Self-compacting expansive concrete and preparation method thereof
The invention discloses self-compacting expansive concrete and a preparation method thereof. The self-compacting expansive concrete is prepared from the following raw materials in parts by weight: 420-480 parts of cement; 50 to 70 parts of fly ash; 720 to 800 parts of fine aggregate; 950 to 1050 parts of coarse aggregate; 120 to 200 parts of water; 8 to 16 parts of a water reducing agent; 32 to 40 parts of an expanding agent; the expanding agent comprises two or more of calcium aluminosilicate, calcium sulphoaluminate and magnesium oxide. The concrete has the effect of improving the flowability of the concrete.
