Municipal Solid Waste (MSW) management is a worldwide problem growing proportionally the earth human population. The practice of incinerating garbage has ceased in some parts of the world because of air contamination and other public health issues. Environmental impact of landfilling is ever increasing. There is clearly a need to adopt cost-effective alternatives to treat MSW. This paper is a part of a major work that considers MSW based biomass as a partial replacement of sand in concrete. The product is an exciting and ecofriendly alternative for the building industry. Here, in this paper, compressive and flexural tests are conducted on samples containing 5%, 10% and 15% replacement of sand by biomass. Results are presented and discussed in a view to include biomass in concrete intended for certain type applications in the construction industry such as temporary works.

“…At ambient temperature, the hydration process takes places in NC to produce ettringite as a bonding between the concrete particles (Thomas, 2007;Scrivener et al, 2015). However, the utilization of byproducts in concrete mix can increase the production of calcium silicate hydrate and calcium hydroxide containing ettringite because of second-phase hydration process (pozzolanic reaction) (Saha, 2018;George and Sofi, 2017;Fauzi et al, 2016). Second phase of hydration process occurs because of higher silicate (SiO 2 ) in the by-product such as FA, silica fume and rice husk ash (RHA) compared to OPC.…”

Purpose Concrete-filled steel hollow (CFHS) column is an innovation to improve the performance of concrete or steel column. It is believed to have high compressive strength, good plasticity and is excellent for seismic and fire performance as compared to hollow steel column without a filler. Design/methodology/approach Experimental and numerical investigation has been carried out to study the performance of CFHS having different concrete in-fill and shape of steel tube. Findings In this paper, an extensive review of experiment performed on CFHS columns at elevated temperature is presented in different types of concrete as filling material. There are three different types of concrete filling used by the researchers, such as normal concrete (NC), reinforced concrete and pozzolanic-fly ash concrete (FC). A number of studies have conducted experimental investigation on the performance of NC casted using recycled aggregate at elevated temperature. The research gap and the recommendations are also proposed. This review will provide basic information on an innovation on steel column by application of in-filled materials. Research limitations/implications Design guideline is not considered in this paper. Practical implications Fire resistance is an important issue in the structural fire design. This can be a guideline to define the performance of the CFHS with different type of concrete filler at various exposures. Social implications Utilization of waste fly ash reduces usage of conventional cement (ordinary Portland cement) in concrete production and enhances its performance at elevated temperature. The new innovation in CFHS columns with FC can reduce the cost of concrete production and at the same time mitigate the environmental issue caused by waste material by minimizing the disposal area. Originality/value Review on the different types of concrete filler in the CFHS column. The research gap and the recommendations are also proposed.
