Abstract
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.
Highlights
Economy, durability, and sustainability are a principal parameter in today's construction industry
For evaluating the resistance of self-compacting concrete (SCC) mixtures to the aggression of sulfuric acid, there are no such standards in the ASTM which solely devoted
It was remarked that the lime powder (LW) and marble powder (MW) fillers produce an active impact on the durability characteristics of blended SCC and made SCC stable and strong against acid and sulfate effect
Summary
Durability, and sustainability are a principal parameter in today's construction industry. In recent years many quite important studies about self-compacting concrete (SCC) executed. The dumping at the remote site, hilly, and town area is costly, as well as creates numerous challenges in the environment. To utilize these wastes as filler in the cement-based product is of prime importance for sustainability issues. This research work defines the principal properties that produce green concrete self-compacting and durable. The durability studies cover sulfate attack, acid attack, and weight loss test. The main intention of this research is to produce SCC mixes that are resistant to sulfate attack suitable for Indian temperature conditions compared with usual concrete. The performance of the degraded specimens was evaluated by measuring the weight loss, change in strength and visual assessment
