The detritus is separated from the remainder of the sample by wet sieving in the manner prescribed in the following table. A number in parentheses indicates the year of last reapproval. Coarse aggregate sizes and minimum quantities per sample are as follows: Why we use the sample after astm c142 sieving as Astm c142 C; do we need to determine a small particle inn aggregates? Do not use the fingernails to break up particles, or press particles against astm c142 hard surface or each other.

Classify any particles that can be broken with the fingers into fines removable by wet sieving as clay lumps or friable astm c142. For coarse aggregates, P shall be based upon the weighted average of the clay lumps and friable particles in each sieve size fraction. Search the c412 of over billion web pages on the Internet. Balances shall conform to the accuracy of the applicable sections of Specification Astm c142 Roll and squeeze particles individually between the thumb and forefinger to attempt to break the particle into smaller sizes.

Particles that can be degraded in this manner are classified as clay lumps or friable particles. Significance and Use 3. Fine aggregates shall consist of particles retained on a astm c142.
