Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of test equipment, especially relates to a rubber particle and composite geopolymer coating layer tensile-shear strength integrated intelligent tester. BACKGROUND

[0002] With the increasing of waste tires, rubber products have been widely used in every corner of life, and these rubber products can cause serious pollution to the environment and waste resources if not handled properly after use. Rubber concrete is a civil engineering composite material made of concrete as base material and mixed with rubber powder. The rubber powder mainly improves the internal structure of the concrete through physical action, without changing the chemical properties of various materials in the concrete. In the rubber concrete, the rubber powder plays a role similar to elastic fiber as a small material group, which can reduce various stresses and constraint microcracks of the system, thereby reducing crack generation and preventing or slowing down the development of microcracks that cause concrete rupture; at the same time, it forms a structural deformation center that absorbs strain energy, absorbs a large amount of vibration energy, and can significantly improve the impact resistance and shock absorption performance of the concrete. Compared with ordinary concrete, rubber concrete has good durability, shock absorption performance, impact resistance, anti-burst performance, heat insulation performance and sound insulation performance, and can better meet the needs of the building market. In recent years, rubber concrete has made pioneering progress in engineering applications.

[0003] However, the direct use of rubber particles can cause the cube compressive strength, splitting tensile strength, axial compressive strength and flexural strength of rubber concrete to decrease to different degrees with the increase of rubber content. Existing research shows that modification of rubber particles can improve the mechanical properties of rubber concrete.

[0004] Among them, most of the physical modification is to modify the rubber particles with a composite inorganic material coating, and the interfacial adhesion after modification can be used as the main criterion to characterize the modification. For the tensile and shear tests of rubber materials in this field, the implementation methods in domestic and foreign journals are too rough, and the existing test equipment is simple, has poor continuity, single function, and cannot obtain data in time, and cannot well represent the bonding capacity of rubber particles and composite inorganic material coating.

[0106] In one embodiment of the utility model, since in the prior art, a test process is usually carried out on one sample, leading to the need to repeatedly perform preparation steps in multiple test processes, whether repeatedly removing the residual base material or adhesive on the surface of test table 4, will lead to reduced test efficiency. Therefore, in the technical solution, an annular guide rail 5 is arranged circumferentially on test table 4, and a sliding block 7 is limited to slide along guide rail 5, driving electric push rod 9.1, hydraulic rotating machine 8.3, clamp 6 and other structures to rotate relative to test table 4 to adjust the position, so as to satisfy that one test can be performed on several samples, through sequentially fixing multiple double-layer base materials on test table 4 along a straight line, using sliding block 7 to move the position along annular guide rail 5, repeatedly testing the multiple double-layer base materials, and after the test is completed, cleaning the residual multiple base materials on test table 4, which not only fully improves the test efficiency, but also can compare the data of multiple repeated tests, take the average value, and improve the measurement accuracy of tensile and shear tests.
