An admixture dispensing method that dispenses a dispersant admixture raw material and other admixture raw materials to cementitious compositions based on performance characteristics such as compressive and flexural strength, slump, setting time, air content, finishability, and material or process variables such as temperature, cement type used, additives such as pozzolan, and water cement ratio desired. The method may use computer software algorithms or lookup tables to determine an adjustable ratio of admixture raw materials that when added to the cementitious composition produces the desired performance characteristics. The method may calculate non-linear dosage rates between polycarboxylate dispersant admixture raw materials used for water reduction and strength generation and defoamer admixture raw materials to determine the correct amount of each to generate the desired air content in a cementitious composition.
A method for supplying adjustable ratios of admixture raw materials to a cementitious composition to generate desired performance characteristics comprising:
