Performance testing and finite element analysis of new lightweight wall materials

lightweight wall materials;  modulus of elasticity;  dry shrinkage value;  Finite elements

The elastic modulus and dry shrinkage value of the new lightweight wall material were experimentally determined, and three finite element models were established, namely the concrete unit without reinforcement, the concrete unit with reinforcement, and the concrete unit and the steel wire mesh unit working together, and according to these three finite element models, the maximum principal stress and the maximum cracking length of crack under various dry shrinkage values were calculated. The relationship between wall cracking and load, material properties, reinforcement ratio, etc., as well as the reasons for wall cracking and crushing, are analyzed, which provides a basis for the use of this new wall material in actual engineering.
