Life Cycle Model of Ultra High Toughness Cementitious Composites Exterior Walls

Abstract:

In order to research ultra high toughness cementitious composites (UHTCC) economic rationality, this paper chooses the ultra high toughness cementitious composites thermal insulation wall as the research object, uses the study of life cycle method. Establish full life-cycle model with basic life-cycle economic evaluation principle. Evaluate its economic rationality. The results show that ultra high toughness cementitious composites facade has a longer life cycle than ordinary concrete wall. And their local repair costs are all the same, but their maintain frequencies are different. UHTCC facades facing layer does not require maintenance. The calculated models of the two walls are different.
