Product Specifications
Product Description
Instructions:
This mortar resiliometer makes the hammer drive the pointer to rebound and indicate rebound distance through the restoring force of instantaneous elastic deformation produced by using the spring to drive the bounce hammer and using the bounce rod to bounce the surfaces of the brick samples, and calculates the compressive strength of mortar and labels by taking rebound value as one of the relevant indexes for evaluating the compressive strength of mortar. It is used for the nondestructive testing for the compressive strength of masonry mortar in ordinary fired brick masonry for industrial and civil buildings.

Located in Laoling City, Shandong Province, with beautiful scenery and convenient traffic, Leling Concretetest Hammer Factory is a member of Concrete Quality Committee of Concrete and Pre-stressed Concrete Branch of China Civil Engineering Society and a key manufacturer of NDE structures or concrete member as well as brick work compressive strength detectors. It achieved the license for manufacturing measuring instruments in 1990.
In December 1995, it was awarded "Satisfactory Product" and "Satisfactory Unit" by China Quality Management Committee and Construction Mechanical Equipment User Committee of China Quality Management Association during the quality evaluation of national reinforcing steel bar, concrete, road construction and maintenance mechanical products.
Our concrete resiliometers were awarded "Engineering Construction Recommend Products" by Ministry of Construction. The factory produces resiliometer and resiliometer spring verification instruments in accordance with "Regulations on Concrete Resiliometer Verification (JJG817-93) of China national measurement verification regulations. Moreover, it is one of the compiling units of Technical Regulations on Rebound-method Detection of Concrete Compressive Strength (JGJ/T23-2001), the national industry standard.
