This research is a comparative analysis of the surface gloss of concrete depending on the coating material added to the cast, and includes analyses of the surface gloss of specimens made of cement mortar, with and without the addition of superplasticizer. In terms of coating material, the 7th material, which is part of a liquid packaging material, was shown to have the highest gloss, and was followed by the 3rd material, which uses transparent film. As the level of gloss is shown to vary depending on the material used for the coating film, it can be interpreted that the surface gloss can differ depending on surface particles and chemical composition factors. To make a concrete surface smooth, it is more effective to use a coating material with impermeability and a highly dense surface.

Recent local advantages to improve the aesthetics of building materials connected with one of the trend of Exposed Concrete and Construction Method in various facilities and to diversify Showing a tendency to both application and development. This exposed concrete form of the features and materials is, the impact of large commercial viability and can consider I can apply to the surface of construction on a surface The diversification of the material was soon exposed directly linked to the varying aesthetics of concrete, and currently take advantage of the form of material is based on such important factor in our country Based on the concept of Exposed Concrete utilized by some construction site, design and be considered is very important elements of the put to practical use.

In this study, the concept of exposed concrete is basically considered and various expressions of concrete surface texture are verified variously. Based on this comparison, the characteristics of exposed surface of concrete according to the change of coating material applicable to formwork are compared and analyzed. I am trying to find a way to apply exposed concrete in a convenient way, In order to observe the characteristics of concrete exposed surface according to the form material, As the surface is smooth and tight, the surface condition of the concrete is smooth and the pore is small.

This paper presents an experimental study on the air contents and the chloride penetration in offshore concrete depending on the types of forms. Three types of concretes(plain, MSF, and FA concretes) with four kinds of forms(wood, coating wood, steel, and polypropylene film) were investigated. The test results show that the air contents in the concrete cured with steel and polypropylene forms were higher than those with wood and coating wood forms. The concrete with wood forms has the least air content. The variation of chloride ingress time was large depending on the types of forms on the same concrete, i.e. 13.2, 20.3, and 17.7% for Plain, MSF, and FA concretes, respectively. Consequently, the surface conditions of forms should be considered for design of durable concrete.
