Modifying Stucco Mortars with Additions of Sulphoaluminate Cement and Aluminate Cement

Abstract:

Stucco products due to the specific nature should be characterized by a short time of the beginning and end of setting, low shrinkage, good adhesion to the substrates and workability at running. The type of cement used has a significant influence on this parameter. The change in the physical properties of stucco mortars in which Portland cement was gradually replaced with AliCem sulphoaluminate cement and Górkal 70 aluminate cement. For this purpose, two sets of samples were prepared, in the first set the percentage of Górkal 70 cement in relation to the entire cement was 15, 20, 25, 30 and 33%, in the second set the percentage of Alicem cement was 25, 50, 75 and 100%. The research results indicate that both cements significantly shortened the setting time of the mortars, reduced the shrinkage and improved adhesion to the substrates.
