LEACHING OF CEMENT FROM A CONCRETE PILE SECTION BY GROUNDWATER FLOW

THE FACTORS GOVERNING LEACHING ARE DISCUSSED. A LABORATORY EXPERIMENT IS DESCRIBED TO DETERMINE THE INFLUENCE OF HORIZONTAL GROUNDWATER FLOW AT VARIOUS VELOCITIES ON THE LEACHING OF CEMENT FROM A CONCRETE PILE SECTION. RESULTS INDICATE THAT THE MOST SEVERE SEEPAGE GROUNDWATER FLOWS OCCURRING IN PILING WORKS WOULD NOT CAUSE SIGNIFICANT LOSS OF CEMENT FROM WELL-GRADED, CORRECTLY PLACED CONCRETE IN A FLUID STATE. SURFACE LEACHING TO A LIMITED DEPTH WILL OCCUR AT SEEPAGE VELOCITIES GREATER THAN 5 CM/SEC. /RRL/
