APPLICATION OF DUMP ASH FROM KYZYLORDA COMBINED HEAT AND POWER PLANT IN HEAVY CONCRETE

In the article the task was set to study the use of mechanochemical activation of ashes from hydraulic removal and their further application as mineral additives in concrete mixes. Concrete based on blended cement has a higher strength both at standard and steam curing. It is most noticeable at early stages of standard curing and at short-term steam curing. The introduction of complex chemical additive into the binding agent raises the strength of concrete and reduces the consumption rate of Portland cement by half. For this reason the use of ashes from Kyzylorda combined heat and power plant allows to solve the task of consumption rate reduction of Portland cement effectively and enhance quality of concrete.
