Abstract (en)

Results of the study of creeping of mineral wool (MW) slabs under compressive stresses σс within the relative interval of 0,25σс/σ10%0,6 are presented. According to the experimental data the field of linear creeping at σс/σ10%0,35 is established. The dependence of compliance Ic of mineral wool slabs at creeping on the value of compliance ε0/σс under compressing stress σс=0,35σ10% is revealed. The change in compliance at creeping Ic during the time is accounted by the coefficient mi. The possibility of prognostic assessment of creeping deformation of mineral wool slabs under the permanent compression stress of σс=0,35σ10% for advance of 10 years according to empiric dependences for Ic and mi is presented.
