SOIL STABILIZATION : INVESTIGATION OF A CHEMICALLY MODIFIED CEMENT AS A STABILIZING MATERIAL

LABORATORY AND FIELD TESTS WERE MADE TO DETERMINE THE EFFECTIVENESS OF CHEMICALLY MODIFIED CEMENT AS A STABILIZING MATERIAL FOR A LEAN CLAY SOIL AND ESTABLISH VALIDITY OF STRENGTH REQUIREMENTS PROPOSED FOR A STABILIZED SOIL SURFACE TO BE USED FOR SHORT-TERM MILITARY OPERATIONS. INITIAL LABORATORY TESTS REVEALED THAT 5% PORTLAND CEMENT + 1% SODIUM SULFATE WAS AS EFFECTIVE AFTER 24 HRS. CURING AS 10% PORTLAND CEMENT (UNMODIFIED). SUPPLEMENTARY LABORATORY TESTS CONDUCTED CONCURRENTLY WITH FIELD TESTS INDICATED SULFATE MODIFICATION TO BE ESSENTIALLY INEFFECTIVE FOR THE TEST SECTION BECAUSE THE SOIL DIFFERED IN CHEMICAL CHARACTERISTICS FROM THE SOIL USED IN THE INITIAL TESTS. A SOIL SURFACE STABILIZED WITH 5%-CEMENT-1% SODIUM SULFATE, CONSTRUCTED ON A 4CBR SUBGRADE, DEVELOPED SUFFICIENT STRENGTH IN ONE DAY TO MEET SPECIFIED TRAFFIC REQUIREMENTS, DUE TO STABILIZING ACTION OF THE CEMENT.
