Embodiment 1

[0047] Embodiment 1: A kind of cement mixture, each component and its corresponding parts by weight are as shown in Table 1, and are prepared through the following steps:

[0048] Step 1, put cement clinker, fly ash, mineral powder, gypsum and silicon powder of corresponding parts by weight into the mixing tank for mixing, the stirring speed is 800rpm, and the stirring time is 30min to obtain the mixed material;

[0049] Step 2, mixing and stirring the bamboo fiber filaments and expanded perlite powder in corresponding parts by weight, the stirring speed is 600rpm, and the stirring time is 40min, to obtain the filling masterbatch;

[0050] Step 3, mixing and stirring the above-mentioned mixture and the filler masterbatch evenly at a stirring speed of 500 rpm and a stirring time of 60 minutes to obtain coarse cement material;

[0051] Step 4, the above-mentioned cement coarse material is transported into the roller press through the conveyor belt, and crushed under the action o...

Embodiment 2-8

[0053] Example 2-8: A cement mixture, the difference from Example 1 is that each component and its corresponding parts by weight are shown in Table 1.

[0054] Each component and parts by weight thereof in table 1 embodiment 1-8

[0055]

[0056]

Embodiment 9

[0057] Embodiment 9: a kind of cement mixture, the difference with embodiment 1 is that described bamboo fiber silk carries out pretreatment, and the step of pretreatment is as follows:

[0058] Step a, place the bamboo fiber silk of the corresponding mass fraction in the alkaline solution, and add the polypropylene fiber of the corresponding mass fraction, stir and mix together, stir for 30min, the whole process temperature is controlled at 30°C, and the stirring speed is 500rpm;

[0059] Step b, adding polyvinyl alcohol in corresponding parts by mass to the alkaline solution in step a, and performing ultrasonic treatment;

[0060] In step c, the alkaline solution in step b is removed, and the bamboo fiber filaments are dried to obtain pretreated bamboo fiber filaments.

Abstract

The invention discloses a cement mixture and a preparation process thereof, relates to the technical field of cement production, and solves the problem of poor strength of cement poured into concrete at a later stage due to poor bonding of components in cement raw materials. A cement mixture, characterized in that it comprises the following components in parts by weight: 50-70 parts of cement clinker; 15-25 parts of fly ash; 9-14 parts of mineral powder; 2-4 parts of gypsum; 1.2-2 parts; bamboo fiber silk 0.8-2 parts; expanded perlite powder 0.8-2 parts. The concrete poured by the invention has extremely high strength, is not easy to break, has simple preparation process steps, is convenient to operate, and can also improve the compactness of the concrete, so that the strength of the concrete is improved.

Description

technical field [0001] The invention relates to the technical field of cement production, more specifically, it relates to a cement mixture and a preparation process thereof. Background technique [0002] Cement refers to powdery hydraulic inorganic gelling materials. It can become a slurry after adding water and stirring, and can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. 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. [0003] A Chinese invention patent with the publication number CN106630699A discloses a kind of cement, which is made of the following raw materials in parts by weight: 8-10 parts of cement raw material, 4-6 parts of industrial waste residue, 1-2 parts of pigment, 2 par...
