Testing Methods for the Next Generation of Concrete

项目名称：	Testing Methods for the Next Generation of Concrete
摘要：	The objectives of this project are to perform a thorough literature review to determine if there are existing test methods that can quantify the performance of concrete with respect to cracking, durability and heat generation at the mix design phase. Preference will be given to test methods based on the following criteria: (1) Testing will be conducted on conventional portland cement concrete containing coarse aggregate – not mixture components, derivatives, or specialty mixes (e.g., paste, mortar, grout, ultrahigh performance concrete (UHPC), reinforced cement concrete (RCC)); (2) The time for completion does not exceed 30 days for testing; (3) The testing techniques do not utilize any hazardous materials; (4) Tests are relatively uncomplicated – a person with a high-school education can perform; and (5) Cost of testing equipment should support a wide deployment – total cost not to exceed $30,000.00. The project will review the available literature related to testing of concrete to assess potential for excessive shrinkage, potential to experience excessive temperature rise, and chloride and sulfate durability. The research team will categorize any successfully identified test methods into categories as follows: (1) Category I – Test meets current needs of FDOT without any modifications; (2) Category II – Test can be modified to successfully meet Florida Department of Transportation (FDOT) needs; (3) Category III – Test shows some potential to meet FDOT needs, but does not meet one of the main criteria listed above. Any successfully identified testing methods will be used to make recommendations to the Standards Specification for Road and Bridge Construction to be used in the concrete mixture approval process specified in section 346.
