Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needle-like 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. After drying, the frictional forces of these crystals increase the strength of the core.
Cement Standards and Concrete Standards ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

Forton® VF-774 is the world-wide 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® and Matrix products are a lower cost alternative to resins.
Concrete Additives. In the construction industry our additives are used to reduce the cost of concrete construction, to optimize concrete properties and to ensure reliable and consistent quality of concrete. With our long-standing expertise in surfactant technology, we developed tailor-made solutions for the admixture market.
Additives are chemicals and materials blended into base cement slurries to alter the performance of the cement. Due to the inherent nature of base cements (Neat, Portland and Pozzolanic) and because of the demands placed on the cement sheath throughout the life of the well, the performance properties of the cementing slurry are modified to address the specific and unique conditions of each well.
