| Abstract |
| Two soil samples from A gartala were studied for their suitability for high
strength bricks. The soils are highly siliceous in nature and contain illitic group of
clay minerals. Bricks from these soils crack during firing. Paving bricks of 500-
520 kg I sq em strength, 4 to 5 per cent water absorption and possessing high abrasion
resistance can be developed from these soils at a firing temperature of /050° -JJOOoC
and at a controlled heating and cooling rate of 20oC I hour. Quartz inversion and
overall expansion are considered responsible for cracking in bricks. |
