Abstract
The construction industry undeniably contributes to the CO2 emission to the earth due to the time-consuming process and high energy needed. Steel, concrete, iron, glass and plastic material are commonly used in the construction site so as the waste can be seen around. Construction waste treatment is potentially reused for another construction product due to its good material properties. Rebar tie wire is one of the beneficial construction wastes besides steel due to its remarkable compressive and tensile properties. Utilization of rebar tie wire addition for enhancing the mechanical properties of a paving block will be the focus of this paper. The tensile strength of rebar tie wire was recorded up to 173 MPa which is strongly possible to increase the mechanical properties of the paving block. The percentage of the rebar tie wire addition was limited until 3.5% to the weight of cement. The water-cement ratio of the paving block mixture was locked to 0.3, other than that the proportion of cement to sand was 1 to 2.5. The target of A type of paving block based on SNI 03-0691-1996 was reached by the addition of rebar tie wire between 2% and 3.5% which best compressive strength of 46.67 MPa resulted from 3% of addition. Moreover, the abrasion and absorption test showed the same good result as the quality of compressive strength.
