What is the density of coarse aggregate?
The coarse aggregate density used for construction is generally between 1450 – 2082 kg/m3 The density of coarse aggregate varies depending on the source, nature, and condition like wet or dry.
Why is apparent specific gravity greater than bulk specific gravity?
The bulk or volume specific gravity is based upon the volume as a whole–i.e., the solid material with all included pores. The apparent specific gravity is based upon the volume of the solid material plus the volume of the sealed pores.
What is the difference between the bulk dry specific gravity of aggregates and the bulk SSD specific gravity of aggregates?
Relationship with Other Specific Gravities Both use the aggregate’s oven dry weight. The difference between Gsb and bulk (SSD) specific gravity is the weight of aggregate used in the calculations. The difference between these weights is the weight of absorbed water in the aggregate’s permeable voids.
Why bulk density of aggregate is important?
The bulk density measures the volume that the graded aggregate will occupy in concrete, including the solid aggregate particles and the voids between them. Additionally, the bulk density is required for the volume method of mixture proportioning.
What is the difference between bulk density and apparent density?
Apparent density is the bulk density of the powder. It provides the mass per unit volume of loose packed powders. A change in apparent density can also indicate a change in the surface roughness of the powder; for example, atomization satellites may reduce apparent density.
Why bulk density of aggregates is important?
For the purpose of mixture proportioning, it is important to know the space occupied by the aggregate particles, including the pores within the particles. The bulk density measures the volume that the graded aggregate will occupy in concrete, including the solid aggregate particles and the voids between them.
What is the difference between plain coarse aggregate and GSB?
Given the constant bulk volume, Plain coarse aggregate is having pore spaces and the GSB is filled with small particles, which will add mass within spaces and conversely the density too. Thanks. [ 2] What is the density of soil?
What is meant by coarse aggregates with higher bulk density?
If a statement is like: A coarse aggregates with higher bulk density, then it means few of the voids can be filled by using fine aggregates and cement. For testing, British Standard (BS 812) has specified the degree of compaction. These are;
What is the difference between GSB and bulk (SSD) specific gravity?
The difference between Gsb and bulk (SSD) specific gravity is the weight of aggregate used in the calculations. The difference between these weights is the weight of absorbed water in the aggregate’s permeable voids. Both use the same aggregate volume.
What is a coarse aggregate specific gravity test?
Overview. The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the fine aggregate specific gravity test.
