Study on Durability of Externally Lightweight Aggregate Concrete at Negative Temperature Mixed with Perlite
This paper discusses the durability of light aggregate concrete with perlite in negative temperature environment,and analyzes the influence of negative temperature environment on the performance of light aggregate concrete with perlite,it includes the change of strength,impermeability,Frost resistance and the applicability of perlite lightweight aggregate concrete in this environment.This paper introduces the material composition,characteristics and basic theory application of perlite lightweight aggregate concrete.Based on the comprehensive analysis of the performance of concrete in negative temperature environment,a series of durability experiments were designed under the simulated negative temperature environment,and the experimental data were analyzed,the durability of perlite lightweight aggregate concrete was evaluated.The corresponding research results provide scientific basis for the selection and application of concrete construction materials under negative temperature environment,and have certain significance for improving the service life and safety of such materials,it not only provides theoretical basis and technical support for concrete construction in cold area,but also provides new ideas and methods for the durability research of concrete materials.
