Example Embodiment
[0042] Example 1: A high-strength self-compacting concrete. The components and their corresponding parts by weight are shown in Table 1, and are prepared by the following steps:
[0043] Step 1: Stir and mix the corresponding parts by weight of medium sand, crushed stone raw materials, fly ash, cement raw materials, mineral powder and quartz powder at a stirring speed of 40 rpm and a stirring time of 25 minutes to obtain a mixture;
[0044] Step 2: Mix the water reducing agent and water in a mixing station, and continue to stir at a stirring speed of 15 rpm, stirring for 4 minutes, to obtain a mixed solution;
[0045] Step 3: Stir and mix the mixture with the mixture, continue stirring for 8 minutes at a stirring speed of 35 rpm, add the corresponding parts by weight of magnesium fluorosilicate, and continue stirring for 4 minutes to obtain high-strength self-compacting concrete.
[0046] Note: In the above steps, the raw materials of crushed stone should be selected with two grades: 5...
Example Embodiment
[0047] Example 2: A high-strength self-compacting concrete, which is different from Example 1 in that it is prepared through the following steps:
[0048] Step 1: Stir and mix the corresponding parts by weight of medium sand, gravel raw materials, fly ash, cement raw materials, mineral powder and quartz powder at a stirring speed of 30 rpm and a stirring time of 30 minutes to obtain a mixture;
[0049] Step 2: Mix the water reducing agent and water in a mixing station, and continue to stir at a stirring speed of 10 rpm and stir for 5 minutes to obtain a mixed solution;
[0050] Step 3: Stir and mix the mixture with the mixture, continue stirring for 10 minutes at a stirring speed of 30 rpm, add the corresponding parts by weight of magnesium fluorosilicate, and continue stirring for 5 minutes to obtain high-strength self-compacting concrete.
Example Embodiment
[0051] Example 3: A high-strength self-compacting concrete, which is different from Example 1 in that it is prepared through the following steps:
[0052] Step 1: Stir and mix the corresponding parts by weight of medium sand, gravel raw materials, fly ash, cement raw materials, mineral powder and quartz powder at a stirring speed of 50 rpm and a stirring time of 20 minutes to obtain a mixture;
[0053] Step 2: Mix the water reducing agent and water in a mixing station, and continue to stir at a stirring speed of 20 rpm for 3 minutes to obtain a mixed solution;
[0054] Step 3: Stir and mix the mixture with the mixture, continue stirring for 6 minutes at a stirring speed of 40 rpm, add the corresponding parts by weight of magnesium fluorosilicate, and continue stirring for 3 minutes to obtain high-strength self-compacting concrete.
