Abstract:The penetration resistance method was introduced into the compressive strength testing of traditional mortar for cultural heritage building. Taking traditional mortar as the research object, such as pure lime, lime mortar with various proportions and  mortar, the correlation between the traditional mortar  joints and the penetration depth of mortar test blocks in manual green brick masonry was studied, and a linear regression formula was obtained. The traditional mortar compressive strength growth test with age was carried out, the curves of compressive strength growth of various mortars with age were established. According to the formulation method of testing strength curve required in Technical specification for testing compressive strength of masonry mortar by penetration resistance method (JGJ/T 136—2017), the testing strength curve of traditional mortar penetration resistance method was established. The verification of actual engineering projects shows that the accuracy of the curve is good, and it can be used to measure the strength of the traditional mortar of the type studied in the wall masonry of cultural heritage buildings.

Keywords:cultural heritage building;traditional mortar;testing of penetration resistance method;testing strength curve;compressive strength
