Introduction
In order to determine the aggregate distribution of cold ramming paste, no adhesive obtained aggregate is necessary, the best method is to use common solvents mention
Take adhesive. Coal tar and asphalt, the binder is the most common and effective quinoline. Most of the tar is not completely dissolved in quinoline,
A small portion of insoluble materials, the insoluble matter mainly contains particles smaller than 50μm solid char particles. These insolubles are cold ramming paste aggregate
The actual component is measured by this method. Effective adhesive defined as quinoline dissolved part.
In the current method is the most effective quinoline solvent. Its disadvantage is that expensive and high boiling point, due to the high boiling point, according to the drying place
Processing procedure, quinoline completely removed from the residue extracted is very difficult. However, when the need to maximize the separation of the binder from the aggregate,
Quinoline is the best choice, given the use of the standard method of quinoline.
NOTE. this applies in dichloromethane technical standards, simply remaining on the filter to remove quinoline prior to drying.

3 PRINCIPLE OF THE METHOD
In a flask equipped with a reflux pipe with quinoline dissolved in cold ramming paste sample binder, dissolution was complete, the mixture was poured onto a fine aperture
The sieve, sieve material is a major component of aggregate, rinse the residual aggregate with quinoline, and then dried and weighed. Sieve with filter paper
Next thing, in very fine aggregate particles remaining on the filter paper, is the sum of the aggregate content on the screen and residues on the filter paper, and quinoline solubles
Content obtained by subtraction.
Test sieve residue after the particle size distribution by sieve test set is determined.
