This paper reports the research and application of high fly ash content concrete (HFCC) with Dipy construction formwork. Concrete construction using Dipy construction formwork can skip the processes of form stripping and concrete vibration. According to the research of the working principle of concrete with Dipy construction formwork, it can be found that cement paste composed of high fly ash c...

Portland cement concrete has clearly emerged as the material of choice for the construction of a large number and variety of structures in the world today. This is attributed mainly to low cost of materials and construction for concrete structures as well as low cost of maintenance. Therefore, it is not surprising that many advancements in concrete technology have occurred as a result of two dr...

this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...

21 Abstract 22 23 This paper reports on the North American state-of-the-art in the use of FRP composites in concrete structures. For new 24 construction, FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for 25 a host of reasons. The principles for design and construction have been established and proposed to industry by the American ...

The paper reports the results of a joint project on evolutionary design of reinforced concrete structures in tall buildings. It has been conducted at the Center for Concrete Structures at the Darmstadt University of Technology in Germany and in the School of Information Technology and Engineering at George Mason University. Its ultimate objective is to revolutionize design of both steel and con...

The paper reflects current state of popularization of static elasticity modulus of concrete. This parameter is undoubtedly very important for designing of concrete structures, and very often neglected and rarely determined before designing concrete technology itself. The paper describes assessment and comparison of four mix designs with almost constant dosage of individual components. The only ...
