| titleOfInvention | C60 pump concrete and preparation method thereof |
| abstract | The invention discloses C60 pump concrete and a preparation method thereof, and the technical scheme is that the C60 pump concrete comprises the following components in parts by weight: 420 parts of cement, 130 parts of admixture, 150 parts of fine aggregate, 690 parts of fine aggregate, 980 parts of coarse aggregate, 8-10 parts of admixture and 170 parts of water; the fine aggregate is formed by mixing river sand and machine-made sand in a weight ratio of 3: 7; the fineness modulus of the river sand is 0.9-1.1, and the fineness modulus of the machine-made sand is 2.8-2.9; the coarse aggregate is formed by mixing cobbles and small cobbles according to the weight ratio of 6.5: 3.5; the particle size of the cobble is 10-20mm, and the mud content is less than 0.5%; the particle diameter of the small pebbles is 5-10mm, and the mud content is less than 0.6 percent. The pumping concrete has the advantages of high compressive strength, good workability and high pumping height. |
