Zaczyny cementowe o niskiej gęstości i podwyższonej wytrzymałości na ściskanie

The requirements for lightweight cement slurries besides to density are the thickening time, rheological parameters and compressive strength of the cement. The minimum compressive strength of the cement allowing for start work in the hole after the cementing casing is 3.5 MPa, while 14 MPa allows for correct interpretation by geophysics. The article presents the results of tests on light cement slurries in the density range from 1.46 g/cm3 to 1.61 g/cm3, whose minimum compressive strength 3.5 MPa was achieved after 12 hours from the end of the cementing process and exceeds value of 14 MPa after 48 hours WOC.
