  • Effect of mineral admixture on early age cracking of concrete
    礦物摻和料對混凝土早期開裂的影響
  • Aged cracked gasoline
    陳化的裂化汽油
  • The ring test result shows that tendency of concrete cracking is consistent with shrinkage and veritifies early - age shrinkage is responsible for the concrete early - age crack
    通過圓環法混凝土抗裂試驗,驗證了混凝土收縮與開裂趨勢的一致性,進一步證明了早期收縮對混凝土早期裂縫的重要影響。
  • During the technology development of modem concrete , concrete structure crack ( especially early - age crack ) becomes more and more serious and has been one of main research directions of civil engineering
    隨著現代混凝土技術的發展,混凝土結構裂縫呈現越來越嚴重的趨勢,尤其是早期裂縫,已成為土木工程界一個重要研究方向。
  • Because of its many excellent advantages , hpc has come to be used in a wide range . but the existed projects show it ' s weakness , such as the brittleness and the tendency to early age cracking of hpc is more serious and sensitive than ordinary performance concrete ( opc )
    高性能混凝土由于其優異的性能得到了越來越廣泛的應用,但已有的工程實踐中也相繼暴露了hpc的一些弱點,如高性能混凝土的脆性和易于收縮開裂的傾向可能比普通混凝土更嚴重。
  • Early age cracking of concrete has re - emerged as an important issue all over the world in recent years . the stress , due to restrained volume change related to thermal deformation and shrinkage in the early age concrete , is the main driving force for the deleterious cracking in the construction stage . during the development of the stress , creep , a very important property of concrete , is always developing . creep contributes to 40 ? - 50 ? reduction of the elastically induced stress in the restrained specimen . ring test , a qualitative test , can provide information to assess the potential for cracking of different concrete . an overview of ring test developed in recent years and mechanism of uniaxial tensile creep test is described in this paper at first . then , an innovative test equipment based on ring test is outlined
    近年來混凝土早期裂縫問題再次引起全球工程界的廣泛關注.早期混凝土由于體積變形受到約束而產生的應力是導致混凝土開裂的主要因素.在混凝土應力發展的同時,混凝土徐變也在同時發生著變化.有研究表明,徐變能減少40 ? - 50 ?的早期應力.圓環試驗是用于定性評價混凝土材料抗裂性能的試驗方法之一.本文首先分析了圓環試驗和單軸拉伸徐變試驗的原理,創造性地將圓環試驗用于測量早期混凝土的干縮徐變,并設計了試驗方案
  • The results show that the order from large to small of the early - age crack resistance of concretes with high content mineral admixtures is high performance expensive concrete with fiber > high performance concrete with fiber > high performance concrete with hybrid fibers > high performance expensive concrete with hybrid fibers > high performance expensive concrete
    結果表明,大摻量礦物摻合料混凝土的早期抗裂性大小順序為:纖維增強高性能膨脹混凝土纖維增強高性能混凝土混雜纖維增強高性能混凝土混雜纖維增強高性能膨脹混凝土高性能膨脹混凝土。
