WHAT ARE THE PROPERTIES OF AGGREGATES FOR CONCRETE Compressive strength Wikipedia

Oct 01 32 The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads Also read Crushing Value Test of Aggregat 13 Impact Value The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impactCompressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size as opposed to tensile strength which withstands loads tending to elongateIn other words compressive strength resists compression being pushed together whereas tensile strength resists tension being pulled apart In the study of strength of materials

Crushing Strength The Wood DatabaseThe Effect of Aggregate Properties on Concrete

In comparison White Oak is a well known wood used in cabinetry and furniture and has a crushing strength of 7 440 lb f /in 2 513 MPa and Redwood is commonly used for decking and has a crushing strength of 5 690 lb f /in 2 392 MPa The compressive aggregate strength is an important factor in the selection of aggregate When determining the strength of normal concrete most concrete aggregates are several times stronger than the other components in concrete and therefore not a factor in the strength of normal strength concrete

Maximum crushing strength is the maximum stress sustained by a board when pressure is applied parallel to the grain Impact bending involves dropping a hammer of a given weight upon a board from successively greater heights until complete rupture occurs The height of the drop that causes failure provides a comparative measure of how well the Definition Strength of hardened concrete measured by the compression test The compression strength of concrete is a measure of the concrete s ability to resist loads which tend to compress it The compressive strength of concrete is measured by crushing cylindrical concrete specimens in compression testing machine
