves intricate interactions among ions in the pore solution, dissolving clinker phases, and precipitating hydrates. Tricalcium aluminate (C3A${\rm C}_3{\rm A}$) shows the highest reactivity of the cement clinker phases during the initial hydration stages of OPC. The kinetic control of

Tensile Performance of Prefabricated Tank Walls Connected Using Ultrahigh‐Performance Concrete

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Prefabricated tank structures are a widely used form of industrialized construction, yet the behavior of connections between precast segments remains insufficiently explored. Since the mechanical properties of these connections govern the structural performance of prefabricated tanks, this study introduces a novel joint detail employing cast‐in‐place ...

Mechanical and Physical Performance of Mortars Incorporating Crushed Hazelnut Shells as Partial Fine Aggregate Replacement

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
This study investigates the mechanical and physical properties of mortars incorporating crushed hazelnut shell (HS) as a partial replacement for fine aggregates. Mortar mixtures were prepared with varying water‐to‐cement (w/c) ratios ranging from 0.35 to 0.50 and HS dosages of 2.5%, 5%, and 7.5% by weight, along with reference mixtures without HS.
