Within the scope of this diploma thesis we studied the influence of white Portland cement and its content on properties of injection grouts with binder composed of hydrated lime and white Portland cement. Powdered stone was used as filing material. Water content in the grouts was reduced with chemical admixture (PPh superplasticizer). The tests were performed on the fresh and hardened grouts. On fresh grouts mixture we have performed the test of fluidity and bleeding test and we also determined the water retentivity and the flow value. On hardened grout we have performed the measurement of shrinkage and we have determined flexural strength and compressive strength. The phenolphthalein test was also used to determine the level of carbonization. All the tests and measurements were carried out in the laboratory of the Faculty of Civil and Geodetic Engineering of University of Ljubljana.
