produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an aggregate suitable or unsuitable for use in concrete. The

Civil Engineering Design (1) 6 Dr. C. Caprani From the figure: • For lh≤15 the crushing capacity is much lower than the buckling capacity and so the column crushes. • For lh>32 the buckling capacity is less than the crushing capacity and so the column buckles. • For lh values in between, the failure mode is not clear and depends on

Table 4 shows density of concrete cubes ranging from 2441kg/m³ to 2588kg/m³.These values fall within the density values for normal weight concrete as stated by Neville (2000). It can be seen that the densities of the specimen increase with the days of curing, which suggest that there is no deterioration of the said concrete.
