Preparation of concrete that minimizes the impact on the environment, using used tires from light and heavy vehicles in the province of Santa Elena

Abstract

Waste from rubbers tires are considered to be an environmental and sanitary risk worldwide. As an example in Ecuador, every year nearly 2.4 million rubber tires of various types are discarded as trash, which is equivalent to 55000 tons, according to the Proactive Corporation for Investment Promotion (INVEC). A small porcentage of the waste, are reused to be re-rubberized. But the majority is incinerate or deposited in dumping grounds open to the environment, which is a huge risk to the environment and the health of individuals. The project seeks to create a design of concrete including particles of rubber from discarded tires. The tires will undergo a rigorous selection process, a controlled threading process, and a fabrication according to the specifications of the international standards of concrete of the American Concrete Institute (ACI) and the Construction Ecuatorian Standards (NEC), and based on these specifications, the goal is to obtain an acceptable concrete apt to be used in low traffic streets, sidewalks, pedestrian zones, and other concrete structures, minimizing the environmental impact to the misuse of tires in the province of Santa Elena.
