for good structural stone crushing strength should be greater than

This means that the bar can have a yield strength greater then that but never less For example #3 rebar has a minimum yield strength of 6 600 pounds The minimum yield strength of #4 rebar is (11 780 lbs ) 78% greater However the diameter of #3 rebar is only 1/8-of-an-inch less than that of #4 rebar — 3/8-inch versus 1/2-of-an-inch respectively In other words increasing the diameter

HOW AGGREGATE PROPERTIES AFFECTS CONCRETE

The nominal maximum size of coarse aggregate should be as large as possible within the limits specified but in no case greater than 1/4th of the min thickness of the member For most works 20 mm aggregate is suitable 40 mm and 10 mm size should be used for work specified Plums above 160 mm should be used when specifically permitted in

A good building stone must have a specific gravity greater than 2 7 A good stone must have a compact fine crystalline structure strong and durable A good stone should not absorb water more than 0 6 percent by weight A good building stone must be acid resistant and free from any soluble matter (2) Uses of stones Stones are used In the construction of buildings For foundations walls

Qualities of a good building stone Crushing strength For a good building stone the crushing strength should be greater than l000kg per cm2 Appearance Good building stone should be a uniform colour and free from clay holes spots of other colour bands etc capable of preserving the colour for longtime Durability A good building stone should be durable The factors like heat and cold

Compressive Strength Test of Bricks The determination of Compressive Strength Test of Brick is carried out under the specification of ASTM C67-03 Sampling of Brick Selection of Test Specimen Full-size representative bricks should be sampled randomly to cover the whole range color texture and sizes from a shipment

Reinforced Concrete is a structural material is widely used in many types of structures It is competitive with steel if economically designed and executed Advantages of reinforced concrete Reinforced concrete also has greater compressive strength as compared to most other materials used for construction besides good in tension

8 STRENGTH OF SOILS AND ROCKS shear stress is the shear strength of the soil for the particular value of the normal force N or normal stress NA applied to the soil where A is the cross sectional area of the soil sample Fig 88 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement

Aggregate Crushing Value Test

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions

REQUIREMENTS OF A GOOD BUILDING STONE - The Constructor Strength Ordinarily the strength of a stone is not of primary importance as very it is subjected in a structure are much below its permissible crushing strengthThe specific gravity of good building stones should be
