The possible apparent particle density values for normal United Kingdom aggregates range between 2.4 and 3.0 Mg/m 3 but the majority are in the narrow 2.5â2.7 band (Table 15.8).Aggregate particle density usually is not directly related to concrete performance in the materials sense, but might be relevant from a structural standpoint (e.g. The density of light weight concrete is about 1900 kg/m 3 and that of normal concrete about 2400 kg/m 3. 1. The relative density of aggregate The variability in density can be used to produce concrete of widely different unit weights, see Table (1). Set includes pycnometer with conical mold and tamper. The base is to a depth of 4 inches. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3). gravity structures). The percentage of all types of harmful matter in fine aggregate should not surpass 5%. I will use a custom material of unknown density which weighs 200 lb per four cubic feet and costs $60 per US short ton. Related Topics . Figure 3.4 Schematic of Dry Lightweight Aggregate 3.5 Aggregate Bulk Density Aggregate bulk density is defined as the ratio of the mass of a given quantity of material and the total volume occupied by it.
