Producing meaningful concrete and aggregate test results rely heavily on following strict procedures in test methods and practices published by ASTM, AASHTO, and other organizations Requirements for tests on aggregates, concrete compressive strength tests, and other methods are written in clear, concise language following form, content, and style guidelines, but often lack basic explanatory
Testing tip: Test cylinders that are poorly made, stored, or neglected will cause headaches and may result in the need for costly hardened concrete testing, all to provide the owner information proving that the actual inplace concrete is of sufficient strength and durability While this procedure is simple, do not take it lightly There are a number of reasons why cylinder strengths might be

· The aggregate sample: The material for the standard test consists of aggregates sized 100 mm to 125 mm The aggregates must be in a surface dry condition before testing The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary
In most concrete, aggregates are more or less chemically inert However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years This alkaliaggregate reaction has two forms: alkalisilica reaction (ASR) and alkalicarbonate reaction (ACR) Alkalisilica reaction (ASR) is of more concern because aggregates containing reactive
