【背景资料】某5层砖混结构宿舍楼,7度抗震设防。墙厚240mm,墙长48m,宽12m,实际地质情况为西部地基土为中偏高压缩性土,而东部较坚硬。因紧邻该建筑的东侧建有同类型的房屋,并具有详细的地质勘察资料,故建设方省去了地质勘察,要求设计院按该地质勘察资料确定地基承载力。在房屋报建时因无地质资料,未获审批,后不得不补做了勘察,但此时基础已施工完成。施工方为了赶工期,新招进一劳务作业队伍进行墙体砌筑,发现砌筑砂浆层饱满度为75%,皮数砖同缝,多处转角和纵横墙丁字相交处的施工临时洞口处留直槎等情况,当房屋建至5层,墙面开始出现少量细微裂纹,随后逐步发展为裂缝,且不断增多。 请根据上述背景资料完成以下选项。 蒸压加气混凝土砌块施工时的含水率宜小于20%。
