Utilization of waste foam concrete with MPCM as a substitution material for cement in mortars

Given the rising popularity of foam concrete (FC) for both structural and insulating purposes, evaluating the feasibility of recycling after its lifespan is crucial in the context of the growing emphasis on sustainable building practices. One approach to recycling FC incorporating microencapsulated phase change material (MPCM) involves...

Sodium silicate/polyurethane microcapsules synthesized for enhancing self-healing ability of cementitious materials: Optimization of stirring speeds and evaluation of self-healing efficiency

In this study, stirring speeds during the synthesizing process of the sodium silicate/polyurethane microcapsules were optimized. The yield values of microcapsules at different stirring rates were evaluated. Based on the yield values and shape of microcapsules, optimized microcapsules were obtained. The measurements of the shell thickness of...

Smart Crack Control in Concrete through Use of Phase Change Materials (PCMs): A Review

Cracks in concrete structures present a threat to their durability. Therefore, numerous research studies have been devoted to reducing concrete cracking. In recent years, a new approach has been proposed for controlling temperature related cracking—utilization of phase change materials (PCMs) in concrete. Through their ability to capture heat,...

Crystallization & Encapsulation in multicomponent mixtures

In this dissertation crystallization and microencapsulation processes are used to produce multicomponent particulate products with different functionalities (improved stability, controlled release, protection from environment, etc.) and their performance is assessed. Additionally, the interactions between the components in the processes are...

Mechanical properties and biocompatibility of poly(methyl methacrylate) bone cement containing microencapsulated tissue adhesive

One of the most broadly reported self-healing schemes is that pioneered by White and Sottos et al. in which a polymer matrix is co-embedded with a catalyst and microcapsules containing a reactive healing agent. Although this field has been steadily growing over the past 10 years, little discussion of extension into biomaterials has taken place...

Life extension in protective coatings via self-healing technology

As the field of self-healing materials continues to grow, novel self-healing concepts and chemistries are being developed for a variety of applications including coatings. Self-healing functionality is typically considered for incorporation in coatings to solve two basic challenges including restoration of aesthetic properties and restoration of...
