- For many years, the design of reinforced concrete structures in the U.S. has been dominated by the use of steel reinforcement with a specified yield strength, fy, of 60 ksi.
- Reinforced concrete (RC) columns typical of existing structures often exhibit premature failures during seismic events (i.e., longitudinal bars buckling and shear interaction mechanisms) due to the poor quality concrete and the absence of proper seismic details in the potential plastic hinge region.
- The internal curing of cementitious composites (CCs) has been a subject of supreme importance for the past few years.
- When a concrete structure is built on the acid sulfate soils found around volcanic zones, the concrete may be deteriorated due to chemical attack.
- Nanoparticle modifications of glass-ionomer cement are interesting research subjects.
- In recent years, steel-concrete composite shear walls have been widely used in enormous high-rise buildings.
- Alkali-activated slag (AAS) is a promising alternative to ordinary Portland cement (OPC) as sole binder for reinforced concrete structures.
- Considering its superior engineering properties, ultrahigh performance concrete (UHPC) has emerged as a strong contender to replace normal strength concrete (NSC) in diverse construction applications.
- The contribution of aggregate interlocking and dowel force in shear strength of reinforced concrete beams was topic of research for many years.
- Concrete is the commonly used manufactured building material in the world, owing to its usefulness and relatively low cost.
- multi-scale characterisation of the transport process within cementitious microstructure possesses a great challenge in terms of modelling and schematization.
- Both clays and calcium silicate hydrates(the main hydration products of Portland cements) exhibit a microstructure made up of lamellar particles.
- Using coal gangue (CG) as supplementary cementitious materials (SCMs) is believed to be one of the effective strategies for CG disposal.
- Structures assembled with cross-laminated timber (CLT) panels, and designed to resist gravity and lateral loads, are being considered as viable options for low-rise to mid-rise buildings.
- Nowadays, geopolymer with alkali activation binders are introduced as alternative environmentally friendly construction materials to the ordinary Portland cement for solving the carbon dioxide emission and high energy consumption problems.
- To mitigate the potential environmental pollution of discarded tires and waste carbon fiber reinforced polymer (CFRP), the present study investigates the feasibility of collaborative use of these recycled materials, which is called recycled CFRP fiber reinforced rubberized concrete (RFRRC).
- Premature debonding is the major barrier to FRP (fibre-reinforced polymer) utilization in FRP-reinforced concrete structures and restricts the promotion of structural bearing capability.
- A critical area overlooked in previous research on pumice is understanding how its physical characteristics influence its behavior as a supplementary cementitious material (SCM).
- A considerable number of investigations have been conducted on the physical and mechanical properties of concrete made with crushed calcareous sand at room temperature.
- Hollow glass microspheres (HGMs) containing a large amount of recycled glass are used to develop ultra-lightweight engineered cementitious composites (ECCs), which are more sustainable comparing to standard ECC.
- Carbon dioxide (CO 2 ) capture technologies such as post-combustion capture, oxygen combustion and isolated calcination and mineral sequestration of CO 2 in precast concrete products through accelerated CO 2 curing appear to be promising avenues for managing CO 2 emissions by the cement and concrete industry.
- the recent design of high ductile fiber-reinforced ECC (engineered cementitious composite), optimizing both processing and mechanical properties for specific applications is critical.
