Incorporation of Silica Fumes and Waste Glass Powder on Concrete Properties Containing Crumb Rubber as a Partial Replacement of Fine Aggregates

Waste management is the first priority for many countries, so focus of this research on using waste materials in concrete as fillers and substituting ingredients such crumb rubber (CR) fine aggregates. The utilization has gained attention recently, but CR substitution results a reduction mechanical durability properties due to weak bonding lower stiffness CR. To overcome issue, addition strength-increasing cement substitutes investigated along with (5%, 10%, 15%) aggregates tested behavior concrete. Constant 10% glass powder (WGP) silica fume (SF) were substituted separate mixes. main goal study investigate suitable proportion from SF WGP enhancing rubberized concrete’s evaluate materials’ uses considering various parameters. compared both used well control workability, compressive strength, tensile density, ultrasonic pulse velocity, dynamic modulus elasticity. elasticity was observed incorporation CR, also an increase these fumes cement. It that enhanced better WGP. 5% strength without by 11%. Similarly, 6%.
