SUMMARY:

Civil construction is one of the most polluting and waste generators. In order to minimize the impacts is crucial to increase the resistance and durability of cement composites to promote the sustainability of this sector. Researchers suggest the use of carbon nanotubes (CNTs) as reinforcement of the cementitious matrix. Those nanomaterials act as a nucleator of the hydration products and increase the strength. The present work seeks the effects of carbon nanotubes dispersed on the anhydrous particles of cement in a non-aqueous solution of isopropanol. Thus, cement paste with 0.05% and 0.10% of CNTs properties are tested according to mechanical and microstructural properties. It is expected to understand the influence of CNTs dispersed in isopropanol solution in the cement hydration process on a microstructural scale, relating to the mechanical behavior.
