Gypsum Wallboard Chemical Additives. Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needlelike gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength.
Gypsum As An Additive To Cement. Such as glucose and citric acid delay gypsum hydration as they can be hydrated easier than gypsum 2 3 citric acid acts as one of the most effective retarders among the chemical additives nco 3 produces gas to obstruct the hydration 4 5 natural fibers ar,Gypsum As An Additive To Cement.
Cement amp; Concrete Additives. Cement amp; Concrete Additives presents historical demand data (2005, 2010, 2015) plus forecasts (2020, 2025) by type of additive (fiber, chemical, mineral) and market (nonresidential building, residential building, highway and street, other) The study also considers market environment factors, assesses the industry structure and evaluates company market share...
Forton#174; VF774 is the worldwide standard concrete additive for making lightweight GFRC panels. It is recognized by the PCI as the only polymer supported with a 20 year durability study. Alpha gypsum additives make gypsum far stronger and more weather resistant. Forton#174; and Matrix products are a lower cost alternative to resins.
Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.
Concrete amp; Gypsum Additives Forton and duoMatrix systems will greatly enhance the physical and performance properties of concrete and alpha gypsum. Today, Glass fiber reinforced concrete (GFRC) is one of the most popular and innovative building materials used throughout the United States, Europe, Middle East and Asia.
Cement additive and cement composition Cement Lime Gypsum (1) A cement additive that comprises a limesulfur mixture having a pH of 10 or more and that has an excellent ability to maintain the fluidity of cement concrete and reduce autogeneous shrinkage.

What is the purpose of adding gypsum in cement?
gypsum cement additive, Cement additives based on PCE Cement Lime Gypsum. 01/02/2011 Summary: The rising demands on modern cements require continuous development of cement ether (PCE), although used around the globe as concrete admixtures, remain largely unknown for the use in cement.
Summary: The rising demands on modern cements require continuous development of cement ether (PCE), although used around the globe as concrete admixtures, remain largely unknown for the use in cement. This article examines the effects of PCE cement additives on the basis of a series of tests performed both in laboratory and on industrial scale.
