N2 - The present research is focused on the design of mixtures containing zeolite (Z), as an alternative aggregate and their use in the production of blocks with lightweight and insulating properties that comply with the specific requirements of standards for its application in construction. To improve lightweight and insulating properties in blocks, first mixtures zeolitic sand/cement/lime (ZS/C/L) were prepared and their compression resistances were evaluated. After that, mixtures with the best compression resistances were choice to evaluate lightweight and insulating properties. Mixtures with the best properties (compression resistance, lightweight, and thermal conductivity) were use to make blocks by pressing in an industrial machine. Properties like compression resistance at 28 days after being cured, weight and thermal conductivity were evaluated in blocks and compared with those made out from traditional mixtures containing river sand (RS), C, and L. Results reveals that it is possible design alternative blocks with the following characteristics and properties: weight of 11kg (15.4% lower than traditional block), thermal conductivity of 0.37W/m°C (77.30% less than traditional bocks [1.63W/m°C]), and compression resistance at 28 days of 74kg/cm2 (above the resistance required [60kg/cm2] in blocks).
