The municipal district of Santa Maria presents an enormous deficiency in the attendance to the popular home, with poverty areas n busy for sub-houses, many irregular times.

For so much they studied lines, in weight, of 1/10, 1/12, 1/14 and 1/16, of cement in relation to the soil, these considered viable for production of solid bricks. At the end it was verified that the line of 1/10 just produced satisfactory results for the production of bricks, being considered cures for 7 days, although all the materials presented with rest absorptions below the allowed maxims.
