Abstract: A cement paste composition includes a curable component including a cementitious material and a zeolitic imidazolate framework-67 (ZIF-67) present in an amount of 0.01 to 3% by weight based on a total weight of the cementitious material. The composition further includes water in an amount of 30 to 50% by weight based on a total weight of the cement paste composition. A cured specimen made from the cement paste composition has a compressive strength of 30 to 80 megapascal (MPa) according to ASTM C109/C109M-21 standard test method, and a direct tensile strength of 1.2 to 2.2 MPa according to ASTM C307-18 standard test method. The ZIF-67 particles are uniformly distributed throughout the cured specimen. A method of producing the cement paste specimen.
