METHOD FOR CONTROL OF CONCRETE strength development by 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 τ, days, K_t is temperature factor depending on concrete hardening temperature and three-day strength.;EFFECT: reduced labour consumption of monitoring.;1 tbl, 2 dwg
