1. Overview

The SJY-800B penetration type mortar strength tester is a new in-situ non-destructive testing method that uses a specially designed measuring nail to penetrate the mortar based on the negative correlation between the depth of the nail penetrating the mortar and the compressive strength of the mortar. The energy released by the working spring with a certain displacement is compressed, and the compressive strength of the mortar is converted by measuring the penetration depth of the measuring hole corresponding to the strength curve.

The penetration method for detecting the compressive strength of mortar in the field of on-site mortar strength testing technology is characterized by: 1. simple operation; 2. Accurate detection results; 3. The advantages of low testing cost are highly praised by users, and it is also the most widely used testing technology in on-site mortar strength testing. The industry standard of the People's Republic of China, "Technical Specification for Testing the Compressive Strength of Masonry Mortar by Penetration Method" (JGJ/T136-2001), which is used in conjunction with the promotion of this technology, was officially promulgated and implemented on January 1, 2002.

The SJY800B type penetration mortar strength tester used in the penetration method for testing mortar compressive strength technology is designed and produced by Beijing Tiandi Xinghuo Technology Development Co., Ltd. Due to the unique internal control parameters of the product, it meets the testing requirements of the curve in the industry standard "Technical Specification for Testing the Compressive Strength of Masonry Mortar by Penetration Method" (JGJ/T136-2001) of the People's Republic of China.
