Recently, Interest about SHCC(Strain-Hardening Cementitious Composite) that improve tensile and bending properties than existent concrete that do of this construction new material is rising. But field application is very difficult owning to difficult of manufacturing of SHCC with large fiber volume fraction by concrete manufacture process, and mechanical properties is influenced
by workability and fiber dispersibility. This study is thus comparing mechanical properties of SHCC like compress, bending and tensile strength between by concrete batching plant and by 30ℓ2-shaft mixer in laboratory.
It is proven that compress, bending and tensile stress of PVA-SHCC manufactured by concrete batching plant was lower 20% and above than by 30ℓ2-shaft mixeris. One side, in this study, mechanical properties of low sand-binder ratio PVA-SHCC is higher than high sand-binder ratio.
