Concrete slump testing is an important part of providing quality concrete. Comparing test results in this new program should improve quality of concrete testing.
According to the authors of a recent article on concrete testing in ACI’s Concrete International magazine, improving the quality of concrete testing can be achieved by stressing education and quality.
“Improving the Quality of Concrete Testing” discusses an innovative program named “Test Fest” that encourages technicians to self-assess competency and improve proficiency. The Colorado Ready Mixed Concrete Association (CRMCA) testing program provides an opportunity for technicians and laboratories to compare their concrete test results versus the average of many technicians and laboratories. The authors believe that the program is a valuable introspection and educational exercise, and if implemented by testing agencies, should improve the quality of concrete testing.
Their recommendations to further improve concrete testing include:
Technicians obtain sample during the CRMCA Test Fest session. Note that the technician in the yellow vest and white hardhat has white plastic sheeting to protect the first portion of his composite sample from rapid evaporation. This a requirement of ASTM C172/C172M that is not commonly adhered to in the field.
