Problems solved by technology

[0004] With the rapid development of society today, high-rise buildings are built on the ground. The construction industry has a great demand for cement. At the same time, the performance requirements for cement are also gradually increasing. The current speed of cement setting and drying is average, which affects the progress of construction projects. Therefore, there is a need for a cement that can set quickly, and at the same time, the performance can be guaranteed

Embodiment 1

[0025] A preparation method of quick-drying cement, comprising the following steps:

[0026] 1): Mix clay, yellow sand and water until it becomes a mixture;

[0027] 2): add coal cinder, fly ash and blast furnace slag again, grind and stir together, weight ratio is coal cinder 15, fly ash 20, blast furnace slag 15;

[0028] 3): the mixed substance after being fully mixed is sent into a calcining kiln for calcining, and the calcining time is 8 hours;

[0029] 4): Let the calcined mixture stand still, cool naturally for 5 hours, and then grind it into powder;

[0030] 5): Mix the powdered mixture into water and stir it into cement.

Embodiment 2

[0032] A preparation method of quick-drying cement, comprising the following steps:

[0033] 1): Mix clay, yellow sand and water until it becomes a mixture;

[0034] 2): add coal cinder, fly ash and blast furnace slag again, grind and stir together, weight ratio is coal cinder 18, fly ash 30, blast furnace slag 20;

[0035] 3): the mixed substance after being fully mixed is sent into a calcining kiln for calcining, and the calcining time is 9 hours;

[0036] 4): Let the calcined mixture stand still, cool naturally for 5 hours, and then grind it into powder;

[0037] 5): Mix the powdered mixture into water and stir it into cement.

Embodiment 3

[0039] A preparation method of quick-drying cement, comprising the following steps:

[0040] 1): Mix clay, yellow sand and water until it becomes a mixture;

[0041] 2): add coal cinder, fly ash and blast furnace slag again, grind and stir jointly, weight ratio is coal cinder 20, fly ash 35, blast furnace slag 25;

[0042] 3): the mixed substance after being fully mixed is sent into a calcining kiln for calcining, and the calcining time is 10 hours;

[0043] 4): Let the calcined mixture stand still, cool naturally for 5 hours, and then grind it into powder;

[0044] 5): Mix the powdered mixture into water and stir it into cement.

[0045] By above-mentioned embodiment, through test comparison, the coagulation speed of embodiment 3 is the fastest, second is embodiment 2, is embodiment 1 at last, it can be concluded that embodiment 3 is the best effect, but embodiment 2 and embodiment 1 are only Relative to Example 3, so Example 2 and Example 1 are still faster than the setti...

Abstract

The invention relates to the technical field of cement making, in particular to a method for making quick-drying cement, which comprises the following steps: 1) mixing clay, yellow sand and water andstirring until the clay, the yellow sand and water are mixed; 2) adding coal cinder, fly ash and blast furnace slag, grinding and stirring together, and that weight ratio of the coal cinder, the fly ash and the blast furnace slag being 15-20:20-35:15-25; 3) sending the fully mixed mixture into a calcining kiln for calcining, and the calcining time being 8-10 hours; 4) subjecting the calcined mixture to standing, naturally cooling for 5 hours, and then grinding into powder; 5): adding water into the mixture which is ground into powder and stirring to form cement. The invention solves the shortcoming of the traditional cement such as slow setting and drying, makes the mixture of the cement contact with the air to quickly set and dry by using chemical reaction, does not affect the strength performance of the cement at the same time, can add different substances according to different requirements to carry out cement mixing, and ensures the applicability and universality of various projects.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a production method of quick-drying cement. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. [0003] In the early years the mixture of lime and volcanic ash is very similar to lime pozzolanic cement, use it to glue concrete which made of crushed stone. After hardening, the cement not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it is widely used in civil engineering, water conservancy, national defense and other projects. [0004] With the rapid development of society today, high-rise buildings are built on the ground. The construction industry has a great deman...
