Tips for Curing Concrete in Cold WeatherConcrete Slump Test Definition Types Procedure
Aug 23 32 The process of curing concrete becomes more challenging in cold weather since to properly set and reach maximum strength fresh concrete must be protected from freezing for at least the first 24 hours or until it reaches a minimum strength of 500 pounds per square inch psi Concrete that freezes at an early age can lose much of its overall strengthConcrete Slump Test is a standard and quick test to determine the proportions of various ingredients for preparing concrete of desired consistency and workability Workability The ease with which one can work with concrete is called workability this can be measured using a simple test called the slump test
