Technology of aggregates
These techniques are used to characterize and evaluate aggregates used in civil engineering projects.
The CTMP has the equipment and the know-how to perform :
- Sampling
- Sieve analysis
- Determination of physical properties
- Chemical analysis
- Seeking for new markets
A number of our testing units are practically exclusive such as the Polishing-by-Projection Coefficient (CPP) equipment, with which we can measure the resistance to polishing of an aggregate to be used in road construction
Aggregate properties are measured following BNQ standard test procedures: Micro-Deval, Los Angeles, Polishing-by-Projection Coefficient (CPP).
In our chemistry lab we can measure the neutralizing power of limestone for agriculture usage. Atomic absorption equipment is also used to determine the chemical composition of aggregates.
Following are some examples of projects performed on aggregates:
Research for new utilization of quarry stocks in different products
Within this project the CTMP found new markets for many types of quarry aggregates other than the traditional uses such as for road construction, concrete and asphalt.
Determination of the Polishing-by-Projection Coefficient of aggregates
In 1996 the Quebec Department of Transport introduced a new test to measure the resistance to polishing of aggregates used in asphalt for roads. The study aimed to determine how the different type of rocks found in the Province reacted to polishing. The study also looked at the possibility to mix different types of rocks to meet the criteria set forth by the Department of Transport.
