EN 13412:2006 (E) 4 1 Scope This European Standard specifies two
17、methods for determining the modulus of elasticity in compression for repair products and systems. Method 1 is for products and systems with high creep characteristics typically those containing polymer binders (PC). Method 2 is for products and systems with low creep characteristics typically those
18、containing polymer modified (PCC) and cementitious (CC) binders. 2 Normative references The following referenced documents are indispensable for the application of this document.
