Influence of Local Sand on the Physicomechanical Comportment and Durability of High Performance Concrete

Table 3

Physical characteristics of the mixed fine aggregates (crushed and dune sand).

Sands	App (g/cm^3)	Ab (g/cm^3)		(%)	(%)	(%)
CS	1.95	2.70	3.29	72.23	27.77	38.45
1/3 SD + 2/3 CS	2.02	2.64	2.63	76.5	23.48	30.68
2/3 SD + 1/3 CS	2	2.63	2.94	75.05	23.95	31.49
SD	1.9	2.65	1.71	71.7	28.3	39.47

App: apparent density, Ab: absolute density (g /cm³), : fineness modulus, : compactness (%), : porosity (%), and : void ratio (%).
