Comparative Properties of Luminous Binders on the Basis of Soda Ash, Introduced in Concrete in the Dry and as Water Solution
Abstract: The possibility of introducing soda ash into the slag-alkali concrete in a dry state in the composition of a bicomponent binder during grinding along with a blast-furnace slag has been found out. For the production of concrete with strength comparable to the strength of concrete prepared on pre-dissolved soda, the consumption of dry soda should be increased by 50…70 %. The introduction of soda into the concrete mix and its mixing for 4–6 minutes before the introduction of coarse aggregate reduces the over-consumption of soda to zero with the use of cold water and up to 2–4 minutes when using water heated to 60 °C.
Keywords: slag-alkaline concrete, soda ash is dry and in the form of a solution, hardening conditions, strength.
