FIELD: construction.
SUBSTANCE: invention relates to production of double-layer kauton-concrete girders. Method comprises making concrete of upper layer with frame. After 28 days, after development of concrete strength, kauton bottom layer is made. Contact between layers is strengthened with lugs and cuts. After laying layer of kauton, double-layer element is placed in dry warm-up chamber, where curing process occurs at a temperature of 120±5 °C.
EFFECT: high reliability, durability and strength of beams.
