| 摘 要： | 为研究碱激发矿渣陶粒混凝土空心砌块(alkali-activated slag ceramsite concrete hollow block,简称AASCHB)砌体的弯曲受拉性能,完成了108个用Mb25～Mb90碱激发矿渣陶砂砂浆(alkali-activated slag mortar with pottery sand,简称AASM)砌筑的AASCHB砌体的弯曲受拉性能试验.试验结果表明:GB 50003—2011表B.0.1-2中所给公式不能准确预估AASM砌筑的AASCHB砌体的弯曲抗拉强度,砂浆强度低于70.3 MPa时,沿通缝截面弯曲抗拉强度预估值偏高,砂浆强度介于70.3～91.9 MPa时,沿通缝截面弯曲抗拉强度预估值偏低;当砂浆强度低于46.2 MPa时,沿齿缝截面弯曲抗拉强度预估值偏高,砂浆强度介于46.2～91.9 MPa时,沿齿缝截面弯曲抗拉强度预估值偏低.同时发现AASCHB砌体弯曲抗拉强度不但与AASM的抗压强度有关,而且受水灰比、砂灰比、Na_2O含量和水玻璃模数的影响.基于试验结果,分别建立了AASCHB砌体沿通缝截面和沿齿缝截面弯曲抗拉强度的计算公式.
