Method for determination of pressure of hydro-break of cement stone includes placement of cement stone in testing chamber, supply with hydraulic pump of liquid to testing chamber, gradual increase of liquid pressure, visual observation of liquid outflow from testing chamber and observation of pressure change, at that before gradual increase of pressure of liquid from testing chamber one lets air out, observation of pressure change and control of operation of hydraulic pump one carries out by means of device for information processing, by data obtained and processed by the device one plots an approximated curve of change of pressure in time, and pressure of hydro-break is determined by point of the curve plotting coming to plateau, with averaging not less that two carried out in sequence experiments. |
