METHOD TO PREPARE LIGHTER MASONRY MORTAR AND COMPOSITION FOR LIGHTER MASONRY MORTAR Russian patent published in 2014 - IPC C04B28/04 C04B111/20 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular, to compositions and methods to produce lighter masonry mortars designed to arrange enclosures from effective small elements. The method includes mixing of portland cement with water and superplasticiser S-3 in a mortar mixer, subsequent introduction of hollow glass microspheres into the produced mix, mixing of all components of the mortar and subsequent extrusion of the produced composition at the following ratio of components, wt %: portland cement - 37.5…67.2, hollow glass microspheres - 6.7…18.7, modifying additive - 0.28…0.50, water - 25.5…43.5. A raw composition for production of a lighter masonry mortar is produced by the above method.

EFFECT: reduced average density and increased strength of a lighter masonry mortar.
