A new method is proposed to estimate pumping pressure based on concrete composition without experimental measurements. Previous studies show that the pumping pressure depends on the interface friction between concrete and the wall of the pumping pipes. This friction is determined by the thickness and the rheology of the boundary layer formed at the interface.

Higher cement content mixes are generally easier to pump. The difference between a typical 3000 PSI mix and a typical 4000 PSI mix is that there is approximately 100 pounds more of cementious material and approximately 85 pounds less sand in the 4000 pound mix. Cement is the sliding agent in concrete; while sand is abrasive

Over time water and ice can damage the concrete inside the crack and work around the grout. This method is especially unreliable with hairline cracks and where water pressure and water flow is present. Low pressure injection also works better with rigid grout that exerts more of its own force as it cures and expands into the crack.

Low pressure injection crack repair begins with the surface sealing of the crack and the placement of the surface ports along the crack opening. The best material for this is epoxy pastes. Epoxies bond very effectively on to clean, dry roughened concrete surfaces. This is accomplished by scraping the crack area with a wire brush.
