The aimof the research was to determine the influence of the use of Portland cement with the addition of various types of aluminum cement on the basic physical and mechanical properties of grouts and mortars. CEM I 42.5R and three types of aluminumcement containing 40, 50 and 70%Al2O3 were used for the tests.Mixtures were made containing 4, 6, 8, 10 and 12% of different grades of alumina cement. The time of the beginning and the end of the bonding was determined for them. Based on the obtained research results, the optimal proportion of Portland cement to alumina cement was established. For this proportion, the compressive strength tests were carried out after 1, 2, 7 and 28 days of maturation of the mortars made with them, and the strength of their adhesion to the concrete substrate was determined. The analysis of the obtained test results showed that by using the addition of 6% high-alumina cement, a similar immediate setting effect can be obtained and a clearly better adhesive strength as when using 12% low-alumina cement.
