RAPID ANALYSIS OF FRESH CONCRETE - PART 1

A CHEMICAL METHOD IS PRESENTED FOR DETERMINING THE CEMENT AND WATER CONTENT OF CONCRETE ON SITE, WITHIN FIFTEEN MINUTES OF SAMPLING. THE BASIS OF THE CEMENT DETERMINATION IS THAT CEMENT CAN BE DISBURSED IN WATER AND HELD UNIFORMLY IN SUSPENSION SO THAT A REPRESENTATIVE SAMPLE MAY BE TAKEN BY PIPETTE. A STANDRAD ONE-TUB WASHING MACHINE IS USED. IT IS FILLED WITH A KNOWN VOLUME OF WATER, AGITATED AND WEIGHED CONCRETE PLACED IN THE WATER AND MIXED. FLAME PHOTOMETRY IS USED FOR THE DETERMINATION OF THE CALCIUM CONTENT OF THE SUSPENSION. PROCEDURES ARE DESCRIBED IN DETAIL IN THE APPENDIX. IT IS CONCLUDED THAT THE RAPID METHOD ANALYSIS DESCRIBED PROVIDES A GOOD MEANS OF QUALITY CONTROL.
