Embodiment 1

[0027] A production method for making concrete by using mine waste rock, the concrete is prepared from the following raw materials in parts by weight:

[0028] 1500 parts of cement, 150 parts of fly ash, 400 parts of mine waste rock powder, 1500 parts of mine waste rock, 3500 parts of mine waste sand, 900 parts of water, 30 parts of water reducing agent, 5 parts of polyacrylamide;

[0029] Described production method comprises the following steps as follows:

[0030] (1) The mine waste rock is crushed by a pulverizer and sieved in turn to obtain mine waste rock powder with a particle size of 0.1mm-1mm, mine waste rock sand with a particle size of 1mm-10mm, and mine waste rock with a particle size of 10mm-30mm. Stones; Mine waste rock with a particle size greater than 30mm is sent back to the crusher (such as an impact crusher) for further crushing;

[0031] (2) Mix the crushed mine waste rock powder, mine waste stones and mine waste sand in step (1) with fly ash in proportion...

Embodiment 2

[0037] Such as figure 1 As shown, a production system for making concrete by using mine waste rock includes a pulverizer, and the pulverizer is connected with the first screening machine, the second screening machine, the third screening machine and the mixer in turn, and the third screening machine It is also connected to the pulverizer, and the mixer powder is also connected to the fly ash storage tank, cement storage tank, water storage tank, water reducer storage tank and polyacrylamide storage tank through pipelines;

[0038] Wherein, the screening particle diameter of the first screening machine is 0.1mm-1mm, the screening particle diameter of the second screening machine is 1mm-10mm, and the screening particle diameter of the third screening machine is 10mm-30mm.

[0039] In each embodiment of the present invention, the chemical materials used are the materials used in the production in this field, all can be obtained from the market, and will not have an impact on the ...

Abstract

A producing method for producing concrete from mine waste ore and a producing system are disclosed. The producing method includes: smashing the mine waste ore through a smasher, sieving in order, mixing smashed mine waste or powder, mine waste cobbles and mine waste stone sand with coal ash according to a ratio, stirring, adding cement, stirring uniformly, adding a water reducer and polyacrylamide, adding water, and stirring. The producing system comprises the smasher. The smasher, a first sieving machine, a second sieving machine, a third sieving machine and a stirrer are connected in sequence. The third sieving machine is connected to the smasher. The producing method and the producing system are advantaged by reducing the total binding material in the concrete, improving peaceability and pumpability of the concrete, increasing the using amount of the mine waste ore in the concrete, effectively reducing pollutions in a mine area, reducing the risk of mud-rock flows, alleviating grassland desertification processes, and protecting the environment.

Description

[0001] technical field [0002] The invention relates to a concrete production method, in particular to a production method and a production system for making concrete by utilizing mine waste rock, and belongs to the field of concrete production. Background technique [0003] Mine waste rock can be used as a common raw material in concrete production. However, there are some problems in the application technology of mine waste rock in concrete in the past: such as poor grading of mine waste rock, low replacement rate, high amount of total cementitious materials in concrete, poor workability and pumpability of concrete, etc. Contents of the invention [0004] In order to solve the above-mentioned problems, the present invention designs a production method and production system of using mine waste rocks to make concrete, which reduces the total cementitious materials of concrete, improves the workability and pumpability of concrete, and increases the yield of mine waste rock...
