Embodiment 1

[0052] Preparation of concrete admixtures

[0053] The chemical structural formula of monomer (I) is:

[0054]

[0055] where R 1 is methyl, R 2 is an ethyl group, n is 5, and this monomer can be prepared by esterifying polyethylene glycol and methacrylic acid according to a conventional esterification method, and then reacting the esterification product with ethoxychloride according to a conventional elimination reaction, or it can be Commercially purchased directly from Aldrich Corporation;

[0056] The chemical structural formula of monomer (II) is:

[0057] This monomer is also commercially available from Aldrich;

[0058] Adopt emulsion polymerization method, add 80g monomer (I) and 13g monomer (II) and 200mL deionized water in the 500mL round-bottomed flask that has mechanical stirrer, nitrogen is led under stirring, then add 0.1g ammonium persulfate as The initiator is heated up to the polymerization temperature, the polymerization temperature is 80°C, and the...

Embodiment 2

[0060] Prepare concrete by mixing the following components: 50 parts by weight of road milling waste, 10 parts by weight of iron tailings, 20 parts by weight of cement, 0.03 parts by weight of the admixture prepared in Example 1, and 30 parts of water; The milling waste is the graded aggregate made from the asphalt concrete road milling waste; the graded aggregate made from the asphalt concrete road milling waste is obtained through the following steps: (1) to the 107 National Road Renovate the asphalt concrete road surface and carry out milling. The thickness of the first layer of milling is 5cm, and the thickness of the second layer of milling is 10cm; After the particles are crushed, sieve again to obtain particles of 10-30mm, which are recorded as particle A; the particles smaller than 10mm are collected for later use, and the particles are recorded as particle B; (3) crush the second layer of milling material, and sieve Particles of 10-20mm in diameter were collected sepa...

Abstract

The invention provides a low-cost concrete and a production process thereof. The concrete is prepared from, by weight, 40-70 parts of pavement milling scraps, 5-15 parts of iron tailings, 15-30 parts of cement, 0.02-0.2 part of additives and 10-50 parts of water. The milling scraps refer to graded aggregate produced from milling scraps of asphalt concrete pavement. According to the production process, both the pavement milling scraps and the iron tailings are recycled completely and the concrete meeting requirements is obtained with low production cost.

Description

technical field [0001] The invention relates to a concrete production process, in particular to a low-cost concrete production process, more particularly to a low-cost concrete containing iron tailings and road surface milling materials and a production process thereof. Background technique [0002] With the increasing number of ready-made concrete in the market, the competition in the ready-made concrete market is becoming increasingly fierce, and the high-profit era of ready-made concrete enterprises has long passed. Faced with this situation, only by reducing the production cost of commercial concrete can the competitiveness of commercial concrete be increased in the market. How to control the cost reasonably and effectively is the key to the survival and development of commercial concrete manufacturers. [0003] In addition, in recent years, with the rapid development of mines, the amount of mine tailings has continued to increase. According to incomplete statistics, ab...
