Radiographic changes in the maxillary sinus following closed sinus augmentation
Journal of Periodontology, EarlyView.Abstract Background The primary objective of this study is to evaluate the accuracy of 3‐dimensional (3D) imaging in detecting radiographic and morphological graft changes compared to traditional 2‐dimensional (2D) imaging. Additionally, the study aims to assess the distribution of graft material and the extent of resorption occurring between baseline ...

Shrinkage properties of steel fiber reinforced concrete- A review
Applications in Engineering ScienceCracks induced by concrete shrinkage may allow corrosive agents to penetrate steel reinforced concrete and deteriorate the reinforcement. Adding randomly distributed steel fiber to concrete can reduce shrinkage and prevent the initiation of cracking ...

Cement, 2022 In this work, we show that non-superabsorbent, thermo-responsive poly(N-isopropyl acrylamide) (PNIPAM) hydrogel particles (< 250 μm) can reduce autogenous shrinkage in cement paste and improve early-age stiffening that can be caused by traditional ...

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 ...

Tracing the evolution of root coverage: Clinical milestones leading to a minimally invasive era
Journal of Periodontology, EarlyView.Abstract Over the past several decades, periodontal plastic surgery has undergone a remarkable transformation, particularly in the field of root coverage procedures. This review traces the historical evolution of surgical techniques, from the early use of pedicle flaps and free gingival grafts (FGGs) to the development of bilaminar approaches ...

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 ...

Analysis of flow rates in cracked reinforced concrete
Structural Concrete, EarlyView.Abstract According to Eurocode 2, part 3, autogenous self‐healing of separation cracks with a width ≤0.20 mm can be considered under certain hydraulic conditions. However, practical experience shows that healing does not always reliably occur even when this crack width is maintained.

The influence of granulation on lightweight aggregate on early autogenous shrinkage of high strength concrete [PDF]
, 2013 Early autogenous shrinkage of high strength concretes is relatively large. It can be reduced by using internal water reservoirs. Lightweight aggregate was used for internal water reservoir.
