ABSTRACT
The objective of this work is to identify the behavior of some traces of concrete in which there is the partial replacement of the natural sand by the landfill ash. Four traces were proposed, the first one with 100% natural sand, which will be used as reference traces, the second with 5% ash from the landfill, in relation to the natural sand mass, the third with 10% ash, the room with 15% ash. The traces of the concretes were composed of cement, sand / ash, gravel and water, and these were tested for their compressive strength. The results showed that the composite traces with ash showed good performance with respect to the compressive strength. The relevance of this study is due to the fact that landfills, when used the process of burning the garbage, produce ashes, causing an impact on nature that generates an important environmental liability. Therefore, the use of this type of waste makes it possible to reduce this environmental impact.
