화산력-시멘트 혼합 바이오 블록의 미생물 생장 특성

초록

This research aims to utilize lapilli from the Mt. Baekdusan as environmently-friendly construction material. First of all, the neutralizing method forfabricating lapilli-cement-mixed bioblock was examined. And then, by use of the neuralized bioblock with microorganism for water purification, thegrowth inhibition effect against the pathogenic coliform bacillus was evaluated. The result regarding growth inhibition effect on pathogenic coliform bacillus indicates that the pretreatment condition, which is a concurrent processionwith aqueous solution of 10% di-ammonium Phosphate after water curing, led to pH degraded below 10 which was the target value. Therefore it wasconcluded that the method was effective on bio-block neutralization. The microorganisms purifying water and di-ammonium phosphate were detectedthrough the examination for microorganism existence on the bioblock, therefore it was concluded that the bioblock composed of lapilli and cement is ableto be utilized in various structures as an environment friendly construction material.
