Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete performance testing technology, specifically relating to a molding die for concrete performance testing. Background Technology
[0002] Concrete is one of the most important materials in civil engineering construction. As an artificial stone, it is made by uniformly mixing cementitious materials, aggregates, water, and necessary admixtures and additives in a certain proportion and then compacting it into a dense form. Concrete has the characteristics of high compressive strength, good durability, and a wide range of strength grades. However, many concrete products are often of inferior quality, and their strength is unsatisfactory. This is especially true for some key national construction projects, which have very high requirements for concrete strength standards. Therefore, testing the strength of concrete is necessary and essential.
[0003] In existing technologies, when testing concrete properties such as compressive strength, flexural strength, splitting tensile strength, and modulus of elasticity, it is usually necessary to first fabricate rectangular concrete blocks that are easy to test. However, when making concrete blocks, a single mold can only accommodate the production of one fixed-size concrete block. For different performance tests, multiple different types of molds are required, resulting in poor applicability and high costs. Utility Model Content

[0009] An adjustment component may be disposed between the fixed limiting structure and the movable clamping unit for forming a variable molding cavity with the substrate, the first open cavity and the second open cavity.

[0017] In one possible implementation, the fixed limiting structure includes:
[0018] The limiting side plate is provided in two, and the two limiting side plates are arranged at intervals along the second direction. The two limiting side plates are arranged correspondingly to the two clamping side plates.
