Composite panel of low shrinkable foam mortar
专利汇可以提供Composite panel of low shrinkable foam mortar专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent the warping and twisting of a panel and the cracking of thin or thick plates by lining the thin or thick plate to arbitrary thickness with a foam mortar layer using the cement low in shrinkage and also good in foaming stability.
CONSTITUTION: Cement consists of calcium sulfoaluminate clinker, Portland cement, gypsum and blast furnace water-granulated slag and its hydration produces the hydrate of calcium silicate and calcium hydroxide from the Port land cement and also ettringite from calcium sulfoaluminate compounds, gypsum and calcium hydroxide. Therefore, due to the production of an expandable hydrate of the ettringite in a large amount, the hardened cement body lower in shrinkage results with its shrinkage compensated. Due to the absence of calcium hydroxide, moreover, air bubbles will not be defoamed by Ca
2+ ions and fine closed bubbles are obtained with an improved foaming stability. An exterior wall panel for housing application is the ceramic plate 11 lines with a foam mortar layer 12.
