  • Progress and development prospects of polycarboxylate superplasticizer polyether macromonomer

    With the development of concrete technology, the requirements for polycarboxylate superplasticizers are more refined, not limited to the basic performance advantages such as water reduction rate and moisture retention. Since the polymerization of polycarboxylate superplasticizer is designable, polycarboxylate water reducing agent with special functions can be prepared according to specific engineering requirements, such as slow release type, early strength type, anti-shrinkage type and low bleed type. , low viscosity type, etc. The main steric hindrance group of the polycarboxylate superplasticizer is the longer polyoxyethylene side chain. The nature of the water-soluble nonionic polyoxyethylene soft segment allows its conformation in aqueous solution to vary. The conformational state of the side chain has a great influence on the water reducing agent.

  • What is a concrete admixture

    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, it is generally not more than 5%. Although it contains a small amount, it has played an active role in improving the performance of concrete and has become an indispensable part of the current development of concrete. The additives used in concrete mainly refer to different types of water reducing agents. The extensive promotion of concrete admixtures has led to significant improvements in the strength of the concrete, its brittleness and its own weight, and has improved the applicability of concrete construction. For example, adding antifreeze to concrete can make concrete construction work in the cold winter. The use of superplasticizers enables the renewal of concrete placement and flow regimes.

  • concrete admixtures

    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.

  • Selection of Concrete Admixtures

    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.
