Influence of cement grinding fineness on mortar properties

Used in the construction of buildings, bridges, castles, factories, hydroelectric plants and other structures, cement has been an essential element in the development of the modern world. It is used in these structures in various forms such as concrete and mortar. This study aims to evaluate the effect of cement fineness on mortar properties. The initial setting time of different sizes such as 90µm, 63µm 40µm, called A, B and C were 151, 133 and 115 respectively. During the production of mortars with these different sizes, it was shown that within two days of age, the compressive strength for A, B and C samples were 16.65, 19.45 and 23.1 MPa respectively. These values reached 50.25, 55.05 and 57.9 MPa after 28 days for the same samples. On the other hand, after two days, the flexural strength reached 3.25, 3.86 and 4.49 MPa for A, B and C respectively, while it was 6.98, 7.02 and 7.22 MPa.
