Fracturing of Rock with Expansive Cement
Publication: Journal of the Geotechnical Engineering Division
Volume 108, Issue 10
Abstract
A study was conducted to determine the efficiency of a highly expansive cement (called Bristar) used to fracture rock and concrete. The 48-hour expansive pressure of the cement, calculated to be about 46 MPa (6700 psi), is independent of hole size when tested in steel, thick-walled cylinders. Because the pressure is constant, a scaling relationship of S/d emanates from elastic theory, where S is the spacing between boreholes and d is the borehole diameter. However, the rate of pressure development is a function of cement temperature; consequently thermodynamic considerations may be as important as hole spacing. At the same scaled distances, 38-mm (1.5-in.) boreholes fracture dolomite 24-48 hours sooner than 12.7-mm (0.5-in.) holes. Optimal spacings in dolomite ranged between 8 and 16 borehole diameters.
