It was the first time that geotextile grid - bag form work was used on seashore rubble mound revetments protecting an ash storage yard. The grid - bags are made of polyester, filled with plain concrete to a thickness of 250mm. Laying of the geotextile grid - bags, concrete filling and quality control inspection are all carried out in line with pre-arranged methods and designs. The key factor in concrete pouring lies in the good flowability and workability of concrete as well as the continuity of concrete pouring. The mixing ratio of concrete used was 1 : 2- 71 : 2- 41 and W/C = 0. 67. The admixtures used were wooden calcium sulphate and AE compound.
