| Abstract: | To achieve high crack and permeability resistance,fly ash,polypropylene fiber and high efficiency wa-ter reducer were mixed into the concrete prepared for canal lining machine. When the mixing ratios are 20%～25%, 0.9kg/m^3 and 1%for fly ash,polypropylene fiber and high efficiency water reducer respectively,the compressive strength and impermeability of concrete can be up to 26.2 MPa and W8 grade,which satisfy the construction re-quirements of concrete for canal lining machine. |
