Concrete cracking has a negative impact on the durability of structure. Pre-implanting microcapsules containing healing agents into concrete are expected to induce cracks self-heal. However, self-healing effect can potentially be influenced by several environmental conditions, thus limiting its applications. To address these challenges, we developed new type water-absorbing microcapsules, using calcium alginate hydrogel as wall material and an adhesive epoxy polymer core material, improve...

Abstract Iron tailings remain the environment‐damaging waste from iron ore, and high porosity porous ceramics are an attractive material to “turn into treasure.” To improve thermal conductivity, with silicon carbide content have been prepared by carbothermal reduction sintering process using argillaceous fine‐grained silica content. The reaction mechanism components properties of samples in investigated. results show that mainly SiO 2 Fe O 3 liquid phase is generated rapidly between 1200°C...

Spark plasma sintering is a new technology for preparing ceramic materials. In this article, thermal-electric-mechanical coupled model used to simulate the spark process of boron carbide. The solution thermal-electric part was based on charge conservation equation and energy equation. A phenomenological constitutive (Drucker-Prager Cap model) densification carbide powder. To reflect influence temperature performance, parameters were set as functions temperature. experiments conducted at four...
Numerical simulation is an important method to investigate powder-compacting processes. The Drucker–Prager cap constitutive model often utilized in the numerical of powder compaction. contains a number parameters and it requires series mechanical experiments determine parameters. inverse identification methods are time-saving alternatives, but most procedures use flat punch during process. It does not reflect densification behavior under shearing stress state. Here, approach for developed by...
