  • Alumina-modified colloidal silica particles, cementitious products containing same, and methods of use thereof
    Patent number: 11542168
    Abstract: Alumina-modified colloidal silica nanoparticles mitigate Alkali Silica Reaction (ASR) in cementitious compositions. Additives containing the nanoparticles are used in methods of reducing ASR in concrete and to form cementitious compositions. Cementitious products, such as concrete, made by these methods are described herein.
    Type: Grant

    Inventors: Jonathan S. Belkowitz, WhitneyLe B. Belkowitz
  • Tension testing apparatus
    Patent number: 11513045
    Abstract: A tension testing apparatus and system is disclosed in which the tension testing apparatus includes a first box including a first outer plate and a first inner plate, a second box including a second outer plate and a second inner plate, and a test sample holding system coupled to the first inner plate and the second inner plate. The first outer plate and the first inner plate may be coupled together by at least two rods. The second outer plate and the second inner plate may be coupled together by at least two other rods. The test sample holding system may be configured to hold a test sample. The at least two rods of the first box may be configured to pass through the second inner plate. The at least two rods of the second box may be configured to pass through the first inner plate.
