Cement samples are prepared by method which is displayed below. N. Lushnikova, L. Dvorkin, in Sustainability of Construction Materials (Second Edition), 2016 25.2.3.1 Wall blocks. Ordinary and water-resistant gypsum binders, synthetic gypsum and normal-weight and lightweight concrete can be applied for manufacturing. Blocks can be solid or hollow. A common size is 390 Ă— 190 Ă— 188 mm. Compressive strength varies from 2.5 to 10 MPa. The chemical analysis of cement components is widely used in the c ement industry for production optimization and stable high-quality assurance of the final product. High requirements for cement quality are formed by its usage in the fabrication of concrete the most consumed material in the building industry. 2022-5-13 Gypsum Fact Sheet.docx Page 1 of 4 FERTFACTS GYPSUM INTRODUCTION Gypsum is the common name of hydrated calcium sulphate, which has the chemical formula CaSO 4.2H 2O.
