PROCESS OF TREATMENT OF MONOLITHIC STRUCTURES WITH CONCRETE Russian patent published in 2003 - IPC

Abstract RU 2208093 C2

FIELD: construction industry, encasement of various structures in monolithic concrete with stage-by-stage erection of elements. SUBSTANCE: process includes cutting of structure into blocks, heating of foundation before laying concrete mixture, laying of concrete mixture into forms, its subsequent vibration and curing of concrete in forms till it acquires required strength. Novelty of process lies in heating of foundation to temperature of 10-20 C and in casting of concrete mixture with temperature of 20-25 C into forms to height 0.4-0.7 m and in laying of concrete mixture with temperature of 6-10 C to the rest of structure height. Permitted length of block encased in concrete is found by given dependence. EFFECT: diminished probability of crack formation and increased construction rate. 2 dwg
