Análisis de la resistencia a compresión del concreto con reemplazo parcial del cemento por osamentas de animales calcinadas y pulverizadas.

Abstract

The purpose of this research work is to poblicize the mechanical behavior of concrete specimens, adding cacined bone ash in the dosaje as a partial replacement of GU-type hydraulic cement in different percentages, for a compressive strength of 24 MPa in 28 days, for the purpose of comparing the results of simple sylinder compression whit a standard dosage and the dosage of concrete whit replacement of calcined ash at (600, 900, 1200) °C and different percentages (10, 12.51 15) % for each of the temperatures. The purpose of this study is to mitigate the environmental impact caused by this type of waste (animal bones), the obtaining of the raw material was mainly from the meat and shrimp markets where they fish, which therefore there is greater waste. The experimental part occurs first in the calcination of the bone at different temperatures in order to eliminate the organic matther that can alter the behavior of concrete, it is crushed and sprayed mechanically and manually to pass it through sieve No. 200 and can have the appropiate density for the replacement of cement, a total of 30 specimens were elaborated, 3 of standard dosing, 9 for a temperatura of 600 °C, 9 to 900 °C and 9 to 1200 °C. The results are base don the comparison of the compressive strength between the specimens according to the percentage of replacement, temperature with known standard resistance, in addition, an economic análisis is carried out to determine whether or not it is favorable to incorporate the raw material in the field of construction.
