    CAC as an Accelerator for OPC (or other cements)
    Oral Presentation

    In an increasingly competitive market, the precast industry is constantly looking for ways to ensure a quick turnaround and rapid delivery with an acceptable cost and without harming the quality of the final concrete element. One of the most common levers allowing to boost production cycles is to adopt advanced curing techniques like steam curing or heat curing. These options are not...

    CAC as an Accelerator for OPC (or other cements)
    Oral Presentation

    TThis study investigates the hydration behavior of quaternary binder systems comprising calcium aluminate cement (CAC), ordinary Portland cement (OPC), calcium sulfate (C$), and various supplementary cementitious materials (SCMs) under different curing temperatures. The binder composition was fixed at CAC:OPC:C$:SCM = 53:13:24:10 by mass. SCMs, including ground granulated blast furnace slag...

    CAC as an Accelerator for OPC (or other cements)
    Oral Presentation

    Cementitious foam technology, despite being known for decades, has faced limitations in widespread use due to technical challenges. The main issues include slow setting and hardening, low mechanical performance at early age, particularly in low-density foams, as well as shrinkage problems, and limited application range.
    To address these challenges, an ettringitic accelerator based on...

    CAC as an Accelerator for OPC (or other cements)
    Oral Presentation

    In recent years, the increasing requirements for thermal insulation in building construction and society's growing environmental awareness have led to the increased development of highly thermally insulating, recyclable cement-based mineral foams with low thermal conductivities (λ ≤ 0,035 W/(m·K)) and low dry densities (ρ ≤ 70 kg/m³). Their production and application are associated with...

    Carbon Footprint
    Poster Presentation

    The incorporation of Calcium Aluminate Cements (CACs) into modern building chemistry products enable rapid set, fast hardening and quick drying. Apart from application demands, the CO2 footprint of the products needs to be lowered as well to minimize climate impact. One avenue to reduce CO2 is to decrease the cement content in the product formulation. The patented CAC Flex offers a solution...

    CAC as an Accelerator for OPC (or other cements)
    Oral Presentation

    This study investigates the drying behavior and degree of hydration (DOH) of ternary cementitious systems composed of Portland cement (PC), calcium aluminate cement (CAC), and calcium sulfate (CS) sources using neutron radiography. CAC-based ternary binders can be preferred in interior flooring applications due to their self-leveling characteristics, rapid early strength development, and fast...

    CAC as an Accelerator for OPC (or other cements)
    Poster Presentation

    Lignin, the second most abundant biopolymer in plant structures after cellulose, is produced at a rate of approximately 50 million tons per year during industrial paper manufacturing. Lignosulfonates, derived from the sulfonation of lignin, are water-soluble anionic polyelectrolyte polymers that find widespread applications in various industries. In concrete technology, lignosulfonates are...
