Various challenges encountered in the construction industry has led to the production of concrete, with not just high strength, but also with enhanced durability properties. Several research works have been carried out using replacement of constituent materials and introduction of various admixtures in concrete. Alccofine is one of such promising micro fine material. This study investigates the performance of hardened concrete using nano materials. Effects of alccofine (AL) and zinc oxide (ZnO) on the durability and strength of hardened concrete were explored. Series of tests were conducted by substituting cement by weight with 10% AL and adding ZnO in proportions, 0.25%, 0.5%, 0.75% and 1%. Based on the results obtained, the strength properties of concrete reduced as cement replacement level rose beyond 10%. The durability performance of the concrete, in terms of rapid chloride permeability, water permeability test, sea water attack and chloride resistance, was within acceptable limist, even as the ZnO was increased. This study has generally proposed a sustainable solution to produce durable concrete that could have useful aaplication in the construction industry.

This paper presents the test examination done on porousness qualities of solid utilizing “Alccofine”. The evaluation picked for the examination was M-20 evaluation of cement concrete. The variety was concentrated on the examples exposed to solidify supplanted by different rates of alccofine (0, 10, 12, 14 and 16 rates separately). Casted examples are relieved in climatic temperature and solidified properties of cement are tried at 7 and 28 days and RCPT was led at 28 and 35 days and the outcomes acquired are looked at. The test outcomes show that the specimen permits 2000 to 4000 Coulombs giving medium rating according to ASTM 1202. The RCPT esteems show improved opposition for chloride penetrability and low pace of consumption chance level.
