Concrete pumping agent and production process thereof

Abstract

The invention discloses a concrete pumping agent and a production process thereof. The concrete pumping agent comprises the following raw materials in parts by weight: 5-10 parts of modified naphthalene sulfonated formaldehyde condensates, 4-8 parts of hexose dicalcium, 6-11 parts of methylcellulose, 3-7 parts of gleditsia sinensis infusion, 4-9 parts of sodium sulfate, 2-8 parts of sodium gluconate, 10-15 parts of sodium hexametaphosphate, 5-11 parts of polyphosphates, 12-17 parts of triethanolamine, 7-11 parts of nitrate, 3-7 parts of ethylene glycol, 2-8 parts of nitrite, 10-20 parts of sulfamate, 20-25 parts of aliphatic hydroxyl sulfonate and 8-15 parts of a naphthalene water reducer. The concrete pumping agent has the properties of water reducing, slump loss resistance, pumping assistance, coagulation delaying, early strength, freeze protection and the like, can be widely applied to production of commercial concrete and commercial mortar and is simple in preparation method.

Description

technical field [0001] The invention relates to the field of pumping agents, in particular to a pumping agent for concrete and a production process thereof. Background technique [0002] Pumping agent, also known as concrete pumping agent. It is an admixture to improve the pumping performance of concrete. It has excellent water-reducing and strengthening effects and retarding and plastic-retaining properties. At present, commercial concrete is mostly used in urban buildings. In order to ensure the workability and fluidity of concrete during the pumping process, Concrete needs to add pumping agent. With the advancement of science and technology, the performance of the existing concrete pumping agent can no longer meet people's needs. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a pumping agent for concrete and a production process thereof. [0004] A pumping agent for concrete prop...
