Laboratory Testing of Electro-Osmotic Pulse Technology to Reduce and Maintain Low Moisture Content in Concrete

摘要

Electro-Osmotic Pulse Technology stops water intrusion through concrete. Water can enter a structure via seepage or through joints and cracks. Electrodes are installed in the concrete and the adjacent soil. A small voltage (up to 30 VDC) is applied between the electrodes producing an electric field across the concrete. The electric field promotes cation, anion, and water molecule movement within the concrete; creates counterflow and associated pressure that opposes seepage; pulse technology allows some moisture to be retained within the concrete preventing overdrying.
