NICE Construction Materials Question Paper
Part – A :
1. What is a stone? :
The stone is always obtained from rock. The rock quarried from quarries is called stone. Quarried stone may be in the form of stone blocks, stone aggregate, stone slabs, stone lintels etc.

2. How are rocks classified? :
The rocks may be classified in the following 4 ways.
i. Geological classification
ii. Physical classification
iii. Chemical classification
3. What are the geological classification of rocks? :
i. Igneous rocks
ii. Sedimentary rocks
iii. Metamorphic rocks
4. What ere the physical classification of rocks? :
i. Stratified rocks
ii. Unstratified rocks
iii. Foliated or laminated rocks
5. What are the chemical classification of rocks? :
i. Silicious rocks
ii. Argillaceous rocks
iii. Calcareous rocks
6. How are igneous rocks classified? :
Volcanic igneous rocks eg. Basalt
Hypa-bysal rocks eg. Dolerite
Plutonic rocks eg. Granite
7. Give some examples of sedimentary rocks.
Sand stone, limestone, Lignite, slate and shale
8. Give some examples of metamorphic rocks.
Marble, Laterite, Gneiss
9. Give some examples of silicious, argillaceous and calcareous rocks.
Silicious rocks – Granite, quartzite, trap, basalt, sand stone
Argillaceous rocks – Laterite, slate
Calcareous rocks – Limestone, marble, dolomite, kankar
10. Name some hard and soft rocks.
Hard rocks – Granite, basalt, trap gravel, quartzite
Soft rocks – Talc, gypsum, sandstone, slate
11. What are rock forming minerals? :
Chemically the rocks are composed of mineal earths, alkalies, oxides of iron and manganese etc. Silica (SiO2). alumina (Al2O3), lime (CaO), and magnesia (MgO) are the mineral earths, which are usually found in rocks in one form or the other. Soda (Na2O) and potash (K2O) are the usual alkalies present in the rocks.
12. What is meant by texture of rocks? :
The way the particles of rock forming minerals, are arranged in the rocks is termed as texture or structure of the rock.
13. What are the different forms of textureof the stone? :
Compact crystalline, Granular crystalline, Conglomerate, Glass texture, Folited texture, Porous granular, Vesicular texture
14. What are the types of fracture of rocks? :
i. Uneven
ii. Even
iii. Conchoidal
iv. Fibrous
15. What are the uses of stone? :
** For masonry work
** For lintels and vertical columns
** For covering floors and buildings
** For paving of roads and footpaths
** As an aggregate in cement as well as lime concretes.
16. What is known as natural bed of stone? :
The rocks particularly sedimentary type, have distinct plane sof division along which stones can be easily split. The plane along which stones can be easily split is known as natural bed of stone.
17. What are the various tests for stones? :
1. Smith’s test 6. Microscopic examination
2. Freezing and thawing test 7. Impact test
3. Frost action test 8. Attrition test
4. Acid test 9. Crushing test
5. Water absorption test 10. Hardness test
18. what are the causes for deterioration of stones? :
1. Temperature variation 6. Vegetable growth
2. Wetting and drying of stone 7. Rain water
3. Frost action 8. Wind
4. Polluted atmosphere 9. Water
5. Living organisms 10. Chemicals
19. What is an artificial stone? :
Cast stone or artificial stone is nothing, but hardened plain cement concrete, moulded in suitable shape and size. Artificial stone consists of 1.5 parts of coarse aggregate of size 3mm to 6mm and 1.5 parts of coarse aggregate of size less than 3mm.
20. What are the advantages of artificial stones? :
** They can be cast in any shape and size.
** They can be made stronger than natural stone.
** They can be easily moulded and seasoned at the site of work.
** They donot require any dressing.
** They can be designed for any strength.
