MATERIALS AND METHODS Materials To perform the stages described in this work, we used the following clay samples: Gray Clay, Clear Clay, Green Clay and Dark Bentonite Clay, coming from deposits located in the District of Pedra Lavada-PB.
Next, they were processed in a ball grinder, internally covered with ceramic material of high hardness, for comminution.
After the comminution, the material was sieved in ABNT sieve no. 200 (0.074 mm) using an electric sieve model I-3007, of the Pavitest brand.

Self-compacting concrete mixing materials are obviously different from ordinary concrete, and various mixing materials must be carefully selected to meet various specifications of self-compacting concrete.
The properties of each material are shown in Table 2 to Table 7.

So the rail transit not only brings about streams of people, but also facilitates the accessibility of land along the rail line. (3)Industrial land: Except the need of work, a much smaller amount of people is related to, in terms of industrial land, and transportation of materials employed here mostly don’t depend on rail transit ,thus, it is apt to be “discarded” into the urban location away from the rail transit. (4) Land for external traffic: The close connection between this type of land use and urban external flow of people requires a benign link among the inner public transportation.
