《砖石工程施工及验收规范》(GBJ203-83)第3.0.13条规定:“水泥砂浆中掺入有机塑化剂时,砌体抗压强度应较水泥混合砂浆砌体降低10％。”关于砌体强度如何换算为砂浆强度,《建筑技术》1986年第4期“施工中有关砌筑砂浆的两个问题”一文介绍了换算方法,即先将砌体强度乘上1.1,然后按提高后的砌体强度,由《砖石结构设计规范》(GBJ3-73)表1查出对应的砂浆强度值。此文刊出后,有的读者提出,换算时不应将砌体强度乘上1.1,而是应该除以0.9。
Article 3.0.13 of the “Code for Construction and Acceptance of Masonry and Stone Projects” (GBJ203-83) stipulates: “When cement mortar is mixed with organic plasticizers, the masonry compressive strength should be reduced by 10% compared with cement-mixed mortar masonry.” Regarding how the masonry strength is converted into the strength of mortar, the translation method is introduced in the article “Construction Techniques, Two Issues Concerning Masonry Mortar in Construction” in 1986, which first multiplies masonry strength by 1.1 and then presses After the masonry strength, the “masonry structure design specification” (GBJ3-73) table 1 to find out the corresponding mortar strength value. After this article was published, some readers suggested that the masonry strength should not be multiplied by 1.1 in the conversion, but should instead be divided by 0.9.
