Inorganic powder encapsulated in brittle polymer particles for self-healing cement-based materials

Many types of healing agents have been investigated. These agents are processed in different ways, such as adhesive polymer in capsules or hollow fibre glasses, bacteria in porous aggregates and geo-materials directly incorporated in the cementbased materials. In this study, sodium silicate powder is encapsulated in polystyrene particles ...

Quality Assessment of Printable Strain Hardening Cementitious Composites Manufactured in Two Different Printing Facilities

Over the past few years, several studies have shown the potential of three-dimensional concrete printing (3DCP) for applications in building and civil engineering. However, only a few studies have compared the properties of the fresh printing material and the quality of the printed elements from different printing facilities. Variations in the...

Design and analyses of printable strain hardening cementitious composites with optimized particle size distribution

Since the advent of three-dimensional concrete printing (3DCP), several studies have shown the potential of strain hardening cementitious composites (SHCC) as a self-reinforcing printable mortar. However, only a few papers focus on achieving sufficient buildability when developing printable SHCC. This study investigates the role of the...

3D printable strain hardening cementitious composites (3DP-SHCC), tailoring fresh and hardened state properties

With the introduction of 3D concrete printing, research started on how to include reinforcement in 3D printed structures. Initial studies on the implementation of strain hardening cementitious composites (SHCC) as self-reinforcing printable mortars have shown promising results. The development of this new type of SHCC comes with additional...

Repair concrete structures with high-early-strength engineered cementitious composites (HES-ECC): Material design and interfacial behavior

Aimed at realizing the effective strengthening and durable repair of concrete structures, particularly in emergencies like traffic interruption triggered by broken roads and damaged bridges, nine groups of specimens were designed and tested in this paper to develop the high-early-strength Engineered Cementitious Composites (HES-ECC) featured...

Experimental Analysis on ECC Schemes for Fault-Tolerant Hybrid Memories

Hybrid memories are one of the emerging memory technologies for future data storage. These memories are structured by integrating non-CMOS nanodevices (e.g., carbon nanotubes, single electron junction, organic molecules) with CMOS devices. Non-CMOS nanodevices build up crossbar-based memory cells, whereas CMOS devices form peripheral circuits....

Towards a fault tolerant RISC-V softcore

As predicted by Gordon E. Moore in 1975, the number of transistors has doubled every two years over the last decades. This technology scaling led to a higher performance of Integrated Circuits (ICs) like processors, but have also made these devices more susceptible to Single Event Effects (SEEs). SEEs are caused by transistors changing state...
