Demand for stone products used as building materials is increasing. The construction industry, the value of the stone industry is sufficient, but the domestic stone industry is very lag regarding IT utilization. However, the overseas stone industry produces high-quality products using IT. In this study, we want to offer an IT application technology priority fit for the stone industries. We identify the current status and production process of the stone industries, then set the priority of various IT, so that obtain competitiveness in the domestic stone industries, and minimize the gap between the overseas stone industries. Therefore, we used AHP method; stone industry production processes were selected as the Enterprise Operation Management, Quarrying, Manufacturing, Construction and Maintenance of first-tier. The second-tier ones are consisted of 30 factors out of IT elements. Focus group interviews were conducted to confirm the validity of each factor. As a result, most important factors of first-tier was selected as the order of Manufacturing, Quarrying, Enterprise Operation Management, and Construction & Maintenance. The top 5 of 30 factors in the second-tier were selected Smart Sensor, Mobile Device, Robot of manufacturing, GIS of quarrying, and SCM of enterprise operation management. And the factor that relatively less important was GPS of construction and maintenance. If properly applied an IT application technology for stone industry, we expect to provide efficient production lines and increase customer satisfaction, which will ultimately expand the promotion for the industry and thus act as positive factor in promoting the stone industry.

Stone Industry in our country is classified mainly in view of supply of raw materials ingredients, as follows: Stone-Quarrying Industry who develops the natural resources, Stone Processing Industry who processes the quarried raw ore into construction materials and stone-products, Stony Mountain-Aggregate Industry who supplies the elementary raw materials ingredients to construction section, respectively. Among them, while Stone Processing Industry sells its turnover around billion-Won level per annum per a company, most of other job sites are paltry, adopting less than 10 employees, and it is real state that their working environments are also very coarse. The Noise originated from processing-instrument which generates at such Stone Processing Industry is as so repeatedly reiterating Loud Noise that most of the spot workers are forcedly imposing such dangers as the severe unpleasant feeling and hearing impairments. On this viewpoint, this Research is now analyzing on the frequency characteristics with regard to the Noise that generated from various processing-instruments, and then based on this, in order to grasp the influence of the Loud Noise generating when process the stone materials, this study has ever evaluated it with PSIL and NR. It is considered that such data could be used as the valuable material for establishment of a comfortable working environment hereafter.

Stone powder sludge is a byproduct of the crushed aggregate industry, and most of it is dumped with soil in landfills. The disposal of stone powder sludge presents a major environmental problem. This paper investigates the effects of stone powder sludge on the fluidity, density, strength and micro-structure properties of AAC(autoclaved aerated concrete) samples. Stone powder sludge was obtained from a crushed aggregate factory in order to investigate its applicability as a substitute for quartz sand in AAC. To determine the properties of the AAC samples produced with stone powder sludge, specimens containing different foam ratios were produced. Flow value, density, compressive strength, tensile strength and flexural strength of the samples were tested, and X-ray diffraction (XRD) was performed. The test results indicated that the compressive strength of AAC specimens (F120) with stone powder sludge was higher than that of AAC specimens (Q120) with quartz sand for same foam ratio of 120%. For all XRD diagrams, a higher number of tobermorite peaks was shown for the F120 sample than for the Q120 sample, which may explain the slightly higher strength gain in the F120 sample.
