Description

technical field

[0001] The invention relates to a concrete mold, in particular to a concrete mold developed for single-sided salt freezing experiments. Background technique

[0002] In recent years, with the application of high-strength concrete in some special buildings, research on the properties of high-strength concrete has attracted more attention. At present, due to the special size of the test piece required for the single-sided freeze-thaw test of high-strength concrete, the strength of the concrete is quickly formed, and the demoulding is difficult, which makes the process of supporting the test piece time-consuming and laborious.

[0003] In cold regions, roads, bridges, ocean platforms and high-rise buildings are severely damaged by freezing damage. Concrete freezing damage is undoubtedly one of the most important reasons for premature failure of roads and bridges. The northern region of our country, especially the great northwest of our country under constructio...
