Determination of the properties of Portland cement in presence of silica fume and superplasticizer C-3
A.A. Spiridonova, A.V. Voronova, V.M. Sultanova
In this article, the problems of the influence of chemical and mineral admixtures on the properties of cement binder are discussed. The main goal is the analysis of the studies of the properties of Portland cement with the introduction of microsilica and superplasticizer C-3. Tests were carried out to determine the fluidity of the microsilica slurry and its stratification, the water demand of silica fume and cement, and the strength of the composite binder for compression at day 7. When obtaining a slurry of microsilica with a content of NTFC and superplasticizer, it was determined that the acid leads to stratification of the suspension and the superplasticizer to homogeneous system of its solid phase. During the tests to determine water demand and compressive strength of cement, it was found that its characteristics improved as a result of the interaction of additives, namely, to increase the strength, reduce water consumption, increase strength, etc.
