The effects of aggregates content, aggregates size, sintering temperature and adding new aggregate on the permeability, apparent porosity, water absorption and mechanical properties of the prepared permeable bricks were systematically investigated.
The influence of water-to-binder ratios, mineral admixtures, aggregates and temperature were systematically investigated.
According to the XRD patterns and the phase diagram, a phase transition of quartz occurred in quartzite and granite aggregates when temperature exceeded 573 °C.
For the CB-filled polymer composites, CB would often re-aggregate when temperature is close to the melting point of polymer matrix, so that the conductive network would be destroyed.
For subsequent analysis, we aggregated weekly temperature values into four-week interval values, by taking the average of the individual weeks' temperature values.
Nearly all contaminating proteins aggregated at temperatures above 50°C, increasing the extract purity 30 – 40%, while GRFT remains stable until the extract reaches 90°C.
Both the single chain and aggregate dimensions are temperature independent, as is the extent of aggregation at a given concentration.
However, catalyst NPs particularly metal NPs tend to aggregate at high temperature.

This indicates that amorphous phases were formed in quartzite aggregate under high temperature.
