DISINTEGRATION OF CONCRETE IN FOUNDATION AND ANCHORAGE BLOCKS FOR AN AERIAL MAST

ALKALI-AGGREGATE REACTIONS WERE FOUND TO BE ONE OF THE CAUSES OF DETERIORATION OF THE CONCRETE IN FOUNDATION AND STAY ANCHORAGE BLOCKS FOR AN AERIAL MAST. FREEZING-THAWING AND VIBRATIONS TRANSMITTED TO THE FOUNDATION AND BLOCKS FROM THE STAYS WERE PROBABLY CONTRIBUTING FACTORS IN THE DISINTEGRATION PROCESS; THE QUESTION IS STILL OPEN AS TO WHICH OF THE THREE FACTORS WAS PRIMARY AND WHICH WAS SECONDARY. THE RISK DELETERIOUS ALKALI-AGGREGATE REACTIONS IN CONCRETE CONTAINING REACTIVE AGGREGATES IS INCREASED WHEN THE STRUCTURE OF WHICH THE CONCRETE FORMS A PART IS CARRYING RELATIVELY HEAVY DYNAMIC LOADINGS OR IS SUBJECTED TO THE ACTION OF OTHER DISINTEGRATIVE FORCES SUCH AS FROST ACTION. /AUTHOR/.
