Abstract Lignosulfonates are waste products of the pulp and paper industry. The effects of various metal-cation-containing lignosulfonate-based plasticizers on the properties of concrete mixtures produced using cements with various Ca(SO4)·2H2O, tricalcium aluminate, and tetracalcium aluminoferrite contents were investigated. A-type cement, which had lower tricalcium aluminate and alkaline contents, greater fineness, and higher SO3 content than B-type cement, exhibited better water reduction. Setting times of A-type cement and its lignosulfonate mixtures were shorter than those of B-type cement by 9–11%. The highest 28-day compressive strength of 41 MPa was found for A-type cement with a calcium-lignosulfonate salt admixture.
