Durability testing includes: concrete bubble spacing, shrinkage and expansion measurement, nitrogen infiltration, concrete freeze-thaw, sulfate dry-wet cycle, concrete carbonation, alkali-aggregate reaction, dynamic modulus, impermeability, electric flux, chloride ion diffusion, concrete creep and so on.
Specific tests are aimed at special tests, including adiabatic temperature rise, setting time, concrete rheology, 5G temperature measurement in special environment, ammonia measurement by fly ash, powder-liquid reaction, water consumption/water binder ratio determination, alkali content, ion leaching, air permeability and so on. , are concrete solutions.
As the name implies, mechanical tests include: pressure test, bending compression test, universal material test, repeated bending test of steel bar, manhole cover pressure test and so on.
These are the project directions that concrete testing will use, and large-scale projects cover more aspects of scientific research projects.
