Project description
I am exploring the impact of calcite bonding and clay content on the collapse potential of soils. I am focusing on collapsible fine-grained calcareous soils.
I will explore the potential of a well-selected silicate solution applied by single-step method. This will effectively mitigate collapse, as well as improve strength in these collapsible soils.
We will create calcareous samples using an innovative laboratory method of calcite precipitation. We will study the dissolution effect of the calcite bonding on collapsibility. We use oedometer testing and relate compressive strength to collapsibility.
