CHEMICAL AND PHYSICOCHEMICAL CONTROL OF CEMENT PRODUCTION

 

The Chemical-Analytical (Testing) Laboratory of JSC NIICEMENT, using modern methods of chemical analysis, is engaged in:

- development, production, certification and implementation of industrial, state, and international standard samples of the composition of cement production materials to ensure the uniformity and accuracy of measurements during the chemical and physicochemical control of the cement production process (see Table 1):

- certification of newly produced and re-evaluation of existing (to extend the validity period) works standard samples of the composition of cement production materials for a particular enterprise applied to calibrate X-ray spectroscopic equipment for express-testing of the chemical composition of materials;

- determination of the chemical composition of mining development raw materials to further assess their suitability for the production of binding materials; all types of cement, including for the purpose of certification; lime; dry mixes and other construction products; by-products of metal, chemical and energy industries (blast-furnace and electrothermophosphoric slag, belite sludge, ash and ash slag from TPPs, slag and dust from ferroalloy industry, etc.).

- training of analysts of industrial laboratories using modern methods of determining the chemical composition of cement production materials and reference methods of identifying mineral additives in cement according to GOST 5382-91 “Cements and materials of cement production. Chemical analysis methods.” and GOST Р 51795–2001 “Cements. Methods for determination of content of mineral additives.”

This offer is carried out upon customers’ request by the Chemical-Analytical (Testing) Lab. of JSC NIICEMENT that has a state accreditation - Accreditation Certificate of Testing Laboratory (Center) No. РОСС RU.0001.22CM40 (No. 000473).
