Waste foundation sand (WFS) is one of the most abundant residues in the foundation industry. Currently, its annual production is estimated to be three million tons. This material has properties that make it an attractive candidate for implantation as an alternative constituent to a natural fine aggregate in concrete applications. This application can promote greater sustainability, as it would establish a noble destination for the waste generated in large quantities by the metallurgical industry in addition to reducing the exploitation of a natural resource widely used by the civil construction industry. Given this, the present study observed the test of three different proportions of replacement, 25, 50, and 100% by mass, of natural sand by WFS in concrete. To assess the feasibility of these replacements, several tests were carried out covering mechanical properties and aspects related to the durability of concrete. The results indicated a significant improvement in the mechanical performance, with a resistance gain of 25% in relation to the reference concrete. As for the modulus of elasticity, there was no significant variation. As for aspects related to durability, both the absorption test and the alkali aggregate reaction test did not show statistically significant disparity, which attests to the technical feasibility of using nonconcrete WFS.

Concrete that is self-compacting or self-consolidating is referred to as SCC with unique properties such as flowability, self-consolidation, and workability and it can be placed in any type of Reinforced cement concrete (RCC) work where reinforcements are congested and not able to do compaction. In this fast-moving modern era, the role of SCC is unavoidable. It is an advanced method of concreting and sustainable materials that can be utilized as an alternative to river sand or crushed stone sand which includes waste foundry sand, steel slag, stainless steel slag, and iron slag, among others. These materials are the product of industries and create dumping problems in the environment. These materials have a similar composition to fine aggregate there for can be replaced by some percentage with fine aggregate. To bring an alternative to existing river sand and to prevent sand mining In this novel paper detailed investigation has been made to review different sustainable material as fine aggregate and a critical review is done about the SCC features (fresh and hardened) produced using waste foundry sand, steel slag, stainless steel slag and iron slag respectively. In addition, mechanical properties along with microstructure studies of different sustainable fine aggregates are discussed. The optimum substitution rate for sustainable fine aggregate and its benefits are studied. All the alternative fine aggregate has made a significant impact on fresh and hardened properties. Due to their unique performance, various fine aggregates notably waste foundry sand, steel slag, stainless steel slag and iron slag can be employed in making SCC.

“…Martins, et al [30] used FS as a partial substitute (10%, 20%, 30%, 40%) for natural sand in selfcompacting concrete. Parashar, et al, 2020 [31], investigated the usability of waste foundry sand in self-compacting concrete (SCC) and reported that WFS is suitable up to a certain extent for the replacement of fine aggregate in concrete.…”

Methanol synthesis catalyst (MSC) waste was applied as the principal component (till 70 wt.%) of sustainable ceramics in composites with bauxite processing waste (RM), and waste foundry sand (FS). The results of the initial components' chemical interaction studies by a complex of methods (XRD, SEM/EDS/mapping, AAS and LAMMA) during heating demonstrated the synthesis of amorphous glasslike new formation, their filling of pores and compaction of the ceramic’s structure. In this case, a strong chemical and mechanical binding of all heavy metals and other hazardous elements of the initial industrial waste occurs with their transfer to an insoluble in an acidic environment. The materials with the highest MSC contents have the highest axial resistance values ill 25.98 MPa after firing at 1050°C.
