Efecto del proceso de fraguado de cementos que se distribuyen en ecuador y cómo influyen en su calidad

Abstract

In the present bibliographic research, the effect of setting in cements distributed in Ecuador and how this property influences its quality was analyzed. The setting is the mixture of water and cement, forming a more or less dense fluid according to the amount of water that is added, the chemical reaction of hydration will begin to occur, it is exothermic, that is, it gives off a large amount of heat and hardening it is the progressive and slow acquisition of resistance over time. Various types of cements are distributed in Ecuador such as: Lafarge Holcim Ecuador, Industria Guapán, Cemento Chimborazo and Cemento Atenas, cement companies that were considered for this analysis. It was found that all the mentioned cement plants are legally adequate, meeting and exceeding the high quality standards in accordance with the INEN 2380 standard. As a result, it was obtained that Cemento Atenas has longer setting times of (251 and 303 min), in comparison to others. On the other hand, Cementos Chimborazo achieves greater resistance from the first day with 9Mpa and at 28 days, it already obtains a compressive strength of 38 Mpa, surpassing the other cements analyzed.
