  • Additive Manufacturing in Construction

    Additive manufacturing in construction is closely linked to the type of material that is being printed. The method used to create the building part is dependent on the material used, with concrete, metals, or polymers (plastics) being the most common.

  • Chemical Admixtures

    Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or compaction. The effect of superplasticizers lasts only 30 to 60 minutes, depending on the brand and dosage rate, and is followed by a rapid loss in workability. As a result of the slump loss, superplasticizers are usually added to concrete at the jobsite.
