摘要

为考察碱激发矿渣陶粒混凝土空心砌块（alkali-activated slag ceramsite concrete hollow block

简称AASCHB）砌体的轴心受压性能

完成了由强度等级为MU7.5、MU10、MU15的AASCHB和强度等级为Mb20、Mb25、Mb30的碱激发矿渣陶砂砂浆（alkali-activated slag mortar with pottery sand

简称AASM）砌筑的36个砌块砌体试件的轴心受压试验.试验结果表明:AASCHB砌体的抗压强度随AASCHB抗压强度的增大而增大；而AASM抗压强度对砌体抗压强度的影响相对复杂.用AASCHB和AASM砌筑的砌块砌体轴心抗压强度试验值普遍低于按GB 50003—2011《砌体结构设计规范》砌体轴心抗压强度计算公式的预估值.在《砌体结构设计规范》砌体轴心抗压强度计算公式的基础上

通过引入AASM特性系数

调整砂浆强度影响修正系数

建立了以AASCHB抗压强度和AASM抗压强度为关键参数的这类新型砌块砌体的轴心抗压强度计算公式.

Abstract

To investigate the axial compressive performance of alkali-activated slag ceramsite concrete hollow block (AASCHB) masonry

a total of 36 masonry specimens of the AASCHB at MU7.5

MU10

and MU15 as well as alkali-activated slag mortar with pottery sand (AASM) at Mb20

Mb25

and Mb30 were tested. Results show that the axial compressive strength of the AASCHB masonry increased with that of AASCHB

while the axial compressive strength of the AASM had a complicated impact on that of the masonry.Based on the formula provided in Code for Design of Masonry Structures(GB 50003—2011)

the estimated values of the axial compressive strength of the masonry using AASCHB and AASM are generally higher than the experimental results.By introducing the characteristic coefficient of AASM and adjusting the correction coefficient of the axial compressive strength for mortar

a formula for the axial compressive strength of the new type of block masonry with the key parameters of the compressive strength of AASCHB and AASM was proposed

which is in accordance with the codified formula of the masonry axial compressive strength adopted in Code for Design of Masonry Structures.
