| Research Abstract |
Recently,effective use for industrial waste has been advanced. However,the use of fisheries waste is far behind. The author has been conducting a study on the recycle of surf clam.In the past researches,the mortar with burnt shells of surf clam expanded. As a result of the experiment,normal mortar did not change the length,but "alternative mortar mixed with burnt surf clam shell powder" turned to great expansion .
The factor that caused it to expand is calcium oxide(CaO) included in clam powder. The mortar expanded due to calcium hydroxide(Ca(OH)2) derived by the reaction of CaO and H2O.HP10(10% replaced with clam powder) did not change after it expanded at first because it is thought that the reaction of clam powder and water finished after one day passed.
