  • Patent number: 9676667
    Abstract: The present invention concerns a process for oxidizing lignin at alkaline conditions. This oxidized lignin can be used as a dispersant in various end-products, for example as a renewable plasticizer in cement-containing products, such as concrete, where the ability of the oxidized lignin to endure alkaline conditions is an advantage. Further, the invention concerns a concrete mixture containing aggregate, cement, water and a plasticizer formed of oxidized lignin, and a process for producing such a concrete mixture. The oxidized lignin can be manufactured using a process, where the lignin starting material is reacted with an oxidizing agent in solution in alkaline conditions.

  • Patent number: 9630880
    Abstract: A concrete product is produced by providing red dune sand having a particle size of 45 microns or less and mixing the red dune sand with hydraulic cement in a ratio of about 30% of the cement being replaced by the red dune sand. The cement and red dune sand are then mixed with fine and course aggregate, water and a superplasticizer and cast after pouring into a mold cavity. Then within 24 hours of casting, the cast article is steam cured for 12 hours under atmospheric pressure, demolded and placed in an auto clave at 100% humidity. The temperature in the auto clave is raised to 180° C. within one to two hours and maintained at that temperature for 4 to 5 hours. The temperature also increases the pressure to about 10 bars. The pressure is released to reach atmospheric pressure within 20-30 minutes and the temperature reduced gradually, so that the article can be removed.
