Article Preview

In the paper there is presented the influence of different types of co-polymer dispersion additives onto the magnitude of shrinkage and strength properties of cement composites. The effect of application of such additives was compared and confronted with the action of widely used classical admixture reducing shrinkage based on multi-molecular alcohol (propylene alcohol). As a result of conducted tests the significant reduction in shrinkage strains and increase in bending strength was observed due to the application of co-polymer dispersion with the amount of at least 5% of the cement mass. Reduction of shrinkage and improvement of serviceability properties to great extent prejudge the technical attractiveness of co-polymer and cement materials for the cases of concrete structures repairs and constructing industrial floors without joints.
