The need for maintaining the living environment is increasing as the economy grows and the quality of life rises. Attempting to render buildings "green" to the environment from the standpoint of civil engineering is a hot and challenging task now. The construction industry uses lightweight foamed concrete (LWFC) as a flexible building material. Contrarily, LWFC has a variety of flaws including stiffness, poor toughness, substantial porosity, crucial drying shrinkage, and minimal resistance to cracking and deformation. Although it’s a sustainable solution, continuous research strives to enhance its sustainability and mechanical capabilities. Nanoparticles have excellent mechanical, thermal, and electrical capabilities that have inspired the creation of new nanocomposites with exceptional and multipurpose features. Titanium dioxide nanoparticles (TNP) have a much larger specific surface area because of nanostructures' exceptional properties. The large increase in nanoparticles will boost the role of concrete strength by improving the microstructure of the material. There is significant uncertainty regarding the process by which TNP might change the strength characteristics of LFC because the influence of TNP in LWFC was not previously explored. To better understand how TNP affects the slump flow, compressive, splitting tensile, and bending LWFC of 980 kg/m3 density, this study will look at its effects. Six TNP weight fractions were taken into consideration: 0% (control), 1%, 2%, 3%, 4%, and 5%. Slump flow, electrical resistivity, compressive, splitting, tensile, and bending strengths were the variables investigated. In addition, the relationship between strength parameters was found. The results showed that the highest compressive, bending, and splitting tensile strengths resulted from a weight fraction of TNP of 3%.

“…Considering their notable advancements in durability and their potential to foster a more ecologically conscious environment, green composite materials have garnered considerable interest as a viable avenue for the advancement of superior construction materials. In view of the ubiquity and economical nature of commercial and natural pozzolans, as well as accelerator materials, there remains a growing emphasis on waste materials to champion environmental sustainability [36][37][38][39][40].…”

The incorporation of materials derived from industrial waste presents a viable avenue for mitigating the exorbitant production expenses associated with building materials, while concurrently ameliorating the deleterious ecological ramifications of said waste. The utilization of pulverized fuel ash (PFA), an industrial residue resulting from the combustion of powdered coal in an electricity-generating facility, as a substitute for cement in the composition of concrete, is a viable option owing to its inherent pozzolanic properties. The present study endeavours to investigate the potential of Partially-Fumed Ash (PFA) as a viable substitute for cement in the production of foamed concrete (FC). The thermal and transport properties were meticulously assessed, with a particular focus on thermal conductivity, thermal diffusivity, specific heat capacity, water absorption, and porosity. A series of experiments have been undertaken wherein varying proportions of Portland Pozzolan Cement have been substituted for PFA, specifically at levels of 10%, 20%, 30%, 40%, and 50% by weight. The findings suggest a prospective application of PFA in the manufacturing of FC. The utilization of PFA (Pulverised Fuel Ash) assumes a pivotal role in enhancing the thermal conductivity, thermal diffusivity, specific heat capacity, water absorption, and porosity of FC. Therefore, it can be inferred that the utilization of PFA holds promising potential in the production of cost-effective, lightweight construction materials, while simultaneously mitigating the adverse environmental consequences.
