Abstract: Service life provisions in structural design have long been ignored in our country.Insufficiencies for durability requirements in current design codes for concrete structures are illustrated.To make the design adequate for concrete structures against environmental effects,many factors should be considered including the design service life,the environmental agents that cause concrete and rebars deterioration,selection of materials and mix-proportion for durable concrete,structural details to mitigate and delay the material degradation,quality control in construction as well as predetermined measures for structure maintenance and inspection in service.Service life prediction based on degradation model is also needed for those important infra-structures such as highway bridges and harbors subjected to chlorides attack.

Abstract: Flowability,passing ability and anti-segregating are required from a Self Compacting Concrete(SCC) in the fresh state,so it is not only a highly flowable nature but also a good consistency that SCC should have.In this case,a common principle was introduced for the mix design and the theory of continuous-grading of compact packed aggregates was expounded.The relationship of slurry of cementitious materials,sand factor and carpolite was investigated in order to develop fine SCC.

Abstract: Through concise introduction of characteristics and development of assembled concrete buildings both home and abroad,relations between general structure system and special structure system of assembled concrete and design requirements are systematically summarized.Technical direction and thoughts about domestic development of assembled concrete buildings is further proposed.

Abstract: Revision of the Standard for Evaluation of Concrete Compressive Strength(GB/T 50107-2010) is expounded and it is discussed that which method should be adopted for evaluation of concrete compression strength during implementation of the standard provides guiding significance for engineering technicians to understand and implement the new standard.
