In the present work the incidence of C. odorata L. aggregate extract in the mixing water was evaluated as an alternative to improve the compressive strength of concrete and the workability of the mix, following NTC 673 and NTC 396 standards. For the analysis of compressive strength and workability of concrete mixes two variables were involved which were water/cement ratios of 0.55 and 0.60 and dosages of cedar extract by weight of cement added in the mixing water of 0.0, 0.3, 0. 5, 0.7 and 0.9 %, resulting in a total of 30 cylindrical specimens of 4 inches in diameter and 8 inches in height manufactured under a 1:2:2 ratio, with coarse aggregate of maximum size of ¾ inches and type I cement for general use, in accordance with NTC 550. Describe the main results and indicate the exact level of statistical significance. Highlight those results achieved that are novel. The use of cedar exudate is recommended to improve the workability and compressive strength of concrete.
