超高韧性水泥基复合材料(UHTCC) 是一种新型高性能纤维增强水泥基复合材料, 自20 世纪90
年代出现以来, 引起了世界范围内的关注. 该文综述了该材料在土木工程结构应用相关方面的 …

Flexural behaviors of reinforced ultra-high-performance fiber-reinforced concrete (UHPFRC)
beams were experimentally and numerically investigated in terms of reinforcement ratio. To …

The restrained ring test is becoming widely used as a standard test method to assess the
potential for early-age cracking in concrete mixtures. Previous research focused on the …

The cracking problem in concrete is widespread and complex. This paper reviews the
problem and focuses on those parts of the problem that are more readily solved. Polymer …

The size-effect of structural element has been experimentally determined in concrete
members under various load types. The importance of size-effect on safe structural design …

Experimental and numerical analyses were performed to characterize the early age tensile
creep and shrinkage behavior of concrete. A uniaxial restrained shrinkage test was …

In this thesis different mechanical properties for shotcrete (sprayed concrete) such as
compression strength, bond strength, bending tensile strength, elastic modulus, free and …

Concrete experiences volumetric changes as a result of material formation (cement
hydration), thermal variations, or moisture losses. If these volume changes are prevented by …

O objetivo principal deste trabalho foi adaptar metodologias para avaliação da fissuração
em revestimentos de argamassas e para medidas de retração livre e restringida à partir da …

Fiber reinforcement, which can restrain the propagation of micro-cracking, is effective in
improving the early-age cracking resistance of concrete. Polypropylene fibers have been …
