What are the factors affecting durability?
Factors Affecting Durability of Concrete
- Cement Content.
- Aggregate Quality.
- Water Quality.
- Concrete Compaction.
- Curing Period.
- Permeability.
- Moisture.
- Temperature.
Which of the following factors affect the durability of a stone?
Stone durability is dependent on its composition, which can affect strength and appearance, and environmental exposure factors. Even though a particular stone may be thought of as uniform, it is still a natural material with varying composition and physical properties.
What is the durability of a rock?
Durability of rock can be defined as the rock’s ability to resist degradation during its working life, whereas weathering can be defined as the process of alteration of rock due to the natural agents such as air, water, organic fluids etc.
What factors affect the rocks that form?
igneous rock rock that forms when magma cools and solidifies.
What is durability and what are the factors affecting durability of concrete?
Concrete durability gets affected when there is a chance of penetrability of water into it. Permeability of water into concrete expand its volume and lead to formation of cracks and finally disintegration of concrete occurs. Generally concrete contains small gel pores and capillary cavities.
What are the factors affecting strength and durability of concrete?
Factors Affecting Strength of Concrete
- Quality of Raw Materials.
- Water / Cement Ratio.
- Coarse / fine aggregate ratio.
- Aggregate / Cement Ratio.
- Age of concrete.
- Compaction of concrete.
- Temperature.
- Relative humidity.
Which of the following factor affect the durability of concrete?
Permeability: It is considered the most important factor for durability. It can be noticed that higher permeability is usually caused by higher porosity. Therefore, a proper curing, sufficient cement, proper compaction and suitable concrete cover could provide a low permeability concrete.
How can you tell if a rock is durable?
There are well-established tests for the resistance of rocks to physical weathering due to porosity and fissures, like freeze-thaw cycles; these include the Quervain test using the crystallization pressure of sodium sulphate decahydrate (Quervain and Jenni, 1945) and the Brazilian test for tensile strength.
What is slake durability test?
A test is described that measures the resistance of a rock sample to weakening and disintegration resulting from a standard cycle of drying and wetting. The main purpose of this ‘slake-durability test’ is to evaluate the weathering resistance of shales, mudstones, siltstones and other clay-bearing rocks.
What is the main factor that affects the texture of an igneous rock?
cooling rate
The main factors that can affect the texture of an igneous rock are the location and cooling rate of the hot magma that forms the rock.
What are different factors that affect the texture of igneous rocks?
The texture in igneous rocks depends on the following four factors: i) Viscosity of magma ii) Rate of cooling iii) The order of crystallization of the constituent minerals. iv) The relative rates of growth of the constituent minerals.
