“…It is evident from the pattern of the cracks at tension face (bottom side) of the slab (Figure 6) that the failure of SCR8 slab occurred due to diagonal tension cracks. This is in agreement with the findings of Mali and Datta (2018) The BRC8 specimen containing 8 mm × 8 mm bamboo strips in the two principal directions underwent the failure mode same as that of the control SRC8 specimen. This can be stated by viewing the pattern of cracking (Figure 7) as it is almost same for both.…”

“…While selecting bamboo culm, it is ensured that the overall geometry is sufficiently straight and free from fungus or damage, to allow the final samples to reflect well-distributed fibers. This exercise helped the selection of good samples with good physical and mechanical properties (Mali & Datta 2018;Sharma et al 2015a).…”

“…Currently, more than 1,200 species of bamboo have been discovered worldwide (Sharma et al 2015b). Environmental factors like location, water, climate, and type of soil determine the availability of different species of bamboo (Mali & Datta 2018). Intriguingly, the regions near the developing states of the world are rich in bamboo and so is the case of small villages of these states.…”

“…Several researchers have investigated the utilization of bamboo strip as the main material in reinforcing slab panels (Bhonde et al 2014;Chithambaram & Kumar 2017;Kankam & Odum-Ewuakye 2006, 2001Wibowo et al 2017). Mali and Datta (2018) have examined the bamboo reinforced concrete slab panels and found that these BRC structural components can be used in low-cost housing, especially as a component of roofing in the case of limited gravity loading. In comparison to traditionally used RC slabs, they are environment friendly and inexpensive.…”

Reinforced concrete is perhaps the most widely used building material in the world. However, the materials used for reinforcement of concrete i.e. steel is quite expensive and scarcely available in the developing world. As a result, bamboo is considered to be a cheaper replacement with high tensile strength. This research investigated the structural behaviour of bamboo-reinforced concrete slabs used for footplate foundation subjected to concentrated load. For this purpose, four different reinforced concrete slab panels were developed and analyzed. The influence of replacing steel with bamboo for the reinforcement of concrete slabs on their structural behaviour was assessed by determining the load-deflection characteristics, the ultimate load, the stiffness, the ductility, the cracking pattern, and the energy absorption capacity. The results showed that in comparison to steel reinforced concrete slabs, the strength of 82% can be acquired by the bamboo reinforced slabs. Furthermore, ductility demonstrated by the two types of specimens was almost equivalent i.e. up to 93%. Those indicated that the structural behaviour demonstrated by bamboo reinforced slabs is quite comparable to that of steel reinforced concrete slabs. Therefore, bamboo can prove to be a promising substitute for steel in concrete reinforcement. Future studies may further examine this opportunity.

“…The industrial byproducts such as fly ash, GGBFS, metakaolin and RHA etc. are used in civil structural application, in which some of them are utilized and remaining are disposed into the land [11]. This would create major problems such as air pollution, ground water pollution and land pollution.…”

This research work presents the overview of geopolymer mortar application into the ferro cement panel with the incorporation of crumb rubber and Nano fly ash. The geopolymer mortar is prepared by using industrial wastes as a base material such as fly ash and ground granulated blast furnace slag (GGBFS) which generally helps to reduce the level of CO2 emission. Also, the recycled tyre crumb rubber is utilized as a sustainable innovative construction material which is used a partial substitution for sand upto 5% for enhancing the ductility without any strength degradation. These reduces land fill problems and ground water quality degradation problems. Crumb rubber has the ideal capacity to absorb energy from static and other kind of loads. The geopolymer binder preparation is done by utilizing material such as fly ash, GGBFS, alkaline liquid made of NaOH and Na2SiO3 , Nano fly ash. The Nano fly ash is used as an additive which helps in increasing the strength and durability of the element by its pore filling capability. This project aims to enhance the strength of fly ash based geopolymer mortar with the help of GGBFS incorporation. The molarity of alkaline activator, solution to binder ratio and silicate to hydroxide ratio is fixed as 12, 0.4 and 1.5 throughout the process. The mortar cubes and panels were heat cured under hot air oven at 80ᵒ C for 48 hours. The mechanical behavior of geopolymer mortar is assessed by compressive strength test water absorption test. The panel is made of high strength geopolymer mortar and expanded metal mesh with chicken mesh for obtaining higher energy absorption capacity with good deforming ability and less crack pronouncement. The investigation involves finding the initial crack load, ultimate failure load and residual flexural strength ratio. The results show that the tyre inclusion enhances the flexural strength of the ferro geopolymer panel by means of its ductile enhancing capacity
