新型薄层砂浆砌筑砌体抗压强度预测

Prediction for Compressive Strength of New Type of Thin Mortar Masonry

为了能够较准确地预测薄层砂浆砌筑砌体的抗压强度值,通过对30个试件进行了砌块砌体的抗压试验;基于规范建立了薄层砂浆砌筑混凝土砌体抗压强度的数学模型,研究了砌体受压破坏过程和破坏机理,对比了薄层砂浆与普通砂浆砌筑砌体的抗压性能。结果表明,本文模型具有可行性,且薄层砂浆能提高砌体的抗压强度。

In order to predict the compressive strength of thin mortar masonry accurately, compression test of block masonry for 30 specimens was conducted. Based on the specification, a mathematical model of compressive strength of concrete masonry mortar layer was established, the failure lprocess and failure mechanism of masonry compression were studied. The compressive properties of thin mortar and ordinary mortar masonry were compared. The results show that the model is feasible and the compressive strength of masonry mortar can be improved.
