Making and Curing Concrete Cylinders
The cylinders are immediately placed where they are going to stay until the concrete sets up. During this phase, what C 31 calls initial curing, the cylinders can stay in this location for up to 48 hours, but must be kept at a temperature between 60° and 80° F and in a moist environment. C 31 gives us several ideas on ways to achieve this ...
Test on Coarse Aggregates
This test is conducted to determine the crushing strength of aggregate.

The specifications for this test are given in IS : 2386 Part IV 1963 mechanical properties.
WHAT are Concrete Test Cylinders?
Move cylinder molds with fresh concrete very care-fully by supporting the bottom. Place the cylinders on a flat surface and in a controlled environment.

How Producers Can Correct Improper Test-Cylinder Curing
Producers' concerns are justified. Although several studies show cylinder-strength losses of about 15% due to improper curing, proper jobsite curing is too often ignored, especially during the critical first 24 hours. A 600-psi strength loss for 4000-psi concrete can easily cause out-of-tolerance cylinder test results, making producers the ...
