Concrete facilities suffer damage from acid river flow in volcanic area. Therefore, the reinforcing durability of concrete against acid solution is a important subject. And then, the reinforcing can make the construction and maintenance of concrete facilities easier.
In a purpose of obtaining the basic data for the durability of concrete against acid solution, the experiments that cement mortal prisms mixed with some mixtures soaked in sulfuric acid solution and hydrochloric acid solution have been carried out, In the experiments, a fly ash, a blast-furnace slag and a high performance AE water reducing agent were used for the mixtures.
These effects of the mixtures against the both acid solution were recognized. But, they showed different effects for the each acid solution, and for researched items. The change in quality of prisms in sulfuric acid solution were remarkably. The effects of fly ash was recognized to be significant and the ratio of 30% in weight was appropriate for mixing.
