METHOD OF CONCRETE STRENGTH GROWTH MONITORING DURING HEAT TREATMENT

摘要

FIELD: construction.SUBSTANCE: method involves measurement of hardening concrete temperature at given time moments and calculation of concrete strength over three days for hardening in standard conditions by the formula:where R, % is concrete strength gained in time ?, days, Kis temperature factor depending on concrete hardening temperature and three-day strength.EFFECT: reduced labour consumption of monitoring.1 tbl, 2 dwg
