Rapid evaluation method suitable for performance of pebble mother rock of machine-made aggregate

Abstract

The invention relates to a rapid evaluation method suitable for performance of pebble mother rock of machine-made aggregate. The method comprises the following steps: 1) sampling: randomly selecting representative pebbles; 2) screening: screening the primary pebbles to obtain the particle size distribution of the pebbles; 3) selecting a pebble sample with a specific particle size for testing, ultrasonically testing the pebble sample with the particle size of more than 100mm, and testing the pebble sample with the particle size of 9.5-19mm by adopting a cylinder pressure method; and 4) result analysis and evaluation: analyzing the performance of the pebbles according to a test result so as to evaluate the mother rock performance of the pebbles. Compared with the prior art, the method has the advantages of simplicity, accuracy, advancement, quickness, field application and the like.

AI Technical Summary

Benefits of technology

This patented technology allows researchers to evaluate how well two types of stones have been made from them - one being larger than another type called chisel stone (C) while still having good compression properties. It also includes various techniques like exploring its surface under specific conditions such as water level changes over time during drilling operations. These technical features make these tests faster and easier compared against previous methods used by scientists who had trouble analyzing smaller particles found inside their own natural materials.

Problems solved by technology

Technological Problem: Current assessment techniques involve analyzing the properties of rocks during their production or utilization stages, making them difficult to predict its future needs because they require extensive analysis beforehand. There has been some attempts at developing quicker ways to estimate both compression strength and density levels from existing data sources like geology basins alone.
