3D concrete printing of topological interlocking blocks
Materials & DesignIn this work the feasibility of combining the concept of topological interlocking assemblies (TIA) with 3D concrete printing is investigated. In TIA, blocks are arranged in a manner that, when kinematically constrained by a surrounding frame, all blocks ...

Rheological Modifiers in Optimizing Quick Nozzle Mixing Technology for 3D Concrete Printing [PDF]
Quickly mixing concrete at or near the printing nozzle is a new technique developed by the authors to improve 3D concrete printing technology. Quick nozzle mixing (QNM) solves the inherent problem in 3D concrete printing due to the opposing rheological ...

Journal of Asian Architecture and Building EngineeringOwing to the generation of waste during mining and processing, granite stone causes great damage to the environment. In this study, the broken granite waste and the stone powder were used as concrete coarse aggregate and “admixture” to make granite waste

Nonlinear finite element of FRP reinforced concrete structures.
, 2012 reinforcement is a non-corrosive alternative to steel and is gaining popularity for use in reinforced concrete structures exposed to corrosive environments. A major difference between the two reinforcing materials is their behaviour at failure.
