METHOD OF PREPARING OF CONSTRUCTION MORTARS AND CONCRETES BASED ON THEM Russian patent published in 2009 - IPC C04B11/30 

FIELD: chemistry.

SUBSTANCE: invention relates to construction materials production and deals with method of preparing of construction mortars and based on them concretes. Cement, live lime, quartz sand, crushed diatomite raw material and water are mixed. Diatomite raw material is used in form of 1-3 mm fraction not less than wt % 50, and not more than 5 mm - the remaining part. Mixing is performed by introduction of water suspension of said raw material into preliminarily prepared mixture of cement, lime, quartz sand and coarse filling agent, with the following component ratio, wt %: Cement 20-30; Live lime 4-6; Coarse filling agent 0-20; Quartz sand - the remaining part. Diatomite raw material - 5-30 of cement weight; water - until cone subsidence is 1-9 cm.

EFFECT: obtaining construction mixtures and based on them concretes using existing technological lines without decrease of final product quality.
