MECHANICAL ACTIVATION OF RICE HUSK AS A FINE ACTIVE MINERAL ADDITIVE IN BUILDING SOLUTIONS

In many rice-producing countries of the world, including Uzbekistan, they are aimed at using rice husk ash as a finely dispersed active mineral additive in building mortars. The composition of the ash was studied by the method of laser granulometry and the values of the indicators characterizing the dispersion of its particles before and after mechanical activation were determined. A comparison was also made of the pozzolanic activity of rice husk ash, fly ash and microsilica by the method of absorbing lime from a solution with an active mineral additive.
