Difference between Internal and External Hydration of Hardened Cement Paste under Microwave Curing

In order to investigate the difference between internal and external hydration of hardened cement paste under microwave curing, a comparative study on the hydration products, hydration degree, fracture morphology, and pore structure between the inner part and outer part of hardened cement paste (Φ12...
