Impact of air entrainment on the microstructure and mechanical performance of high performance mortar [PDF]

, 2014
At the Magnel Laboratory for Concrete Research an intensive vacuum mixer which can regulate the air pressure is available. As such the amount of entrapped air in cementitious materials can be varied.

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

Internal curing of cement pastes by superabsorbent polymers studied by means of neutron radiography [PDF]

, 2017
Autogenous shrinkage is a problem in cementitious materials with a low water-to-binder ratio. When the internal relative humidity decreases due to the ongoing hydration reaction and selfdesiccation, autogenous shrinkage takes place if no external or ...

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 ...

The Effect of Granite Waste Powder as a Cement Substitute on the Mechanical Properties and Microstructure of Mortar

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Granite is extensively used in the construction industry; however, substantial solid waste is produced during production. This study focused on the feasibility of replacing cement with granite powder (GP) in cement mortar by investigating various properties, like consistency, water retention, density, setting time, compressive strength, and flexural ...

Monitoring the reduction in shrinkage cracking of mortars containing superabsorbent polymers [PDF]

, 2017
Ultra-high performance concrete (UHPC) is characterized by a low water-to-cement ratio, leading to improved durability and mechanical properties. However, the risk for autogenous shrinkage and cracking due to restrained shrinkage increases, which may ...

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.
