Abstract :
Natural Resources in this world are being consumed in a rapid pace especially in the application of Civil Engineering where most of the structures are made with cement and concrete. It is notable that within the production of those materials, emits many harmful emissions which will disturb human life and the ecosystem. This study intends to reduce the environmental impact of cement and concrete, by substituting waste tire to fossil fuels and substituting crumb rubber to fine aggregates. Previous research has proven the possibility of using these specific materials as partial substitute to its original processes. Life Cycle Assessment (LCA) of utilizing waste tires in the production of cement and concrete was assessed. SimaPro was utilized to quantify the environmental impact analyzing a one (1) kilogram of cement and one cubic meter of concrete. For the midpoint analysis of cement, it only showed a small difference but further analyzing it was discovered that substituting 30% waste tires to fossil fuel by weight will reduce the emissions of fossil fuel alone by 20%. The reduction of emissions of fine aggregates was directly proportional to the amount of substitution. In conclusion, the utilization of waste tires and crumb rubber did not cause any more harm to the environment and will also lessen the usage of natural resources.
