实际工程中的混凝土服役结构并不仅处于单一因素作用下,至少存在两种及以上的环境因素对其产生影响,多种因素对混凝土的劣化作用不是简单的叠加,而是存在相互耦合关系.掺入纤维可使得混凝土的阻裂增韧强度性能提高,限制了混凝土的裂缝,提高了混凝土性能.研究纤维混凝土在实际多场耦合环境作用下的性能变化规律,可充分识别纤维混凝土的应用潜质,为进一步工程应用提供依据.通过国内外研究成果总结了目前对于纤维混凝土在多场耦合作用下的时变和空间损伤最新研究状况,指出了研究存在的缺口与不足,提出了可进一步研究的方向,为系统全面地认识纤维混凝土的力学、耐久性能仍需进行的研究提供思路.
Review on the degradation of fiber reinforced concrete properties under multiple field coupling
The concrete service structure in the actual engineering is not only under the action of a single factor,there are at least two and more environmental factors on its impact,a variety of factors on the deterioration of concrete is not a simple superposition,but there is a mutual coupling relationship.Adding fiber can improve the cracking resistance and toughening strength of concrete,limit the crack of concrete and improve the performance of concrete.The research on the behavior change of fiber reinforced concrete under the action of actual multi-field coupling environment can fully identify the application potential of fiber reinforced concrete and provide basis for further engineering application.Through research results at home and abroad at present are summarized for space and time-varying damage of fiber reinforced concrete under the effect of multi field coupling to the latest research situation,points out the research gaps and deficiencies,and put forward the direction of further study,which provides ideas for the research that still needs to be carried out to systematically and comprehensively understand the mechanics and durability of fiber reinforced concrete.
