Shear friction capacity of self-consolidating concrete
Revista IBRACON de Estruturas e Materiais, 2020 An experimental research was developed to evaluate shear transfer in self-consolidating. Three concrete mixes were prepared, one conventional and two self-consolidating, differing on the proportion of the coarse and fine aggregate used.

Effect of Recycled Aggregate Quality on the Bond Behavior and Shear Strength of RC Members
Applied Sciences, 2018 During the aggregate crushing process, natural aggregate and clinging mortar from existing concrete will inevitably produce small cracks and weak bonds between the aggregate and the existing cement mortar.

The Utilisation of Shredded PET as Aggregate Replacement for Interlocking Concrete Block [PDF]
E3S Web of Conferences, 2018 The consumption of plastic has grown substantially all over the world in recent years and this has created huge quantities of plastic-based waste. Plastic waste is now a serious environmental threat to the modern way of living, although steps were taken to reduce its consumption.

Multi-scale modeling of aggregate interlock phenomena in concrete
, 2021 In concrete structures, opened cracks contribute significantly to the transfer of shear and normal stresses through the contact forces occurring between fractured surfaces. Such contact forces are due to protruding asperities, engaged by interlocking and friction.

Experimental investigation on shear resistance of self-consolidating concrete beams
Revista IBRACON de Estruturas e Materiais, 2019 Self-consolidating concrete stands out for its high fluidity and stability, which are obtained by the reduction of the coarse aggregate dimensions and content in the mixture and also by the addition of superplasticizer and viscosity modifiers.

Assessment of one-way shear design of RC elements subjected to axial tension
Case Studies in Construction Materials, 2021 The Shear failure of reinforced concrete is brittle with no warning. In addition, tensile forces could widen the concrete cracking and cause premature failure. Thus, worsen the situation, which could have disastrous consequences in many cases as shown in

Shear strength of slender SCC beams - possible differences from VC beams
Revista IBRACON de Estruturas e MateriaisIn comparison with vibrated concrete (VC) of the same strength class, self-compacting concrete (SCC) typically has a lower coarse aggregate content and, eventually, a smaller maximum aggregate size.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Finite Element Modelling of geogrids in stabilisation function - Comparison study [PDF]
E3S Web of ConferencesFinite element methods (FEM) are commonly used in geotechnical designs. These methods become particularly valuable when complex multistage scenarios with a variety of interactions need to be considered.
