This study was a result of mock-up test for the field application which was compared between low heat cement and temperature-reducing binder with the way of temperature crack reduction. The result of mock-up test was shown that the heat of hydration from the low heat cement and the temperature-reducing binder indicated 44 and $54^{\circ}C$ respectively.

This paper presents the result of a mock-up test and field application of concrete that is black in color thanks to the application of superplasticizer containing carbon amino silica black (CASB-SP). Mock-up specimen with a size of $3000{\times}1500{\times}40$ mm was fabricated with black concrete applying 0.5% of CSAB-SP with 27 MPa. After dividing the zone in wall mock-up specimen, three different water repelling agents were applied to verify its effect of efflorescence prevention. It was found that the use of CASB-SP with 0.5% made the black concrete develop a highly clear black color, and the epoxy type water repelling agent had better performance in efflorescence prevention. Based on mock-up test, field application was conducted with bridge member. It was also found that the application of CASB-SP showed favorable results in black color development.

Construction project is completed through several stages and problems of each stage affect directly not only now but also next. Defect of 2D drawings influence in construction phase, and it make many loss on project. Nowadays we practically use real Mock-up test in construction sites to solve the problems. But it also has many problems which are waste much money and time. Therefore, this study tries to analyze effect that is occurred by appling BIM Mock-up simulation instead of real Mock-up execution. These analysis is conducted by comparing two construction building site. These have same shape but one is made for BIM Mock-up, and another is real Mock-up. Comparison points of view are cost, time and operator's satisfaction. It is expect that BIM Mock-up is more effective at low cost and on shorter time. But our analysis show that each are conducted different part of function. So new Mock-up type is required. Hybrid Mock-up is combine real mock-up with BIM simulation and it can minimize risk of project.

In the cold-weathering concrete construction, it is important to ensure stable strength development of concrete in a low temperature environment. In this study, Non-curing cement(NCC) using the classified high fineness cement and self-heating powder was investigated for stable strength development without curing in a low temperature environment (less than $0^{\circ}C$). The actual size Mock-Up tests by various cement type and curing condition are performed to evaluate the strength development and hydration heat of concrete.

This study was performed to development 80MPa high strength concrete using local raw material of Busan and to estimate field application ability. As the result of three types of mixture, fresh and hardened properties were satisfied with target requirement properties. Hydration temperature was revealed mean 75$\sim$85$\circ$C. Additionally, in case of compressive strength, core specimen's strength is six times higher than field curing specimen by very high hydration heat.

This study is to evaluate the feasibility of the mix design for exposed concrete. Mock-up sized specimens were prepared, and a flowing concrete method was selected for placement. Results showed that the fluidity and air content of fresh concrete achieved target values, the compressive strength at 7 days was 27 MPa, and surface roughness was in the range of between around 1.53 and 1.68 ㎛, which was in the quality level. Therefore it is concluded that the proposed mix design for exposed concrete can be applied in practice.

The ultimate objective of this research is to develop the technologies for the construction of 100-year housing as the first task for improving housing environments. The technological development of 100-year housing makes it possible to advance construction technologies and part development, to develop long-life housing with durability and Flexibility responding to customers' needs for future living space. At first, for this purpose, the applications according to the types of the Standard Model of Long-life Housing are proposed to respond to the life-cycle of near-future demographic and social structure, and the construction of the Mock-up House execute based on the location selected during the 2nd year and the basic plan. Then the Standard Model of Long-life Housing are advanced and proposed through evaluating the field applicability of the Mock-Up House.
