The major advances and innovations in concrete technology have for the most part been a function of the rapidly expanding use of of chemical  admixtures. For example, two specific type of admixtures, superplasticizers and and air entraining agents, have had a significant impact on extending the durability and engineering properties of cementititous mixtures. As with all technologies, successful use will only result when specific admixtures are added for the correct application and with the appropriate dosage range. With 34 years experience as a scientist in chemical admixture industry, Dr. Jeknavorian can provide a wide range of services to enable consistently successful application of chemical admixture technologies for the concrete construction industry.
