세라믹모르터 라이닝의 물리？화학적 특성 평가

초록

Lining materials of ceramic mortar lining technique, CMP-1800 and DR-1800, were assessed on physical and chemical properties in the study. Compared with conventional cement mortar lining materials, the physical and chemical properties of ceramic mortar lining was increased. The improvement of the physical and chemical properties on ceramic mortar lining was thought to be the effect of the binding and compaction of its configuration by SBR(Styrene-butadiene rubber) included DR-1800 and ceramic mortar powder(CMP-1800) as presented in SEM pictures. Especially, compression strength of ceramic mortar lining was 1.4 times higher than cement mortar lining. And after curing time of 16 hours, compression strength(18.5 N/mm2) of ceramic mortar lining was reached to the same compression strength(17.4 N/mm2) after 28 day curing of cement mortar lining. Therefore it was thought that drinking water service of ceramic mortar lining was possible after 16 hours curing. In addition to, Calcium loss of ceramic mortar lining was lower than conventional ductile cast iron pipe(DCIP). This results showed the resistance of ceramic mortar lining pipe was stronger than DCIP for the degradation and deterioration on aggressive water quality. And heavy metals such as Pb and Cr was not detected in all tested pipes including ceramic mortar lining pipe.
