  1. Test results show that the steel fiber in concrete have more effectiveness on improving the splitting tensile strength and the flexural strength in the early age than after its hardening ; the flexural modulus of elasticity of sfrc are higher than the plain concrete at different ages while their compressive modulus of elasticity are almost the same. it ' s also shown that, similar to the plain concrete, the early - age loading decreases the strengths of sfrc, but, with the increase of the contents of the steel fiber things are getting better, especially for the splitting tensile strength and the flexural strength

    試驗結果表明:與性能穩定之後相比,在混凝土中摻入鋼纖維對它的早期劈裂抗拉強度和抗折強度有尤為顯著的提高作用;對各齡期的受壓彈性模量影響不大,而對提高抗折彈性模量有一定的效果;與素混凝土試件相同,在早期(強度達到28天強度的85前)對鋼纖維混凝土試件施加荷載會對它的各種強度產生一定的不利影響,但是摻入鋼纖維可以減輕這種不利影響,尤其對劈裂抗拉強度和抗折強度作用突出,並且含纖率越高,效果越明顯。
  2. Standard test method for measuring early - age compressive strength and projecting later - age strength

    測量早期抗壓強度推測出後期抗壓強度的標準試驗方法
  3. 2. the research results indicate that the physical mechanical properties of hbc concrete such as compressive strength, flexural strength, splitting tensile strength, elasticity modulus and etc. is equivalent to that of opc concrete at age of 28d and remarkably surpasses opc concrete at 90d though its early age strength ( 3d, 7d ) is relatively lower. moreover, the relation of w / c ratio of hbc with compressive strength as well as strength at 7d with 28d ( c50 - c80 ) has been established and the effect of the dosage and type of fly ash on compressive strength of hbc has also been studied

    研究了高貝利特水泥高性能混凝土的抗壓、抗折、劈拉、彈性模量等一系列物理力學性能,結果表明,和opc混凝土相比, hbc混凝土早期( 3d 、 7d )抗壓強度、抗折強度、劈拉強度、彈性模量較低,但隨著齡期的增加, hbc混凝土28d諸項強度基本與之持平, 90d則全面超過opc混凝土;探討了高貝利特水泥高性能混凝土水膠比與28d抗壓強度的關系以及c50 c80強度范圍內高貝利特水泥高性能混凝土7d強度與28d強度的關系;此外,對粉煤灰摻量及品種對高貝利特水泥高性能混凝土抗壓強度的影響也進行了研究。
