Creep	Creep of Concrete
Averaging Factor, K1	Correction factor for aggregate type in predicting average value. See Concrete Properties in the Technical Guide for additional information.
Bounding Factor, K2	Correction factor for aggregate type in predicting upper and lower bounds. Concrete Properties in the Technical Guide for additional information.
Shrinkage	Shrinkage of Concrete
Averaging Factor, K1	Correction factor for aggregate type in predicting average value. See Concrete Properties in the Technical Guide for additional information.
Bounding Factor, K2	Correction factor for aggregate type in predicting upper and lower bounds. See Concrete Properties in the Technical Guide for additional information.
Agg. Splitting Strength, fct	If the aggregate splitting strength of a lightweight concrete is known, check the box and input the value.
