COMPUTER EVALUATION OF CONCRETE QUALITY

THE HIGHWAY ENGINEER IS CURRENTLY FACED WITH AN INFORMATION AND CONSTRUCTION EXPLOSION IN WHICH IT HAS BECOME INCREASINGLY DIFFICULT TO SORT OUT THE RELEVANT FACTS IN TIME FOR THEM TO BE APPLIED, ESPECIALLY AS THE WORK PROCEEDS, TO IMPROVE THE QUALITY OF CONCRETE. PROBLEMS AND PITFALLS OF PRESENT SPECIFICATIONS AND PROCEDURES FOR CONTROL TESTING ARE DISCUSSED AND IT IS SUGGESTED THAT THESE ARE IN NEED OF REVIEW TO PLACE THEM ON A SOUNDER STATISTICAL BASIS USING ACCELERATED TESTS, ESPECIALLY FOR CONCRETE STRENGTH WHEREVER POSSIBLE. MODERN METHODS OF DATA PROCESSING, STORAGE AND RETRIEVAL ARE SHOWN TO OFFER POTENTIAL FOR THE FASTER HANDLING OF INFORMATION. AN INTEGRATED PROJECT, AT PRESENT BEING INTRODUCED BY THE DEPARTMENT OF HIGHWAYS IN ONTARIO, IS DESCRIBED. NEW REPORTING SYSTEMS HAVE BEEN ESTABLISHED TO FEED CONCRETE DATA TO A COMPUTER. THE DATA ARE THEN PROCESSED, STORED, RETRIEVED AND EVALUATED AS NEEDED FOR THE CONTROL OF QUALITY AT THE TIME OF CONSTRUCTION, THE SELECTION OF CONCRETE BEST SUITED TO A PARTICULAR STRUCTURAL DESIGN OR FOR THE STUDY OF PERFORMANCE. THE SHORT TERM BENEFIT IS IN BETTER CONTROL OF CONCRETE QUALITY AT THE TIME OF CONSTRUCTION. THE LONG TERM, AND PERHAPS EVEN MORE IMPORTANT BENEFIT, SHOULD BE THAT THE PROPERTIES OF CONCRETE WHICH INFLUENCE PERFORMANCE CAN BE IDENTIFIED AND BETTER SPECIFICATIONS PREPARED FOR FUTURE WORK. /AUTHOR/
