Steel produced by open hearth process is milder than that obtained by the Bessemer process
Engineers prefer open hearth steel for structural purpose as it is more homogenous
Basic Bessemer process is suitable for converting poor ore containing a large proportion of sulphur and phosphorus into steel
All the above
Corrugated sheet iron is made by passing plain sheets between grooved rollers
Strength and stiffness of corrugated sheets are considerably increased
Corrugated sheets are generally used on slanting roofs

The lime in excess makes the cement unsound and causes the cement to expand and disintegrate
The silica in excess makes the cement stronger but its setting time also increases
The excess amount of alumina weakens the cement

Adding 5% to 6% of moisture content by weight, increases the volume of dry sand from 18% to 38%
The bulking of fine sand is more than that of coarse sand
If the percentage content of moisture exceeds 10%, increase in bulk of sand starts increasing
All the above
Quick lime is obtained by burning pure lime stone
Hydraulic lime is obtained by burning lime stone containing clay 5% to 30%
Poor lime is obtained by burning lime stone containing impurities more than 5%
All the above
