Cement Standards and Concrete Standards 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.
The finite element method is commonly used to design the reinforcement in concrete slabs. In order to simplify the analysis and to be able to use the superposition principle for evaluating the effect of load combinations, linear analysis is generally adopted even though concrete slabs normally have a pronounced non-linear response.

Asphalt concrete mixtures can be classified in many different ways. Perhaps the most general type of classification is by whether or not the mix must be heated prior to transport, placement, and compaction. Asphalt mix concrete must be thoroughly heated during mixing, transport, placement, and compaction.
