THE COMPACTION OF DRY-LEAN CONCRETE (SOIL CEMENT)

IN RECENT YEARS THE TENDENCY IN AIRFIELD RUNWAY CONSTRUCTION HAS BEEN TO LAY A SUBBASE OF CEMENT-STABILIZED SOIL WITH A SURFACING OF BITUMINOUS OR DENSE CONCRETE MATERIAL. THE SOIL NORMALLY USED FOR THIS PURPOSE IS AN ALL- IN BALLAST, AND THE ENSUING MATERIAL PRODUCED IS CALLED DRY- LEAN CONCRETE. AN INVESTIGATION WAS MADE TO CLARIFY THE RELATIONSHIP BETWEEN SOME OF THE VARIABLES AFFECTING THE COMPRESSIVE STRENGTH OF DRY-LEAN CONCRETE AND TO EVOLVE A METHOD WHICH COULD BE USED FOR THE CONTROL OF MIX PROPORTIONS. THE CRUSHING STRENGTH OF PARTIALLY COMPACTED DRY-LEAN CONCRETE IS RELATED TO ITS DENSITY. THE DEGREE OF COMPACTION AFFECTED BY A GIVEN AMOUNT OF COMPACTIVE ENERGY IS RELATED TO THE MOISTURE CONTENT OF THE DRY-LEAN CONCRETE.
