Embodiment 2

[0062] A method for preparing aggregate composite cemented concrete for road repair, comprising the following steps:

[0063] Step 1: Selection of raw materials: 150-250 parts of cement, 50-100 parts of asphalt, 100-150 parts of 100-mesh fine sand, 20-30 parts of improved additives, 5-10 parts of bentonite grafted hydrophobic agent, 1-10 parts of activated kaolin parts, 2-6 parts of basalt fiber;

[0064] Step 2: Add the raw materials of Step 1 into the mixing shell 32, and drive the rolling gear 333 on the rotating shaft 331 to rotate through the rotation of the two first driving motors 33 provided, and drive the rolling gear 333 under the action of the driving force The rotation is convenient to the rack 34 on the mixing housing 32 and the slide rail 341 are rolled and connected, so that the aggregate of the road repair inside the mixing housing 32 is mixed and stirred;

[0065] Then, the rotation of the first drive motor 33 drives the stirring blade 37 to mix and stir the ...

Embodiment 3

[0076] Same as embodiment 2 concrete preparation method;

[0077]The preparation method of the improved additive is:

[0078] S1: Mix rare earth lanthanum chloride with a mass fraction of 60% and polyethylene glycol emulsifier in a weight ratio of 1:2, then stir at a speed of 150r / min for 25min, and then add nano-calcium carbonate with a mass fraction of 15 solution, continue to stir for 15 minutes, and the stirring is completed to obtain the amphoteric solution;

[0079] S2: Feed the nano-silica into the sodium alginate solution and stir at a low speed for 15 minutes at a stirring speed of 150r / min to prepare a nano-silica solution; wherein the sodium alginate solution is sodium alginate and hydrochloric acid at a weight ratio of 1 :3 mixed and prepared;

[0080] S3: Mix the amphoteric solution and the nano-silica solution at a weight ratio of 1:3, and then carry out ultrasonic dispersion. The ultrasonic power is 300W, and the ultrasonic time is 25 minutes. After the ultras...

Abstract

The invention discloses a preparation device and preparation method of aggregate composite cemented concrete for road repairing. The preparation device comprises a first fixing frame, a second fixing frame is fixedly mounted at the top of the first fixing frame, a mixing and stirring mechanism is fixedly mounted at the top of the second fixing frame, and a crushing mechanism is fixedly mounted at the top of the first fixing frame. The preparation method comprises the following steps: selecting the following raw materials: 150-250 parts of cement, 50-100 parts of asphalt, 100-150 parts of 100-mesh fine sand, 20-30 parts of an improved additive, 5-10 parts of a bentonite grafted water repellent agent, 1-10 parts of active kaolin and 2-6 parts of basalt fiber. A second driving motor rotates to drive crushing blocks on the outer side of a shaft column to rotate in a crossed mode, so that the crushing blocks crush stones, aggregate raw materials for road repairing are conveniently crushed through the second driving motor, aggregate composite cemented concrete raw materials are conveniently and rapidly stirred and crushed, and meanwhile, the raw materials can be conveniently and quickly processed.

Description

technical field [0001] The invention relates to the technical field of road repairs, in particular to an aggregate composite cemented concrete preparation device and a preparation method for road repairs. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. . Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. [0003] The existing mechanical equipment used for road repair has a simple structure, and the concrete raw materials cannot be processed thoroughly during the processing process, thereby affecting the effect of road repair. At the same time, the raw materials...
