Análisis del proceso de hidratación del cemento de una marca de cemento ecuatoriana: cemento de alta resistencia inicial.

Abstract

The purpose of this work is to analyze the components present in high initial strength cement at different ages, as well as its compressive strength in cubes and cylinders and x-ray diffraction analysis. For this purpose, mortar compounds were evaluated with their respective standards to analyze the performance of each compound and determine their performance parameters. The parameters will be used to achieve an efficient dosage and to check the strength of the cement. The physical properties analyzed were developed and evaluated with density tests, the elaboration of mortar cubes evaluated in compression at 1, 3, 7 and 28 days and the elaboration of concrete cylinders for the determination of compression and traction. For the chemical properties, an x-ray diffraction test was conducted on mortar powders at the ages mentioned above. From the results of the physical tests, the hardening curve of the concrete can be identified, and from the Chemical test, the presence of Ettringite, Portlandite and Tobermorite in the cement can be evidenced.
