Description
Concrete at sea faces salt water, load stress, and slow decay through its pores, so the size and spread of those pores decide its working life. Zhaoyong Chen and co-authors test whether mixing concrete under vibration improves marine grades C30 and C50 compared with ordinary mixing. They compared water absorption, pore structure, and chloride drift in samples made both ways.
Vibration mixing cut average water absorption by about thirty percent in both grades, and the results varied far less from sample to sample. Average pore size shrank by roughly a third, and total pore volume dropped by about half. After ninety days in salt water under half load, chloride drifted through the vibrated samples about twenty percent more slowly. The authors conclude that vibration mixing tightens the pore network, densifies the concrete, and lengthens its durability at sea.
