摘要: Considering the advantages of energy conservation and reducing construction skill requirement workers, a new type interlocking hollow block using recycled aggregates concrete (IHB-RAC) with compressive strength up to 10 Mpa was proposed, which could help improve more than 56% efficiency compared commonly used blocks. In order study mechanical properties promote application this in building engineering, masonries considering different strengths mortar grouting holes were designed, corresponding shear strength, as well failure mode studied according test results. Then, experimental results calculated values obtained from Chinese code GB50003-2011 check suitability standards. make an accurate prediction masonry, modifying coefficients suggested positive contributions connecting keys. addition, results, appropriate calculation method for accurately predicting grouted IHB-RAC masonry proposed by separately effort hole concrete.
