Resumen
El presente trabajo evalúa la producción de bloques huecos de hormigón a escala de
taller local, aplicando diferentes formulaciones del Cemento de Bajo Carbono (LC3) y
cemento Portland como muestra patrón, este nuevo aglomerante se basa en la
sustitución del clínquer del cemento Portland por la combinación de arcilla calcinadapiedra caliza.
Para realizar este estudio se elaboraron en la planta piloto del Centro de Investigación y
Desarrollo de la Construcción (CIDC), LC3 con 50% y 35% de sustitución de clínquer y
una combinación 1:1 y 2:1 de arcilla calcinada-carbonato de calcio para cada uno de
ellos.
Con las muestras de LC3 se produjeron bloques huecos de hormigón, a los que se les
realizaron ensayos de absorción y resistencia a compresión con el objetivo de evaluar
sus propiedades físico-mecánicas, para determinar los requisitos visuales y de estética se
les realizó el ensayo de dimensiones y paredes exteriores, los resultados obtenidos se
compararon a la luz de lo especificado en la NC 247: 2010. Bloques huecos de hormigón.
Especificaciones, comprobando así la calidad que tienen los aglomerantes.
The present work evaluates the production of hollow blocks of concrete to scale of local Workshop, applying different formulations of the Low Carbon Cement (LC3) and Portland Cement like sample pattern, this new agglomerate is based on the substitution of the clinker of the Portland Cement for the combination of clay and calcareous roast-stone. To carry out this study they were elaborated in the pilot plant of the Center of Investigation and Development of the Construction (CIDC), LC3 with 50% and 35% of clinker substitution and a combination 1:1 and 2:1 of clay roast-carbonate of calcium for each one of them. With the samples of LC3 hollow blocks of concrete took place, to those that were carried out rehearsals of absorption and resistance to compression with the objective of evaluating their physical-mechanical properties, to determine the visual requirements and of aesthetics they were carried out the rehearsal of dimensions and external walls, the obtained results were compared by the light of that specified in the NC 247: 2010. Hollow blocks of concrete. Specifications, checking this way the quality that you/they have the agglomerates.
