Embodiment 1

[0036] The present embodiment proposes a kind of fast hardening non-shrinkage concrete, and the fast hardening non-shrinkage concrete of preparation per cubic meter volume comprises the following components:

[0037]240kg of ordinary Portland cement, 60kg of sulphoaluminate cement, 30kg of expansion agent, 40kg of fly ash, 40kg of slag powder, 280kg of river sand, 420kg of machine-made sand, 450kg of crushed stone with a diameter of 5-10mm, and crushed stone with a diameter of 12-20mm Stone 680kg, polycarboxylate high-performance superplasticizer 5.6kg and water 165kg.

[0038] Do the test in the following table, in which, ultra-fine sand is gravel with a diameter of 5-10mm; machine-made sand is gravel with a diameter of 12-20mm; 25% ultra-fine sand means that the mass ratio of each mixing is 25%.

[0039]

[0040]

[0041] The mixture of 5-10mm crushed stones and 12mm-20mm crushed stones is mixed sand. In order to avoid excessive shrinkage ratio after solidification cau...

Embodiment 2

[0043] This embodiment proposes a rapid-hardening non-shrinkage concrete production equipment, including: a mixing device for mixing the components of the rapid-hardening non-shrinkage concrete in Example 1.

[0044] Such as figure 1 As shown, in order to design a mixing device with a simple structure and realize automatic identification of crushed stones with a diameter of 5-10mm and crushed stones with a diameter of 12-20mm, the mixing device includes:

[0045] mixing box 1;

[0046] The feeding assembly includes a material receiving funnel 21, the material receiving funnel 21 stands on the top of the mixing box 1 through a mounting frame, a filter screen 22 is installed in the material receiving funnel 21, the filter screen 22 includes a mounting frame, and the mounting frame is installed on the material receiving On the funnel 21 inner walls, the installation frame is closed by a mesh body, and the mesh body can pass through crushed stones with a diameter of 5-10mm. The i...

Abstract

The present invention provides a rapid hardening non-shrinkage concrete production equipment and a production method thereof, wherein the rapid hardening non-shrinkage concrete production equipment includes: a mixing device, the mixing device includes: a mixing box; a feeding assembly, which includes a material receiving funnel A filter screen is installed in the material funnel, and the mesh body can pass through the gravel with a diameter of 5-10mm; a discharge cover connected to the first discharge hole is installed on the outer wall of the material receiving funnel, and the bottom end of the discharge cover is connected to the The top of the main pipe, the bottom end of the main pipe is connected with the first branch pipe and the second branch pipe used to communicate with the outer wall material receiver, and a switching valve is arranged at the connection between the main pipe and the first branch pipe and the second branch pipe; the first weighing component; the second branch pipe Weigh the components. The rapid-hardening non-shrinkage concrete production equipment and its production method solve the problem that in the prior art, the crushed stones with a diameter of 5-10mm and the crushed stones with a diameter of 12-20mm cannot be automatically identified, and the wrong configuration components lead to poor quality of fast-hardened non-shrinkage concrete products. low problem.

Description

technical field [0001] The invention relates to concrete and production equipment thereof, in particular to a production equipment and production method of rapid hardening non-shrinkage concrete. Background technique [0002] Chinese patent discloses a concrete with application number 201610550161.7, the concrete is composed of cement, sand, stones, water, water reducer, phenolic fiber and montmorillonite; wherein, relative to 1000kg of stones, the cement The consumption of the sand is 500-700kg, the consumption of the sand is 350-450kg, the consumption of the water is 160-280kg, the consumption of the water reducer is 3-6kg, the consumption of the phenolic fiber is 8-22kg, the The consumption of montmorillonite is 60-85kg. Although the concrete improves the impact resistance to a certain extent, the disadvantages of the concrete are: [0003] No gravel is added, resulting in a larger shrinkage of the concrete after solidification than before, which is not conducive to gra...
