Concrete additive is an admixture added during concrete mixing. It is mainly used to improve the performance of concrete. From the point of addition ratio of admixture, generally not more than 5%. For all kinds of concrete admixtures, the role of the precipitant is mainly to reduce the water consumption, increase the density and elasticity of the concrete, and make the concrete durable. The air entraining agent can improve the solubility of the concrete, and reduce the internal crack of the concrete by improving the internal structure of the concrete, so that the concrete can improve its antifreeze and impermeability. For concrete with high frost resistance requirements, it is possible to properly perform bleed air or a mixture of precipitation additives.

Concrete admixtures shall be selected carefully as per the specifications and shall be used as recommended by the manufacturer or by lab testing report. The quantity of admixtures to be used for specific application of admixtures are recommended by the manufacturers. For use in large construction projects, the quantity of the admixture to be used shall be obtained from tests reports for concrete mixed with admixtures at various percentage admixtures use. These tests are conducted to understand the behaviour of admixtures on the desired quality and strength of concrete at different quantity of admixtures used. Thus, the optimum quantity of admixtures can be selected for specific application based on results.

Set retarding concrete admixtures are used to delay the chemical reaction that takes place when the concrete starts the setting process. These types of concrete admixtures are commonly used to reduce the effect of high temperatures that could produce a faster initial setting of concrete. Set retarding admixtures are used in concrete pavement construction, allowing more time for finishing concrete pavements, reducing additional costs to place a new concrete batch plant on the job site and helps eliminate cold joints in concrete. Retarders can also be used to resist cracking due to form deflection that can occur when horizontal slabs are placed in sections. Most retarders also function as water reducers and may entrain some air in concrete.

Commercial concrete, especially high-strength and high-performance concrete with large flowability and low water-to-cement ratio, has an excessive loss of slump due to poor adaptability of admixtures and cement during transportation and construction. It not only affects the construction of concrete, construction quality, and even the inability to pump construction, but also will affect the quality of hardened concrete, thus proposed a variety of methods to improve the admixture and cement adaptability to control the concrete slump loss.

Safe and efficient use of polycarboxylate superplasticizer must pay attention to the some problems, like the dosage and the proportion of the materials and avoid to use polycarboxylate superplasticizer with some admixtures, do more research on the polycarboxylate superplastcizer application is a must.

Haisen Chemical is an professional manufacturer of cement and concrete admixtures, including polyether monomers and isopropanolamine series. The pricing of these chemicals are affected by the EO/PO supply and price change.

Concrete slump loss over time control methods include: retardation control method, modified control method, particle isolation method and other methods. Haisen chemical wish to communicate with you to discuss the method to get a good concrete mixtures with good workability.
