“…Experimental analysis is done with reference to fresh and mechanical properties of SCC such as flowing ability, passing ability using IS 1199:2019 and compressive strength using IS 456:2000 (Reaffirmed in 2021). In this study, the slum flow test was conducted for flowability and segregation of SCC, L-box test for passing ability of SCC and compressive strength of M30 SCC measured in a compression test machine at 7 and 28 days of curing period with ratios of 0%, 10%, 15%, 20%, 25% and 30% pond ash for fine aggregate replacement [10].…”

“…Fly ash is a major pozzolanic material commonly used for replacing the cement partially in the concrete. Pond ash is a combination of fly ash and bottom ash; thus, pond ash will also have little pozzolanic property so, can be used as a filler material [8][2] [9] [10]. Available pond ash may not be suitable to use directly as a partial replacement of sand or cement, some modifications are needed to change some physical properties like particle size [1].…”

A rapid industrialization and urbanization resulted in the increased demand for usage of electricity at an alarming rate. At the same time, coal ashes are produced in coal based thermal power plant in large quantity. Fly ash is being used as an alternative material in construction industries while pond ash is disposed-off on huge land areas resulting in environmental pollution through soil, water and air. This research emphases on the study of performance of pond ash as a fine aggregate in self-compacting concrete (SCC). Fine aggregate is substituted by pond ash in percentages of 10, 15, 20, 25, 30. The fresh state properties of SCC like flowability, passing ability of all mixes have been checked by conducting inverted slump cone and L-box according to IS code of practice. The cost analysis of SCC has been conducted to establish the relative cost savings. From the experimental investigation, cost analysis and life cycle assessment, it is concluded that SCC with 20% fine aggregate replaced by pond ash can be economical and environment friendly self-compacting concrete.

“…Reference [11] studied the compressive and flexural strength of the mortar made with the coal-based pond ash as a sand replacement of 0% to 100% which collected from the Bhusawal thermal power plant in India. They concluded that the coal-based pond ash is able to increase in the amount of CSH gel and strength is more practical when replaced the sand with 40% in cement mortar.…”

Bottom ash (BA) is a waste material which found from the electrical power plant whether collect from a boiler or landfill area. While, mortar is a construction material which incorporated between sand, cement and water. There are a lot of problems such as environmental impact and limited sources of raw material which able to solve by using waste material as a sand replacement in mortar. Thus, BA is selected and treated with fully submerging in the water to recognise as washed BA. The process is used for minimised the carbon content of the BA. Washed BA is utilised in a mortar with 5%, 10%, 15%, 20% and 25% of sand replacement and compared the result with control mix (0%) of sand replacement. The mortar design mix proportion is depended on cement to sand ratio of 1:3 with 0.55 of water-cement ratio. There are two testings, workability for fresh condition and compressive strength for hardening condition of the mortar is done. As a result, the height of the slump is reduced with increasing of the sand replacement in mortar. Additionally, the maximum load and compressive strength of the mortar is also decreased when the washed BA as a sand replacement added. Lastly, the specimen with 15% of sand replacement of washed BA is the best mortar mix which provided reasonable compressive strength and workability for further study.

“…In addition, waste date palm trees can be polluting to the environment when they undergo decomposition with time. As such, it is interesting to explore the viability of using these materials to optimize the performance of mortar cubes from their engineering aspects [12]. The strength performance of cement-sand mortar cubes enhanced with various types of ashes and fibers are reviewed under this section.…”

The problem of conventional cement mortar cubes is the requirement of cement to be used for their production. It is recognized that cement production involves a significant release of carbon dioxide to the atmosphere, which is detrimental to the quality of the environment. To adopt a sustainable development of building materials, date palm tree has been used by numerous researchers to partially replace the cement in the production of mortar cubes. The study aims: 1. To optimize the engineering properties of cement mortar cubes enhanced with date palm fibers and leaves ash. 2. To investigate the microstructures and chemical characteristics of the optimized cement mortar enhanced with waste date palm fibers and leaves ash. The design optimization in this study, mortar cubes were formulated in such a way that the trial mix designs were varied with date palm leaves ash (1% to 10% date palm leaves ash as partial substitute of cement) and date palm, fibers (1% to 5% as partial substitute of silica sand). The mechanism of reaction at early- and long characterization tests studied term period of curing on paste, including water absorption test, Ultrasonic Pulse Velocity (UPV) test, compression test, SEM test, energy dispersive X-ray (EDX) test, X-ray and Fluorescence tests (XRF). As the study's major finding, it was realized that the optimal mix ratio of the treated mortar cubes was noticed to have 4% date palm leaves ash as partial cement substitute and 2% date palm fibers as partial silica sand substitute. There was significant improvement in the treated mortar cubes' engineering properties compared to those of the control mortar cubes. The study outcomes proved that both date palm leaves ash and fibers can cause pozzolanic activity and reinforcing effect on the treated mortar cubes.
