Influence of the sand on the mechanical properties of mortars made with different brands of cement. Cienc. ergo-sum [online]. 2022, vol.29, n.1, e153.  Epub 22-Ago-2022. ISSN 2395-8782.  https://doi.org/10.30878/ces.v29n1a9.

The mechanical behavior of cement pastes was evaluated using Portland Cement Type II 30R from five brands, to identify the optimal relationship of the cements with different types of sand to make mortars. Five series of pastes and mortars were made with each brand of cement, varying the type of sand per series in the mortars. The resistance of cement pastes is different for each brand. The same brand of cement will have a different behavior depending on the sand used. Sand influences compressive strength. To improve the mechanical performance of the mortar, the component materials are analyzed. A specific mix design optimizes the mortar in construction.

Palavras-chave : granulometry; mechanical tests; compression; maximum resistance.
