Anti-crack concrete and preparation method thereof as well as anti-crack assembly type prefabricated component composite floor slab and preparation method thereof
The invention relates to the technical field of composite floor slabs, in particular to anti-crack concrete, a preparation method thereof, an anti-crack assembly type prefabricated component compositefloor slab and a preparation method thereof. The anti-crack concrete provided by the invention is prepared from the following preparation raw materials in parts by weight: 270 to 300 parts of cement,70 to 100 parts of fly ash, 850 to 900 parts of sand, 1000 to 1150 parts of stone, 5.5 to 6.2 parts of a water reducing agent, 0.8 to 1.0 part of a waterproof agent and 160 to 170 parts of water. Theanti-crack effect of the concrete can be improved through the matching effect of all the components and the dosage.
