Background
The concrete additive is a chemical substance which is mixed in the process of stirring concrete and accounts for less than 5% of the mass of cement and can obviously improve the performance of the concrete. The concrete admixture has the characteristics of more varieties, small mixing amount, large influence on the performance of concrete, low investment, quick response and remarkable technical and economic benefits. Along with the continuous progress of science and technology, the additive is increasingly applied, the additive becomes an important component of concrete except a basic component, the additive has a certain improvement effect on the carbonization resistance of the concrete, and a certain linear relation exists between the carbonization depth and the porosity of the concrete; the additive has great influence on the frost resistance of concrete, the concrete doped with the air-entraining water reducer has better frost resistance, and the single-doped early strength agent has no improvement effect on the frost resistance of concrete. The concrete admixture comprises retarder, expanding agent and water reducing agent, wherein the water reducing agent is used for releasing the wrapped water. The hydrophobic group of the water reducer is directionally adsorbed on the surface of cement particles, and the hydrophilic group points to the aqueous solution to form the single-molecule adsorption film. Because of directional adsorption, cement particles have the same charge, electrostatic repulsion is generated, a cement water body system is in a stable suspension state, a flocculation structure formed at the early stage of cement water addition is broken down, and free water is released, so that the purposes of reducing water and keeping required workability are achieved.
After the concrete water reducer is added into concrete, sodium aluminate and sodium carbonate in main components of the concrete water reducer react with gypsum in cement in alkaline solution to form sodium sulfate, so that the gypsum loses the original retarding effect, calcium aluminate minerals are quickly hydrated, and hydrated product crystals of the calcium aluminate minerals are separated out from the solution. Thereby rapidly setting the cement concrete. And many polycarboxylate water reducers have low pH values, for example, the polycarboxylate water reducers are difficult to adapt to high-alkaline cement when being used together with acid retarders such as citric acid. After the acid additive is mixed into high-alkali cement, acid-base neutralization exothermic reaction can be quickly generated, the temperature is rapidly increased, the cement is rapidly hydrated, and a large amount of hydration heat is released to generate vicious circle, so that the prepared concrete has poor fluidity. Meanwhile, a large amount of heat is released in the early stage of the reaction system, so that high temperature is generated in the reaction kettle, the air pressure is increased instantaneously, potential safety hazards are easy to cause, when the temperature in the reaction kettle or the stirring tank is increased, hot kettle cooling materials are formed when the additive is heated continuously, the temperature difference between the materials and the kettle wall is increased, internal stress is generated due to the large temperature difference, and the service life of equipment is influenced.
