Portland cement is the most common hydraulic cement used in concrete on NCDOT projects. It is composed primarily of calcium silicates, with a smaller proportion of calcium aluminates. By definition, the composition of portland cement falls within a relatively narrow band. Portland cement is made primarily from four elements calcium, silica ...
Cement concrete tiles and paving blocks are precast solid products made out of cement concrete. The product can be made in various shapes and sizes as per the requirement. These blocks are generally interlocking type and are mostly adopted for paving open surface to facilitate easy movement and for convenience in walking.
