“…The pores in the structure of aggregate (i.e., LECA) are the primary cause of a decrease in the density of geopolymer mortar. 31 Moreover, a marginal decline in dry density values can be seen by increasing the age of the LWGM from 1 to 28 days. For the 80%EC sample, there was a 3.7% reduction in its dry density at 28 days compared with that at day one.…”

This research provides an experimental investigation on the properties of fiber reinforced composite materials consisting of lightweight expanded clay aggregates (LECA) and polyvinyl alcohol (PVA) fibers. The influence of temperature (room temperature, 250°C, and 500°C) on the lightweight geopolymer mortar (LWGM) composite materials is also explored. LECA is used as a partial replacement to river sand with 60% and 80%. The base material utilized for LWGM is slag activated by a mixture of sodium silicate and sodium hydroxide solutions. The fresh properties in terms of workability and density were performed. A series of experiments, such as compression, flexural and uniaxial tensile strength tests, were executed to assess the mechanical properties of LWGM composite materials. In addition, the microscopic variations due to the elevated temperature were also evaluated by scanning electron microscopy (SEM) to understand the macro-scale behavior of the samples. The results indicated that increasing the level of LECA replacement caused a reduction in the density and compressive strength of the LWGM. Also, incorporating a 1% PVA fiber volume fraction significantly enhanced the flexural and uniaxial tensile behavior of LWGM composite materials. The compressive strength enhancements were observed at 250°C due to further geopolymerization, while compressive strength reductions were obtained at 500°C due to the vapor impact and difference in thermal expansion. In addition, the load-carrying capacity of all samples increased, and displacement capacity decreased under flexural tests at 250°C. However, the ductile behavior of the PVA incorporating specimens changed to brittle due to the melting of PVA fibers.

“…Compared to other thin construction materials, ferrocement has sufficient strength, hardness, lightness, and durability 2,4–7 . Studies on ferrocement have revealed significant improvements in the service and ultimate tensile crack behaviour of composite structures 8–13 . The components of ferrocement are also readily available, and structural products can be built without the need for highly experienced labour, making it a time‐ and money‐efficient technique.…”

In this fast‐developing world both in the form of trends and population. House is a basic need for everyone and it is always preferred to be completed within a minimum time. Ferrocement wall panels will be a great advantage it accommodate quicker construction. It also helps the building to be built with required shape and size and also with a better aesthetic appearance. Other advantages include less cost and also provide better insulation for soundproofing. Because of their ease of replace ability, they can be assembled into an appropriate framework. They can be restructured anywhere at any time, so it is a better substitute than any other kinds of walls. In this investigation, the structural behaviour of ferrocement wall panels of size 2.5 and 3 m in length, 1 m width with 30 mm thickness has been casted with and without addition of nanosilica which obtained from Zea mays was investigated. Amorphous nanosilica has been extracted from Zea mays plant by a series of process like separating the parts of the Zea mays plant, washing the parts to remove dirt, acid wash, drying, calcination, sol–gel adjustment and then post filtration pre, post filtration, which include corrosive pre‐treatment by acid wash, draining, sol–gel adjustment and drying in hot air oven have been used in this work, which will enhance the mechanical properties of ferrocement. ANSYS Software was used to create finite element models to analyse the behaviour of the wall panel from static response to failure. Finally, the experimental and numerical model comparisons were presented and evaluated.
