| Abstract: | An early cracking is often found in the structure constructed with pumped concrete. JEA-10 Expansion Agent satisfies the pumpability of concrete and meanwhile effectively prevents and lessens an early cracking in the pumped-concrete structure. The article mainly introduces the development and application of JEA-10 Expansion Agent. |

| Keywords: | pumped concrete early crack free expansion and confined expansion |
