standard cementitious grouts have two frustrating limitations
(PRWEB) June 01, 2013
Standard cementitious grouts have two frustrating limitations: One, the inability to effectively penetrate rock microfractures or dense, silty sand soils, and two, poor performance due to the deleterious curing problems inherent in standard concrete.
PROBLEM 1: Microfractures allow water in or through, and, in the case of underground waste confinement facilities, radionuclides and other toxins out. If the rock fractures are too small, effective penetration and seal is not possible using a standard cementitious grout. As for necessary performance, standard cementitious grouts are simply unacceptable for many applications in terms of hydraulic permeation resistance, compressive strength, and effective lifespan.
PROBLEM 2: Massive structures need to be fixed into stable soil. If weak soils needs to be stabilized, permeation grouting can often be the answer…unless the soil is too dense for Ordinary Portland Cement (OPC) grouts to permeate to the proper depth and saturation point.
SOLUTION: Inject an ultrafine, pozzolanically-charged cementitious grout.
RESULT: Mines, storage caverns, and transportation tunnels remain dry behind a protective grout curtain. Tunnels are efficiently driven without fighting costly water infiltration. Earthen dam cores and critical embankments are solidified. Concrete dams and the surrounding bedrock aprons are sealed tight. Weak soils are strengthened to carry heavy structural loads and mitigate liquefaction. Transuranic wastes are sealed away for tens of thousands of years.
