Abstract
The objective of this study was to analyze the addition of plastic as a partial component of the coarse aggregate in concrete, for the design of ecological blocks, establishing a linear equation that estimates the compressive strength of the block, varying the volumes of cement, sand, gravel and plastic. For the design of blocks, volume in three proportions were considered (cement/fine aggregate/coarse aggregate), thus four types of mix proportions were made (1/1/1, 1/1.25/2.5, 1/1.5/3 and 1/2/4). Coarse stone aggregate as a partial aggregate component was replaced by flake HDPE type plastic HDPE in proportions of 0, 25 and 50% coarse stone replacement. The compressive strength and unit weight of the concrete was measured after 30 days of curing. The research methodology was of a quantitative type of descriptive experimental design. The results showed that the addition of 25 and 50% plastic as a coarse aggregate reduced the unit weight of the concrete to 9.7 and 12.02% respectively. However, in this case, the reduction in compressive strength was up to 29.17 and 48.5% respectively for its best effectiveness, reducing only the unit weight of the parts.
