Sustainable Utilization of Agricultural Waste Ashes in Concrete through Experimental Evaluation of Rice Husk Ash and Sawdust Ash as Partial Cement Replacements
This study shows improved compressive strength using rice husk ash in concrete, suggesting a method for reducing emissions and enhancing mechanical performance.
Key Points
Compressive strength improved with rice husk ash up to a 10% replacement level, indicating effective utilization.
Results revealed that sawdust ash performed optimally at 5 to 10% replacement, demonstrating its potential benefits.
Concrete mixes were assessed for compressive, flexural, and split tensile strengths after 7 and 28 days curing.
Limited incorporation of agricultural waste ashes can enhance sustainability in modern construction, suggesting practical applications.
