Современные методы химического анализа особенно актуальны для определения химического состава материалов, используемых в строительстве. На настоящий момент, в области химического анализа наиболее сбалансированным по соотношению цена - качество является метод атомно-эмиссионной спектрометрии с индуктивно связанной плазмой (ИСП-АЭС). Определение химического состава таких материалов, как цемент, песок и щебень, выполняется согласно нормативным документам по методам, которые являются методами химии растворов. Сопоставление результатов определения химического состава данных материалов по методам химии растворов и по методу ИСП-АЭС показало, что абсолютное отклонение результатов для оксидов каждого определяемого элемента не превышает величину 0,05%. Данный факт подтверждает высокую эффективность метода ИСП-АЭС применительно для определения химического состава компонентов бетона. В статье приведен метод подготовки проб цемента, песка и щебня для проведения ИСП-АЭС анализа, представлены аналитические линии для каждого определяемого элемента и рассмотрен процесс обработки результатов анализа.

The modern techniques of chemical analysis are especially significant for determination of the chemical composition of building materials. At present moment, in a field of chemical analysis, the most balanced technique in terms of price and quality is the inductively coupled plasma atomic emission spectrometry (ICP-AES). Determination of chemical composition of such materials as cement, sand and crushed rock are carrying out according to codes GOST 5382, GOST 8735 and GOST 82169.1, using techniques that in fact are techniques of the classical chemistry, which are so called “chemistry of solutions”. Comparison between the results of determination of the chemical composition of such materials that were obtained by techniques of the chemistry of solutions and by ICP-AES technique, showed that absolute deviation of results for the each determined element’s oxide were not higher than the value of 0.05%. This fact confirms that ICP-AES technique is highly effective for determination of the chemical composition of materials using for making concrete. The preparation technique for samples of cement, sand and crushed rock, analytical lines for the each determine element and processing of the results for ICP-AES technique are presented in this article.
