High-ductility concrete as well as preparation method and equipment thereof

[0056] A kind of high ductility concrete, the parts by weight of each material are with reference to table 2, comprise the following steps:

[0057] Step 1: Add cement, quartz sand, fly ash, coarse aggregate, fine aggregate, polyvinyl alcohol fiber and coumarone resin to the mixer for mixing according to the mass, at a speed of 190r / min, stir for 7min, and heat to 90°C, mix evenly to obtain the first mixture;

[0058] Step 2: Add the water reducer and water to the first mixture of the mixer according to the mass, and mix at a speed of 360r / min, stir for 30s, and mix evenly to obtain the second mixture;

[0059] Step 3: Add permanganate to the second mixture according to the mass, rotate at 180r / min, stir for 1min, mix well, and heat to 85°C to obtain the third mixture;

[0060] Step 4: Use a mixer to continue stirring the third mixture at a speed of 80 r / min, and stir for 2 hours to obtain high ductility concrete.

[0062] Step 1: Add cement, quartz sand, fly ash, coarse aggregate, fine aggregate, polyvinyl alcohol fiber and coumarone resin to the mixer for mixing according to the mass, at a speed of 190r / min, stir for 5min, and heat to 80°C, mix evenly to obtain the first mixture;

[0063] Step 2: Add the water reducer and water into the mixer according to the mass and mix them at a speed of 360r / min, stir for 20s, and mix evenly to obtain the second mixture;

[0064] Step 3: Add permanganate to the second mixture according to the mass, rotate at a speed of 180r / min, stir for 2min, mix well, and heat to 110°C to obtain the third mixture;

[0065] Step 4: Use a mixer to continue stirring the third mixture at a speed of 80 r / min, and stir for 1 hour to obtain high ductility concrete.

[0067] Step 1: Add cement, quartz sand, fly ash, coarse aggregate, fine aggregate, polyvinyl alcohol fiber and coumarone resin to the mixer for mixing according to the mass, at a speed of 190r / min, stir for 6.5min, and heat to 88°C, mix evenly to obtain the first mixture;

[0068] Step 2: Add the water reducer and water into the mixer according to the mass and mix them at a speed of 360r / min, stir for 25s, and mix evenly to obtain the second mixture;

[0069] Step 3: Add permanganate to the second mixture according to the mass, rotate at 180r / min, stir for 1.5min, mix well, and heat to 95°C to obtain the third mixture;

[0070] Step 4: Use a mixer to continue stirring the third mixture at a speed of 80 r / min, and stir for 1.5 hours to obtain high ductility concrete.

[0071] In Examples 1-3, the particle size range of the coarse aggregate is 6.5-7.5mm, 8.5-12.5mm and 9.5-10.5mm.

[0072] In Examples 1-3, the particle size range of the fine aggregate is 0.5-2mm, 1.4-2.4m
