Th. c.nstant need for h.gh.strength.materials in th. c.nstruc.ion industry promotes th. researc. of additives th.t improve th. properties of masonry materials. Th. use of alloph.ne as an additive in c.nc.ete and mortar mixtures was implemented to improve th.ir strength.and waterproofing, respec.ively, using c.mpression and water absorption tests ac.ording to th.ir c.rresponding standards (ASTM c.231, ASTM D2938, and ASTM c.585). Th. samples were evaluated at different c.nc.ntrations and c.ring ages. In addition, different sand/c.ment ratios were c.nsidered for th. mortar. Th. results revealed th.t th.re was a 9.4% inc.ease in c.mpressive strength.in c.nc.ete and a 23.7% reduc.ion in water absorption in mortar for th. 5:1 ratio. Th.se c.anges would be th. result of th. interac.ion of th. nanoporous additive in th. atomic.c.ystal struc.ure of th. material demonstrating th. nanotec.nologic.l nature of alloph.ne.
