THE PURPOSE OF THIS REPORT IS TO DEFINE THE EXTENT OF THE PROBLEMS THAT EXIST WITH RESPECT TO THE DETERIORATION OF CONCRETE FROM REACTIONS INVOLVING /A/ HYDRATION OF PARTIALLY OR COMPLETELY DEHYDRATED COMPONENTS OF THE AGGREGATE, AND /B/ REACTIONS OF ORGANIC MATERIALS ASSOCIATED WITH AGGREGATES. THE FIRST PART OF THIS ASSIGNMENT IS TO THEORIZE AS TO WHAT COMPOUNDS COULD EXIST IN EITHER NATURAL OR ARTIFICIAL AGGREGATES IN FORMS IN WHICH THEY MIGHT CAUSE DISTRESS IN CONCRETE BY COMBINING WITH WATER. THIS APPROACH APPLIES ALSO TO WHAT MIGHT BE CLASSED BY-PRODUCT AGGREGATES SUCH AS CINDERS AND SLAGS. /AUTHOR/
