Sustainable construction is a rapidly growing area of research focused on using industrial waste to replace Portland cement in concrete. This approach not only reduces CO 2 emissions from cement production but also serves as an effective way to diminish the environmental impact of concrete production. This study aims to investigate the …
Fly ash and bottom ash are byproducts created during the burning of coal for energy production. ... These particles settle at the bottom of the boiler and are collected by a sluice system. Bottom ash typically consists of sand, gravel, and other minerals. ... It can be used as a more cost-effective replacement for cement in concrete which ...
1.2 Density. In terms of density, the higher the content of bottom ash in concrete, the lower the density. It was due to bottom ash having a lower specific gravity that gives lower weight per cubic meter of the concrete as a replacement of sand was by volume (Singh & Siddique, 2014a; Andrade et al., 2009; Singh & Siddique, 2016). 1.3 …
A common material used to replace OPC is fly ash (FA), a coal power plant byproduct that has high silica, alumina and iron oxide content. Coal bottom ash (CBA) is an underutilized byproduct from power plants that is commonly used as a river sand substitute.
Rafieizonooz et al. (2016) investigated the coal bottom ash and fly ash in concrete as replacement for sand and cement. It was seen that flexural and splitting tensile strengths of the experimental mix containing 75% bottom ash and 20% fly ash exceeded much more than the control sample. ... on fresh and hardened properties of concrete …
The effect of fly ash substance and substitution of trampled sand stone total with concrete squandrs and marble squanders employed ... 1.42 : 3.3. Controlled concrete of M 20 grade was made with 0% replacement of fly ash, bottom ash, and light expanded clay aggregate (LECA) in each mix and their compressive strength and split tensile …
Normally, the compressive strength values of fly ash based GPC is 5–7% higher than those of OPC, the similar values could be attributed to the addition of bottom ash and its replacement with fly ash itself. The larger particle size of bottom ash will have some effect on the densification of the matrix and consequently, the loss of ...
