    Abstract

    The paper deals with experimental research concerning the use of cement with the addition of slag when preparing concrete with certain desired properties. Shown are results of experimental research using cement with the addition of 20% slag, crushed aggregate, water, and admixtures, and one high-range water reducer and one “water-proofer” in order to obtain water resistant concrete of high compactness and high strength. The concrete obtained satisfied the desired conditions, using the admixtures, having a low water cement ratio (W/C) but having very good workability. The second part of paper deals with the determination of cement resistance to aggressive water. Since a cement with a sufficiently low percentage of tricalcium aluminate necessary to be resistant to seawater is not always available, we suggest the use of concrete of the highest obtainable density. The coefficient of seawater resistance is obtained by comparing the flexural strength of specimens cured for six months in ordinary water and specimens cured in simulated seawater solution for the same period of time. A higher coefficient of resistance is obtained on specimens with a low W/C, using admixtures compared to those without admixtures, both being of the same consistency in spite of the usage of cement containing a higher percentage of tricalcium aluminate.
