Mix Proportion Design and Basic Mechanical Properties Experiment of Self-Compacting Lightweight Concrete

In order to get the requirements of workability and basic mechanical properties of self-compacting lightweight aggregate concrete, fixed sand and gravel volume method and overall calculation method are used to mix design. Slump flow and L-box tests are used to test the workability of self-compacting lightweight aggregate concrete, the strength increasing and the final value are tested by compression tests. For contrast, a set of common concrete is selected to compare the differences of efficiency. Tests indicated that the 5 groups of self-compacting lightweight aggregate concrete can get the requirements of workability and compressive strength, and the structure efficiency can be significantly higher than normal concrete.
