Apneno-cementne injekcijske mešanice z belim cementom : diplomska naloga

Premk, Erik (avtor), Bokan-Bosiljkov, Violeta (mentor)

V okviru diplomske naloge smo analizirali vpliv belega Portland cementa in njegovega deleža na lastnosti injekcijskih mešanic s kombiniranim apneno-cementnim vezivom. Kot polnilo je bila dodana kamena moka. Delež vode smo zmanjšali s pomočjo kemijskega dodatka (superlastifikator PPh). Preiskave smo opravili na svežih in strjenih mešanicah. Na svežih mešanicah smo preverjali pretočnost, izločanje vode, vodozadržnost in razlez. Na strjenih mešanicah smo merili krčenje in določili upogibno natezno trdnost in tlačno trdnost. Za preverjanje stopnje karbonatizacije smo uporabili fenolftaleinski indikator. Preiskave in meritve so bile izvedene v Konstrukcijsko prometnem laboratoriju Fakultete za gradbeništvo in geodezijo Univerze v Ljubljani.

Izvleček

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.
