Numerical Study of Shear Strengthening of Reinforced Concrete Beams using Strain-Hardening Cementitious Composites

Existing reinforced concrete (RC) structures can be strengthened using Strain Hardening Cementitious Composites (SHCC). The ability of SHCC in exhibiting a ductile response under tensile load due to strain­-hardening after crack initiation makes it a viable material to be used in, both, construction and retrofitting of concrete structures. The...

Influence of Interface and Type of Strain Hardening Cementitious Composite (SHCC) on Crack Control in SHCC-Concrete Hybrid Beams

A combination of conventional concrete members with innovative material such as Strain Hardening Cementitious Composite (SHCC) in the tensile zone, can exhibit better crack-width control. This is attributed to the bridging effect by the Polyvinyl Alcohol (PVA) fibers used in SHCC in combination with the special material composition containing...

3D printing of Geopolymer Concrete

In spite of the fact that there are many advantages of alkali activated materials (also called geopolymers) over the cement-based materials, geopolymer concrete has been used in the past for construction purposes on a very limited level. Among the many advantages of geopolymers compared with the cement-based materials is less CO2 emission, it...

Asphalt concrete stiffness prediction based on composition and binder properties

Asphalt concrete stiffness is currently only determined by tests in The Netherlands. A prediction model can be useful for mix design and verification purposes. In this paper existing asphalt concrete stiffness prediction models have been analysed. A database with 7 mixes has been build to assess these models. A study was performed on the...
