Sentence examples for changes of cement from inspiring English sources
The diffusivity changes of cement pastes are predicted from a series of 3D diffusive lattice networks which are converted from the microstructures of cement pastes with micro-cracks.
Effects of GO nanosheets on microstructure and mechanical properties of cement composites were investigated by observing shape changes of cement hydration crystals and testing mechanical strength.
