Changes in Shrinkage after the Application of Insulation to the Concrete Surface

Article Preview

Abstract:

Concrete shrinkage is affected by the application of hydro insulation or in contrary by the removal of hydro insulation membrane from the concrete elements. Changes in shrinkage are influenced by the age of concrete, the size of the concrete element and the ratio between the different drying surface areas. This paper deals with the evaluation of the long term measurements performed in elements sized 300 x 300 x 300 mm and the application of the acquired knowledge into the modern B4 model.
