The purpose of this study is to expand the use of coal ash and coal slag in thermal power plants. In addition, controlled low strength materials was developed to prevent mine settlement. Bottom ash and KR slag are mixed at ratio of 7:3 to expand the use of industrial by-products through carbonate reaction and inhibit the exudation of heavy metals. In order to efficiently fill the abandon mine, workability and physical properties were evaluated according to flow. As a result of elution of harmful substance experiment, it was confirmed that the carbonation reaction inhibited the elution of heavy metals. It was confirmed that the difference in water ratio was the difference in specific surface area of the controlled low strength materials. It was confirmed that the working efficiency is excellent when the flowability is 300mm compared to 260mm. compressive strength measurement result was relatively high at 260mm compared to 300mm because the number of pores due to decrease of water ratio was small.

In this study, to characterize the application of CSA and dihydrate gypsum Utilizing industrial byproducts, we investigated the characteristics of CSA and dihydrate gypsum to investigate the characteristics of Mine Liner according to the addition amount. As a result of compressive strength, length change and absorption rate of mining lime wastewater according to CSA addition amount, up to 30% of CSA showed a positive effect on shrinkage and absorption reduction effect as well as strength at initial age. However, due to excessive use of CSA 50%, it was reduced by 15% compared to OPC due to increase of absorption rate and decrease of cement amount due to over expansion rather than shrinkage compensation and void filling.

This study aims to find out the reason that tile adhesive(type III) for ceramic tile does not harden under some conditions especially high humidity even though long curing time. Bonding strength of adhesive between substrate and ceramic tile is evaluated depending on bonding conditions such as substrate kind(concrete, board), bonding material (tile adhesive, tile cement) and curing condition(humidity 50, 70%). Based on the results, this study aimed to establish the quality of tile adhesion strength under the relevant conditions.
