Abstract
Purpose
In the construction sector, river sand has turned into a costly material due to various reasons. In the current study, used foundry sand (UFS) and spent garnet sand (SGS) are used as a partial and full replacement to sand in concrete production.
Design/methodology/approach
The objective of the work is to develop non-conventional concrete by replacing river sand with a combination of UFS (constant 20Wt.% replacement) and SGS at various percentages (20, 40, 60 and 80 Wt.%).
Findings
Compared to conventional concrete, the 28 days compressive strength of non-conventional concrete (with UFS at 20% and spent garnet sand at 20%, 40% and 60% were 8.12%, 6.77% and 0.83% higher, respectively. The 28 days split tensile strength of non-conventional concrete (UFS at 20% and SGS at 20 and 40%) were 32.2% and 51.6% higher, respectively.
Research limitations/implications
It can be concluded that 60 Wt.% of river sand can be combined replaced with 20 Wt.% UFS and 40 Wt.% SGS to produce good quality concrete whose properties are on par with conventional concrete.
Practical implications
The results showed that combined SGS and UFS can be used as a partial replacement of river sand in the manufacturing of concrete that is used in all the applications of construction sector such as buildings, bridges, dams, etc. and non-structural applications such as drainpipes, kerbs, etc.
Social implications
Disposal of industrial by-product wastes such as SGS and UFS affects the environment. A sincere attempt is made to use the same as partial replacement of river sand.
Originality/value
Based on the literature study, no work is carried out in replacing the river sand combined with SGS and UFS in concrete.
