Infrared spectr of SP-2VU superplastifying agent and a cement mortar with additive

To improve the concrete properties, various technological methods are used, the most accessible ones being the introduction of chemical additives into the concrete mixture, which can significantly reduce the costs level per unit of production; these additives improve concrete quality and effectiveness and reinforced concrete structures as well as increase their service life and buildings and structures in whole. This paper presents the results of studying the effect of introducing a superplasticizer with stabilizing effect of Polyplast SP - 2VU LLC Polyplast Novomoskovsk into concrete by analyzing the IR spectra of the additive in pure form and as part of hardened cement mortar (0.1-0.9%). Portland cement CEM I 42.5 B of Mordovcement OJSC was used as a binder; the aggregates were enriched with quartz sand from the Khromtsovsky deposit with a size of 2.4 and granite crushed stone of the Orsk deposit of 5-20 mm with water absorption of 0.2% . In the course of the work, the chemical composition of the additive SP2-VU itself and the hardened modified concrete composition were analyzed...
