FIELD: construction.
SUBSTANCE: invention relates to the field of construction materials and specifically to the production of light concrete and can be used in building structures of civil, public and industrial buildings. Method for preparing a wood filler for wood concrete comprises soaking the wood and maintaining aggregate in 20 % aqueous silica sol having a particle size of 20–40 nm, the exposure time is 20 minutes at temperature of 20 ± 2 °C.
EFFECT: technical result is simplification of technology of preparation of wood filler, high strength of wood concrete.
