Embodiment 1

[0026] A concrete pumping agent is prepared according to the following weight percentages: 37.5% polyacrylamide and 62.5% sodium sulfate.

[0027] The polyacrylamide includes 45% anionic polyacrylamide with a molecular weight of 20 million, 30% anionic polyacrylamide with a molecular weight of 12 million, and 25% nonionic polyacrylamide with a molecular weight of 8 million.

[0028] Weigh the raw materials in proportion and mix them evenly to obtain the pump agent; when in use, slowly add the pump agent to 70 times the water, stir at room temperature for 10 minutes, and when the solution becomes viscous, the solution becomes viscous Yes; pour the viscous lubricant solution into the concrete delivery pump hopper and pump the lubricant solution. The first 50 meters of the pump tube near the inlet of the pump tube use 175g of the pumping agent; for every 50 meters of increase in the length of the pump tube, the amount of the pumping agent increases by 250g.

Embodiment 2

[0030] Basically the same as Example 1, the difference is:

[0031] A concrete pumping agent is prepared according to the following weight percentages: 25% polyacrylamide and 75% sodium sulfate.

[0032] The polyacrylamide includes 60% anionic polyacrylamide with a molecular weight of 20 million, 15% anionic polyacrylamide with a molecular weight of 12 million, and 25% nonionic polyacrylamide with a molecular weight of 8 million.

Embodiment 3

[0034] Basically the same as Example 1, the difference is:

[0035] A concrete pumping agent is prepared according to the following weight percentages: 50% polyacrylamide and 50% sodium sulfate.

[0036] The polyacrylamide includes 30% anionic polyacrylamide with a molecular weight of 20 million, 45% anionic polyacrylamide with a molecular weight of 12 million, and 25% nonionic polyacrylamide with a molecular weight of 8 million.

Abstract

The invention discloses a concrete pump moisturizing agent and a using method thereof. The concrete pump moisturizing agent is prepared from the following raw materials in percentages by weight: 25-50% of polyacrylamide and 50-75% of sodium sulfate. Components of raw materials of the pump moisturizing agent are easily obtained, a production process is simple and convenient, the production cost islow, water solubility is good, construction is facilitated, adaptability to concrete and mortar is good, adverse effects on concrete do not exist, construction operability of concrete pumping can be greatly improved, and meanwhile, the concrete pump moisturizing agent is energy-saving and environmentally friendly, and has good industrial prospect.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a concrete pumping agent and its application method. Background technique [0002] Concrete is a commonly used building material, and it is mainly poured by pumping technology during on-site construction. Before pumping concrete, the pump truck and pipeline must be wetted and lubricated to reduce the frictional resistance through the pipeline during concrete pumping and ensure smooth pumping. [0003] The traditional pumping method is mainly to use pumping mortar. In the past few decades, the ready-mixed concrete industry all over the country has been using water and mortar to moisten the pipes. This requires concrete companies to invest a lot of manpower, material resources, and financial resources for production. First, in terms of raw materials, at present, when cement, river sand, and production water resources are in short supply, it will cause a lot of waste of resources ...
