    摘 要:通過碳化實驗,測定了加氣混凝土砌塊在碳化條件下的收縮變形、碳化深度,碳化后加氣混凝土砌塊的抗壓強度和抗折強度。研究結果表明:實驗室碳化條件下加氣混凝土砌塊的收縮發展呈現三個階段:(I)早期快速發展階段,(II)穩定階段,(III)加速發展階段;表面砂漿層能夠明顯降低碳化收縮的發展,加氣混凝土砌塊碳化深度與碳化時間成正比,抗壓強度和抗折強度都隨著碳化的發展而下降。 Abstract: Through the carbonation experiment, the shrinkage deformation, carbonation deep, compressive strength and flexural strength of autoclaved aerated concrete blocks are measured. The results indicate that the shrinkage development of aerated concrete blocks under lab carbonation condition is divided three stages: (I) early age rapid developing stage,(II) steady stage and (III) accelerating developing stage. The surface mortar of autoclaved aerated concrete blocks can obviously decrease the carbonation shrinkage value. The carbonation deep of autoclaved aerated concrete blocks is proportional to the carbonation time, and the compressive strength and flexural strength decrease with the carbonation development.

    摘 要:通過纖維增韌水泥基復合材料(ECC)單軸拉伸試驗,研究了ECC的拉伸應力-應變關系曲線,分析了砂膠比、纖維類型、粉煤灰及礦渣含量等因素對ECC拉伸應變能力的影響規律。試驗結果表明,ECC的拉伸應變能力對于組分及配比較為敏感,增加粉煤灰含量可有效提高ECC的拉伸應變能力;增大砂膠比及礦渣含量可以提高材料初裂強度及極限抗拉強度,但不能提高ECC的拉伸應變能力;鋼纖維的摻入對于提高材料的應變硬化能力及實現多裂縫開展能力不利。 Abstract: Uniaxial tensile text has been carried out to study the tensile stress-strain relationship of engineering cementitious composites(ECC), and the influence laws of sand-binder ratio, fiber types, fly ash content and slag content on ECC’s tensile strain ability have been analyzed. Experimental results show that the tensile strain ability is sensitive to the ingredients and mixing proportions. The tensile strain ability would be improved effectively with the fly ash content increasing in general. The increase of sand-binder ratio and slag content is helpful to improve the first-crack strength and ultimate tensile strength of ECC, but it can’t improve the tensile strain ability of ECC. Moreover, adding steel fiber is disadvantageous to improve the strain-hardening ability and the development of multi-fractures of ECC
