Calculation Model for Elastic Modulus of Lightweight Aggregate Concrete
摘要
Abstract
Lightweight aggregate concrete(LAC)with light weight,anti-permeability,heat preservation,heat insulation,good fire resistance and resist frozen has the better application prospect,while its elastic modulus is low and is lack of reasonable calculation model due to its different failure mechanism with normal weight concrete(NWC).The database is established with the analysis of LAC elastic modulus calculation models based on existing researches.Then a new calculation formula is advised according to analyzing the effect of strength and apparent density on elastic modulus,which is based on the accurate evaluation of models using database.It shows good agreement between the elastic modulus obtained by advised model and test results is achieved,and advised model can be used to predict LAC elastic modulus.The research on elastic modulus of LAC can provide basis for the subsequent theoretical analysis of structure and theoretical basic for the engineering application.关键词
