The main objective of this research project is to determine the design of mixtures for a high initial strength concrete f'c = 210 kg/cm2, to optimize the commissioning time of a rigid pavement, in the City of Tarapoto. To achieve these results, research methodologies such as the quantitative type and correlational level have been used, in addition, an experimental - crosssectional and / or transectional - correlational research design was used, as well as the population, sample and procedure of analysis. data collection. Regarding the analysis of results, it was started from the verification of materials to be used, which were portland cement type I (Pacasmayo Cement), water (Ahuashiyacu river), coarse aggregate (crushed stone from the Huallaga river), fine aggregate (Cumbaza river). and additives (type F high-range superplasticizer and type C accelerating additive to achieve high early strength). Then the verification of design parameters was carried out, as well as the laboratory tests and mix design and finally the results of the concrete's compressive strength f'c=210 kg/cm2 evaluated at ages of 12 to 18 hours. 24 specimen samples distributed by mix design were made according to the water-cement ratio: RA/C= 0.32 (3 specimens for ages of 12 hours and 3 for ages of 18 hours), RA/C=0.30 (3 specimens for ages of 12 hours and 3 for ages of 18 hours), RA/C=0.28 (3 specimens for ages of 12 hours and 3 for ages of 18 hours), and the replica RA/C=0.28 (3 specimens for ages of 12 hours and 3 for ages 18 hours). at 12 hours and an average resistance of 376 kg/cm2 at 18 hours. The most favorable result (mix design with RA/C 0.28) was replicated, this in order to corroborate the results obtained initially, which yielded similar data, obtaining an average resistance of 332 kg/cm2 at 12 hours and an average resistance of 332 kg/cm2 at 18 hours. average resistance of 363 kg/cm2. Finally, the cost-benefit generated by this research project is that, if at the discretion of the designer it is necessary to save time and deadlines, it is convenient to work with any of the two designs with which favorable results have been obtained: R A/C 0.30 and 0.28, evaluating in detail the compressive strength values so that this structure can be put into service.
