Abstract

The present research work is based on analyzing the results of the influence of sugarcane bagasse ash (CBCA), a natural polymer ash, on concrete with f'c=210 kg/cm2, made with aggregates. from the Pampa Azul quarry, in order to analyze and compare the results of compressive strength in different percentages of CBCA addition (2%, 4% and 7%). Likewise, the physical characteristics of the aggregates were determined according to the ASTM C 136 / NTP 400.012 standard, to then carry out the mix design according to the ACI Committee 211.1. The mixture design of the pattern concrete and concrete was carried out, adding the percentages of CBCA (2%, 4% and 7%), of which 36 specimens of 100 mm x 200 mm were prepared (ASTM C 192 / NTP 339.183). , prepared in the laboratory of the Universidad Privada del Norte, which were compression tests (ASTM C 39 - 18 / NTP 339.034) at 7, 14 and 28 days of curing, obtaining with 2% CBCA a resistance of 233.5 kg/cm2, representing an increase of 1.83%; with 4% CBCA a resistance of 245.9 kg/cm2, representing an increase of 4.03% and with 7% CBCA a resistance of 264.5 kg/cm2, representing an increase of 12.02% compared to the standard concrete. From the results obtained, it is concluded that the addition of CBCA in the concrete is very favorable in the percentages of 4% and 7%, obtaining greater results compared to the standard concrete.
