Properties of stones:

structure , texture , density , appearance , strength , hardness , percentage wear , porosity and absorption , weathering , toughness , resistance to fire , ease in dressing , seasoning

2

The ______ of the stone may be stratified (layered) or unstratified. ______ stones should be easily dressed and suitable for super structure

structure

3

Fine grained stones with homogeneous distribution look attractive and hence they are used for carving

texture

4

______ stones are stronger, light weight stones are weak, hence stones with specific gravity less than 2.4 are considered unsuitable for buildings

density

5

A stone with uniform and attractive colour is durable, if grains are compact

appearance

6

______ is an important property to be looked into before selecting stone as building block

strength

7

It is an important property to be considered when stone is used for flooring and pavement

hardness

8

It is measured by attrition test. It is an important property to be considered in selecting aggregate for road works and railway ballast. A good stone should not show wear of more than ______

percentage wear , 2%

9

All stones have pores and hence absorb water, the reaction of water with material of stone cause disintegration

porosity

10

______ test is specified as percentage of water absorbed by the stone when it is immersed under water for 24 hours For a good stone it should be as small as possible and in no case more than ______

absorption , 5

11

Rain and wind cause loss of good appearance of stones, hence stones with good weather resistance should be used for face works

weathering

12

The resistance to impact is called ______

toughness

13

According to impact test, stones with toughness index more than ______ are preferred for road works

19

14

Toughness index ______ are considered as medium tough and stones with toughness index less than ______ are poor stones

13 to 19 , 13

15

Dressing is easy in stones with lesser strength, hence an engineer should look into sufficient strength rather than high strength while selecting stones for building works

ease in dressing

16

The process of removing moisture from pores is called ______

seasoning
