Incidence of Tara Ash on the Physical-Mechanical Properties of Concrete F'c = 350 Kg/Cm²

Abstract

The present research work entitled "Incidence of tare ash on the physical-mechanical properties of concrete f'c = 350 kg/cm2" proposed a general objective to determine the incidence of the incorporation of tare ash on the physical-mechanical properties of concrete f'c = 350 kg/cm2. The methodology belongs to the applied type with a quasi-experimental design. The sample was census and consisted of 12 molds called Abrahams Cones; for the slump, 12 cylindrical molds; for the unit weight test, 72 cylindrical specimens; of which 36 were for the compression test and 36, for the diametral traction, of concrete f'c=350 kg/cm2 with replacement of tare ash in percentages of 0%, 6%, 12% and 16%, with respect to the cement. Tests were carried out to determine the physical and mechanical properties of the concrete in the 4 designs. The results indicated that the optimum amount of tare ash was 6%, presenting a slump of 3.47", a unit weight of 2.29 kg/cm3, a compressive strength of 502.70 kg/cm2, and a tensile strength of 37.18 kg/cm2. Thus, it was concluded that the incorporation of tara ash has a favorable effect on the physical-mechanical properties of concrete f'c= 350 kg/cm2.
