STADIUM’s advanced concrete analysis is the most up to date method of analyzing the material properties of concrete by taking into account the results of controlled laboratory testing as well as all mix design specifications. To accurately predict a particular concrete’s ability to resist ionic penetration in the natural environment is very important when determining management, maintenance schedule and service life of a steel reinforced concrete structure.
STADIUM analysis can be performed on cores cut from existing structures, as well as on both field and lab cured samples in order to optimize mix design for a particular project.
CTE has a dry cure room solely dedicated to STADIUM testing procedures. This is not required, but was created in order to ensure the most accurate and precise results.
Drying Test- STADIUM modeling software will calculate a moisture transport coefficient (MTC) by using results of a drying test (Modified version of ASTM C1585).
Modified Rapid Chloride Penetration Test (ASTM C1202) takes a precisely cut portion from a concrete cylinder core, or cylindrical sample. Utilizing a precision manufactured \ testing cell filled with NaCl and NaOH a closely monitored electrical current forces ion exchange through the sample. These readings are then interpreted to produce and Ion Diffusion Coefficient (IDC). The assistance of the ion rich solution and electrical current reduces this process exponentially and creates more accurate results.
Porosity (ASTM C642) uses a concrete sample soaked in lime water until cured for 28-days. This test is to determine particular density, absorption and void space of concrete samples.
