So the cracks in the concrete may form at two different times. They can appear during the setting or curing time, or they can appear due to the structural failure of concrete itself. To understand both of them, it is important to understand what c...
Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types: Calcium silicate hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to "C-S-H," the dashes indicating ...

ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
Worldwide, more sand and gravel is mined annually than any other industrial raw material. Preliminary estimates of sand and gravel production in Arkansas for 2007 by the U.S. Geological Survey are nearly 9.1 million metric tons valued at $66,300,000. Nearly fifty percent was used for concrete aggregate and concrete products.
