Assessment of Parameters Affecting Compressive Behavior of Mineral Wool Iinsulations

For load-bearing mineral wool insulations, compressive stress at 10% deformation is animportant property which is studied as a function of density. The determination ofcompressive behavior of insulations is not a simple and fast test procedure. However, it can be estimated with indirect test method of determination of density which is simple and fast. For indirect test of 􀄱10, it is necessary to find the relations of 􀄱10 and 􀈡 for estimation of mechanical behavior of mineral wool insulations without testing or testing them once in a while. Here, the wool structure, organic content, aging effects on compressive stress for glass wool, rock wool and slag wool are investigated.
