OBSERVATIONS ON THE RELATIVELY HIGH STRENGTH OF CHALK- AGGREGATE CONCRETE

IT HAS BEEN OBSERVED THAT CONCRETE CONTAINING CHALK AGGREGATE HAD A HIGHER COMPRESSIVE STRENGTH THAN OTHERWISE SIMILAR CONCRETE WHICH CONTAINED BASALT AGGREGATE, ALTHOUGH THE CHALK ROCK HAD A LOWER COMPRESSIVE STRENGTH THAN THE BASALT. MEASUREMENTS OF THE RATES OF DEVELOPMENT OF HARDNESS OF CONCRETE CONTAINING THESE AGGREGATES, MEASUREMENTS OF THE SURFACE AREAS OF THESE AGGREGATES AND X-RAY EXAMINATIONS OF THE CRYSTAL PHASES IN THE SET CEMENT ARE REPORTED AND DISCUSSED. IT WAS CONCLUDED THAT THE RELATIVELY LOW STRENGTH OF CONCRETE CONTAINING BASALT AGGREGATE MAY BE DUE TO DEVELOPMENT OF A PHASE, NOT CHEMICALLY IDENTIFIED IN THE PRESENT WORK, WHICH HAD A RELATIVELY WEAK BONDING STRENGTH TO THE AUGITE CRYSTALS IN THE BASALT CONCRETE. /AUTHOR/
