“…The incorporation of nanoclay into concrete has several beneficial effects, including reducing building energy consumption, enhancing thermal insulation properties, improving thermal stability, fire resistance, thermal performance, behavior, resistance to cracking and degradation, and decreasing thermal conductivity, which leads to effective insulation and lower energy consumption during heating and cooling periods [33]. Nanoparticles contribute to the development of strength in cement-based materials by enhancing the hydration process of cement, resulting in the formation of calciumsilica-hydrate (C-S-H) and improved overall strength [99].…”

In construction engineering, there is currently a strong emphasis on finding construction materials, mainly the binder which plays a crucial role, that meet multiple criteria, including sustainability, cost-effectiveness, durability, and reduced environmental impact. However, there is a growing interest in exploring alternatives to traditional binders to address the limitations associated with their production and use. One such alternative is the use of naturally occurring materials like clay. Clay deposits are abundant and widely available, making them a sustainable resource for construction applications. Moreover, clay contains significant amounts of silica and alumina, which are key components for inducing pozzolanic reactions that contribute to the strength and durability of concrete. In recent studies, nanoclays (NCs) have emerged as a promising addition to construction materials as supplementary cementitious materials. These nanoparticles possess unique properties that can enhance the performance of concrete. Nanoclays significantly improve the compressive strength, sustainability, and durability of concrete structures. The high surface area and reactivity of nanoclays facilitate better bonding between cement particles, resulting in enhanced mechanical properties. This chapter aims to discuss the state of the art on performance enhancements of building materials that employ different types of nanoclays in place of conventional binders and the future trends.

“…Nanoparticles have been shown to improve the microstructure of concretes by filling the pores within the cement to increase its packing level, providing increased mechanics as the nanoparticle percentage increases. [65,66] William and coworkers similarly found that compressive strength in explanted vertebral bodies treated with PMMA and PMMA supplemented with HA decreased in groups treated with the 1g:3g (PMMA:HA) group compared to the 1g:1g and 1g:2g groups. [67] While the compressive mechanics of mPOC-40HA are promising, additional tensile testing would need to be evaluated as increasing HA concentration has been shown to decrease tensile and bending characteristics.…”

Vertebral compression fractures due to osteoporosis are commonly treated with bone cements based on the non-degradable, mechanically stiff poly(methyl methacrylate) (PMMA), which relies on peroxide-initiated polymerization to quickly set the cement at the cost of high exothermic temperatures. Recently, there has been interest in developing degradable, bone mechanic-matching alternatives that pursue physiologically induced polymerization to both augment the handling of the material before application and to reduce high localized temperatures that may lead to tissue damage. Herein, we report the development and material characterization of a thermoresponsive, degradable bone cement that utilizes the azo-based radical initiator 2-2ʹ-azobis (4-methoxy-2,4-dimethyl valeronitrile) (V70) and a liquid citrate-based biomaterial-ceramic composite of methacrylated poly(1,8 octamethylene citrate) (mPOC) and hydroxyapatite (HA) nanoparticles (mPOC-HA) that has improved handling and tissue compatibility characteristics. Our results show that: (a) these composites remain liquid until they are exposed to body temperature, which initiates polymerization to form a solid, tough material with desirable, modular compressive strengths comparable to trabecular bone; (b) the addition of HA decreases temperature generation below the threshold that leads to tissue necrosis; and (c) composites remain biocompatible in vitro and in vivo.

<p>The amount and type of waste are increasing due to population growth. Many harmful materials have been in the atmosphere for a very long times. This causes a crisis in the waste disposal and thereby contributes to environmental issues. Recycling concrete manufacturing waste materials not only offers a resource for producing concrete of top standard but also aids in correctly addressing the issue of waste disposal. Due to the leftover ceramic powder's high resistance and inability to be processed by any recycling process, using it in concrete is a good use for it. Using powdered ceramic waste in concrete as a pozzolana, their strength and water absorption were explored. The samples were made with 15% and 20% porcelain dust waste substitutes. Simultaneous effects were determined by using 0.5% and 1% nano-alumina and 15% and 20% waste ceramic powder. compression power, tests for water absorption, and weight and strength loss tests were accomplished. After 7 and 28 days of curing for nano-alumina at 0.5%, the increases in compressive strength are 11.46% and 10.22%, respectively. After 7 and 28 days of curing for 1% of the nano-alumina, the increases in compressive strength are 16.25% and 14.73%, respectively. The findings indicate that the compressive strength of the concrete is not significantly harmed by the inclusion of ceramic waste up to 20%. Additionally, the use of pozzolana, ceramic waste powder, and nano-alumina increases compressive strength while lowering the ability to absorb water. Consequently, nano-alumina can enhance the impacts of ceramic waste powder on concrete's characteristics.</p>
