Which mechanical effect results when Roman concrete sets in seawater?

💡 Explanation

The interlocking crystals of tobermorite form because of the reaction between volcanic ash, lime, and seawater, causing CRYSTAL INTERLOCKING. This creates expansive strength, therefore the cement matrix is reinforced, rather than eroded as with modern materials in seawater.
