| 摘要: |
| 为研究碱激发矿渣陶粒混凝土空心砌块砌体的受剪性能,对108个用Mb25~Mb130碱激发矿渣净浆和用Mb25~Mb80碱激发矿渣陶砂砂浆砌筑的碱激发矿渣陶粒混凝土空心砌块砌体进行抗剪试验.试验结果表明:碱激发矿渣净浆作砌筑浆体的砌体抗剪强度低于碱激发矿渣陶砂砂浆作砌筑浆体的砌体.碱激发矿渣陶砂砂浆作砌筑浆体的砌体抗剪强度低于用水泥砂浆和混合砂浆作砌筑浆体的砌体.砌体的抗剪强度随砌筑浆体抗压强度的提高而增大,Na2O含量、砂灰比对砌体抗剪强度的影响不容忽视.基于试验结果,分别建立了用碱激发矿渣净浆和碱激发矿渣陶砂砂浆作砌筑浆体时的碱激发矿渣陶粒混凝土空心砌块砌体抗剪强度计算公式. |

| Abstract: |
| To investigate the shear performance of alkali-activated slag ceramsite concrete hollow block masonry,tests on 108 masonry prisms with Mb25~Mb130 of alkali-activated slag paste and Mb25~Mb80 of alkali-activated slag mortar with pottery sand were carried out. The results show that the shear strength of masonry with alkali-activated slag paste was less than that with alkali-activated slag mortar, and the shear strength of masonry with alkali-activated slag mortar was lower than that with ordinary cement and composite mortars, respectively. The shear strength of masonry increased as the compressive strength of alkali-activated slag paste and mortar increased. The effects of Na2O contents and sand to cementitious materials ratios on the shear strength of masonry should not be ignored. Based on the results, the formulae for the shear strength of alkali-activated slag ceramsite concrete hollow block masonry with alkali-activated slag pastes and mortars were developed, respectively. |
