EFFECT OF COLD WEATHER ON CONCRETE STRENGTH AND

The effect of cold weather on concrete strength and durability is an issue that surfaced recently on one of our projects where the night time ambient temperature fell to -4ºC, i.e. below the specified lower threshold of 5ºC. In this instance the surface temperature of the LCS dropped to 1ºC, but the minimum

How to Determine the Aggregate Crushing Strength Value

Procedure for crushing strength of aggregate Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.
