PDF Additive Formwork for Concrete Shell Constructions
Additive Manufacturing is rapidly developing in the area of concrete constructions. However, to date, several challenges still exist in terms of material and structural performance, which require
Construction Chemicals for Concrete
2018-2-27 · The production of concrete requires intensive mixing with water. The shear forces introduced during mixing, in combination with surface-active components in the concrete formulation, result in the distribution and stabilization of uncontrolled air in fresh concrete. Defoamers are used for the prevention and removal of this undesired air.
Additive for concrete AB Alfong
An additive for concrete consisting essentially of a substantially saturated aqueous solution of sodium sulfate having suspended therein 10 to 70% by weight of the total weight of the additive of fine silica particles and 0.002 to 2% by weight of the total weight of the additive of a wetting agent consisting of a lyotropic liquid crystal.
AQURON 300 Admixture for Concrete
AQURON 300 additive reduces shrinkage and slabcurl to a minimum, while improving density, anti-dusting, and surface hardness. Cement particles are more effectively “saturated” by the AQURON 300 mix water and this subsequently increases the quantity of hydration products per cement particle, optimising achieved strengths, and contributing to a significant drying shrinkage compensation
ADDITIVE FOR CONCRETE AND MORTAR MO OCH
An additive for concrete and mortar containing an inorganic binding agent, consistently essentially of (1) an amount within the range from about 0.01 to about 2 parts by weight of sulfite waste liquor on a dry basis and (2) an amount within the range from about 0.001 to about 1 part by weight of polyalkylene compound selected from the group

Additive Models Carnegie Mellon University
2014-5-2 · Additive estimates tend to balance the strengths of the fully nonparametric and parametric estimates. I.e., additive estimates tend have a lower variance than fully nonparametric ones, and can have a lower bias than parametric ones The main downside: by restricting the estimate to be additive, we miss potential interactions between variables.
