摘要

本文介绍了纤维增强水泥基(FRCM)体系单侧加固、双面加固和不加固砌体受压墙体的抗拉强度测试结果。试验模型由蒸压加气混凝土SOLBET OPTIMAL 4/600砌体单元制备。墙体采用预拌砂浆，M5级薄层缝，无填头缝。PBO纤维网格嵌入在矿物基质中作为表面强化。砌体墙的侧面用预拌砂浆PBO- mx GOLD砌体加固，嵌有网格PBO- MESH GOLD 22/22。然后，采用预拌砂浆PBO-MX GOLD砌体面层。所使用的表面强化为破裂模型提供了额外的强化和它们在破坏后的更安全行为。

The effect of the strengthening of AAC masonry walls using FRCM system

This paper describes results from testing the tensile strength of compressed masonry walls strengthened with fiber-reinforced cement matrix [FRCM] system on one side, both sides, or without any strengthening. Test models were prepared from masonry units made of autoclaved aerated concrete SOLBET OPTIMAL 4/600. Walls were built with a ready-mixed mortar for thin layer joints of class M5, without fi lling head joints. PBO fi bre grids embedded in a mineral matrix were used as superfi cial strengthening. Lateral surfaces of masonry walls were strengthened with ready-mixed mortar PBO-MX GOLD MASONRY with embedded grid PBO--MESH GOLD 22/22. Then, the surface layer of ready-mix mortar PBO-MX GOLD MASONRY was applied. The used superfi cial strengthening provided an additional strengthening of the cracked models and their safer behaviour after failure.
