WEATHER EFFECTS ON CONCRETE

THE NATIONAL SCIENCE FOUNDATION HAS MADE A GRANT TO NOTRE DAME PROFESSOR KENNETH LAUER FOR HIS CONTINUING STUDY OF THE RELATIONSHIP BETWEEN THE BREAKUP OF CONCRETE SLABS, THE COMPOSITION OF PARTICULAR CONCRETES, AND SPECIAL WEATHER PATTERNS. TWO EXPERIMENTAL SLABS ARE BEING USED, IN WHICH ARE EMBEDDED INSTRUMENTS TO MEASURE CHANGES IN TEMPERATURE, MOISTURE CONTENT AND LENGTH (FROM STRAIN). ONE OF THE ASPECTS OF THE STUDY IS THE EFFECT OF WEATHER DURING THE EARLY MONTHS OF A PAVEMENT'S LIFE, WHEN THE CONCRETE GAINS STRENGTH AS THE CEMENT ABSORBS WATER. ANOTHER GOAL IS TO DEFINE THE EFFECTIVE FREEZE--THAW CYCLE AND DETERMINE THE AVERAGE NUMBER OF CYCLES EACH WINTER. THE FINAL GOAL IS TO DEVELOP A COMPUTER PROGRAM TO PREDICT CONCRETE DURABILITY FROM ITS COMPOSITION AND LOCAL CLIMATIC CONDITIONS.
