Estudio comparativo de la adición de partículas de puzolanas naturales en compuestos de cemento Portland para el desarrollo de elementos arquitectónicos

Abstract

Abstract:Research currently focuses on the basic science of cementitious material at the nano/atomic level. Researchers improve the durability and sustainability of concrete and have achieved a significant increase in mechanical properties by incorporating pozzolans (nano-sílica). The following research intends to analyze the effect of the addition of natural pozzolans existing in the Paltas canton of the province of Loja, on the mechanical characteristics, durability and microstructure of the cement mortar paste, as well as its application in the preparation of a prototype of constructive material: tile. And its respective comparative analysis with two types of cement: ordinary Portland cement and pozzolanic cement. It is expected that the addition of natural pozzolans will reduce the setting time, increase the resistance to compression and water absorption, and that the digestion of calcium hydroxide crystals will lead to a decrease in the size of the crystals accumulated in the interface.
