Study of the influence of magnetized ferromagnetic additives on the processes of cement hydration

One of the essential tasks for a sustainable future is to reduce harmful emissions into atmosphere significantly. Cement production world’s largest industrial carbon pollutant, accounting 8 % global emissions. More than 2.2 gigatons dioxide are emitted every year. Therefore, reducing energy intensity products and number in cement becoming critical. strategy most energy-consuming component – clinker. In this case, various activation methods used maintaining same level activity. these impact on hardening binder with magnetic fields. The paper presented study hydration processes blast-furnace activated by magnetized ferromagnetic additive. work established that introduction pre-magnetized dust composition has an activating effect hydration. It shows occurs both initial long periods hardening. nature mutual influence components system alite-lime-slag modified was revealed. investigation determined additive, intensifying process slag hardening, increases proportion hydrated 1.5-2 times. revealed formation ettringite framework binder’s gel completed within one day. shown subsequent periods, aluminates mainly due tricalcium aluminate hexahydrate (C 3 AH 6 ), which excludes destructive late been under action degree crystallization hydro silicates increases.
