DETERMINING THE CEMENT CONTENT OF CONCRETE AND MORTAR

THE POSSIBILITIES OF DETERMINING THE CEMENT CONTENT OF CONCRETE AND MORTAR ARE INVESTIGATED. GOOD RESULTS ARE OBTAINED IF THE CEMENT AND SAND FROM WHICH THE CONCRETE OR THE MORTAR WAS MADE CAN BE ANALYZED TOGETHER WITH THE SAMPLE OF CONCRETE OR MORTAR. THE CALCULATIONS ARE CARRIED OUT ON THE BASIS OF THE QUANTITIES OF SILICON DIOXIDE AND CALCIUM OXIDE WHICH ARE RESPECTIVELY SOLUBLE IN HYDROCHLORIC ACID AND IN SODA SOLUTION. FOR SLAG CEMENTS THE DATA AS TO THE CONTENT OF SOLUBLE MANGANESE OXIDE ARE EMPLOYED. IN THIS CASE THE RELATIVE ERROR IS NOT MORE THAN PLUS OR MINUS 5 PERCENT. THE COARSE AGGREGATE IS SEPARATED AND DOES NOT AFFECT THE RESULT. IF THE SAND OR THE CEMENT IS NOT AVAILABLE, AVERAGE VALUES FOR THE CONTENT OF SOLUBLE SILICON DIOXIDE OR CALCIUM OXIDE, BASED ON VARIOUS ANALYSES OF A PARTICULAR CEMENT OR A SAND DEPOSIT, ARE EMPLOYED. THE CALCULATIONS ARE, IN THAT CASE, AFFECTED BY SOME DEGREE OF ERROR, ESPECIALLY IF THE CEMENT IS NOT KNOWN. THIS IS MORE PARTICULARLY TRUE OF COUNTRIES WHERE THE CEMENT IS ALLOWED TO CONTAIN VARIOUS ACTIVE MINERAL ADMIXTURES. /AUTHOR/
