Determinación de la influencia de la ceniza de cascarilla de arroz en el tiempo de fraguado, en la elaboración de bloques huecos de hormigón que cumplan con las especificaciones de la norma INEN 3066

Abstract

The present study reveals how rice husk ash influences the setting time, and the physical-mechanical properties that occurs in the partial substitution of percentage by weight of cement for it, through test specimens with different percentages 5%, 10%, 15% and 20%, for the manufacture of hollow concrete blocks, which must meet the characteristics that qualify them according to the INEN 3066 standard. The dosage of materials provided by the artisans was used, it began with the analysis of the light aggregates: chasqui and white powder through laboratory tests to characterize their properties, followed by the manufacture of hollow concrete blocks with 5%, 10%, 15% and 20% replacement percentages by weight of the cement by rice husk ash. A qualitative and quantitative analysis is carried out, the quantitative ones are represented by the results of the tests of resistance to simple compression and the absorption percentage that each one of the blocks presents, according to the NTE INEN 3066 standard, the qualitative analysis is it taken at the moment of accepting the sample and determining its visual aspects, these depend on the form of manufacture so that they are within compliance with the current standard.
