In a hydraulic pavement, the rupture module is the main parameter that gives
us information about its mechanical resistance to the loads to which it is
subjected, nevertheless, the abrasion resistance of the same is another
fundamental parameter that intervenes directly in its performance and is
proportional to its useful life, as this resistance is greater, so will its useful
life. For experimental development, and worried about the high consumption of
Portland cement worldwide, a mixture of hydraulic concrete was developed,
replacing 10% with respect to the mass of the cement by sugarcane bagasse ash
previously pulverized, in which was observed that about 90% of his particles had
a size smaller than 75 μm (N° 200, Tyler Mesh Size). The performance of said
concrete mixture was compared with that of a concrete witness with water /
cement ratio (a / c) = 0.42, using a CPC-30R-RS cement. In addition, a 0.74%
fluidizing additive was added (CRISOTAN-R5) with respect to the cement mass to
increase the workability of the mixture, which is reduced with the incorporation
of sugarcane bagasse ash, this attributed to the porous structure of its
particles. The determination of the resistance to abrasion was carried out by the
Cántabro test, using cylindrical specimens sectioned in 3 thirds for the analysis
of each of them, at the age of 230 days, they which remained immersed in water
during the mentioned time. The concrete with sugarcane bagasse ash
presented a greater resistance to wear by abrasion in the upper third, middle
third and lower third, respectively, while the witness concrete showed a greater
resistance to wear by abrasion in the middle third, lower third and upper third,
respectively. Analyzing both mixtures it was determined that the witness
concrete presented a better performance.
