Abstract
Description
technical field
[0001] The invention relates to an integrated device for testing and evaluating the properties of concrete materials. Background technique
[0002] The workability test and evaluation of concrete is a very complicated problem. At present, the slump cylinder method is widely used [1οΌ2] ([1] P. Kumar Mehta, Paulo J.M. Monteiro. CONCRETE: microstructure, properties and materials [M, third edition]. The McGraw-Hill Companies, New York, 2006; [2] Zhou Shiqiong. Civil engineering materials [M]. Beijing : China Railway Press, 2004), this method is simple and convenient, but it must be combined with subjective experience to reflect the rheological properties of concrete. Due to its very high workability requirements, self-compacting concrete includes three aspects: filling, segregation resistance and gap passage. [3] ([3] Hajime Okamura and Masahiro Ouchi.
