Investigation practicing waste marble powder and lime powder as cement supplements in Self-compacting concrete (SCC) has obtained positive outcomes newly. In this research, waste marble powder (MW) and waste lime powder (LW) with the different combinations used in the design of SCC by replacement of cement 0, 10, 15 and 20%. In addition, 5% H2SO4 and 5% MgSO4 practiced for durability study and evaluate the effect of Sulfate attack and acid attack on filler content of mix after 28, 56, and 90 days curing of SCC sample. The results of the visual assessment and weight loss revealed that the increase in the amount of LW would enhance the performance of concrete, while the inclusion of LW and MW in SCC has shown positive results in terms of resistance against acid and sulfate attack. The mixtures with ternary binders of OPC, MW, and LW experienced the lowest strength loss after exposure to high concentrations of sulfate attack compared to unblended SCC.

“…There is not so much work performed in the area of dynamic elastic modulus that relates to concrete with and without chemical and mineral admixtures. The durability of concrete is defined as the ability of the concrete to resist weathering action, chemical attack, abrasion, or any other process of deterioration; that is, durable concrete will retain its original form, quality, and serviceability when exposed to its environment (Patel and Shah, 2016). The methods used to assess the durability of concrete include transport mechanisms such as sorptivity, porosity, water absorption, and sorption.…”

The use of superplasticizers is very uncommon in many developing countries. However, its inclusion in concrete enhances concrete's mechanical and durability properties. There is a yawning gap in the literature on the performance of Sulphonated Naphthalene Formaldehyde (SNF) superplasticizers in concrete, especially in the sub-Saharan construction industry where the quality of aggregates used in production is questionable. This study produced two batches of concrete produced with locally sourced pit sand, with characteristic strength of 30 MPa. One batch was without the SNF superplasticizer to serve as a control, whereas the other batch was made with the incorporation of the superplasticizer. The fresh properties of slump and air content and the hardened properties of compressive and flexural strength, elastic, and dynamic moduli were investigated. Further, durability indicators comprising sorption, water absorption, sorptivity, chloride penetration, electrical surface resistivity, and acid attack were investigated. The results of the study demonstrated that the incorporation of SNF superplasticizers in concrete resulted in improved workability and a reduction in ion mobility within the concrete. This was attributed to a decrease in the presence of interconnected pores, leading to notable enhancements in mechanical properties such as increased strength, as well as improvements in both elastic and dynamic moduli. Moreover, concrete containing SNF superplasticizer protects the concrete much better from acid attack than those without SNF superplasticizer. The study recommends the use of SNF superplasticizers in concrete for improved workability, reduced ion movement via fewer interconnected pores, and enhanced mechanical properties, potentially boosting overall durability.

“…Some studies try to create a laboratory environment to accelerate corrosion, such as the one carried out by [23] and [24], that studied the behaviour of mass concrete in a synthetic acid environment prepared in the laboratory by adding nitric and sulphuric acid. The study concluded that resistance values decreased mainly in samples with a lower pH (1.5) subjected to the acid for six months.…”
