Laboratory and field investigations of recycled portland …
The structure of a portland cement concrete (PCC) pavement is generally composed of a PCC pavement, a granular aggregate subbase, and the subgrade. The subbase and subgrade layers are the main structures that support the PCC pavement. The subbase receives traffic loads from the PCC pavement and transfers and dissipates these loads to …

Stabilization of Clay Soils by Portland Cement or …
Additional C-S-H can form in both the portland cement-soil and lime-soil systems due to the reaction between Ca(OH)2 supplied by either cement or lime and the silica supplied by soil. This process is known as a pozzolanic reaction. Calcium may also react with alumina and produce C-A-H that is cementitious in nature.
