STANDARD PROCEDURES FOR TEMPERATURE CONTROLLED CONCRETING

STANDARD PROCEDURES FOR TEMPERATURE CONTROLLED CONCRETING 1.0      PURPOSE: This procedure covers the required methods for mass concreting in controlled temperature to prevent cracking caused by excessive tensile strains that result from temperature differential within the concrete mass. Cracking can be controlled by methods that limit the peak temperature to a safe level. These method statements have been prepared to provide a general guide, special considerations to be given in relation to the heat of hydration for concrete pours . 2.0       SCOPE: These method statements includes e.g. pre-cooling procedure before & during concrete mix, supply & delivery of concrete, inspection of concrete at the workface and post cooling by a proper cooling upon a completion of concrete placement. 3.0      REFERENCE STANDARD: 2.1       IS: 456, IS: 10262,...
