How the functionality of concrete is affected by the different factors
Quantity of water
Grading of aggregate
Shape of aggregate
Texture of aggregate
Ratio of concrete
QUANTITY OF WATER.
Water is considered as the most vital factor that can influence the functionality of concrete. If more water is added, the functionality of the concrete will be enhanced. But with the inclusion of too much water, the durability of concrete can be reduced.
SIZE OF AGGREGATES
If the size of the aggregate is increased, the functionality of the high strength concrete will be reduced whereas the functionality of normal strength concrete is raised with the increment in the size of the aggregates.
GRADING OF AGGREGATES
If the grading of the aggregates is superior, the strength of the concrete along with the functionality is enhanced. The functionality of the concrete becomes superior with least number of voids. As for example, if there are 5%viods, the strength of the concrete will be reduced by 30 percent.
SHAPE OF AGGREGATE
The functionality of concrete is influenced by the shape of aggregate. The cubic shaped aggregate is mostly recommended. The functionality of the concrete is greatly affected by the stretched and odd shaped aggregate. The longevity of such concrete is also decreased. The functionality of the concrete is increased if the concrete contains rounded aggregates. But in this situation, the bond of the concrete remains extremely weak.
TEXTURE OF CONCRETE
Texture of aggregate is another crucial factor to influence the functionality of concrete. In order to develop a concrete, porous aggregate needs more water and thus the functionality of concrete is reduced.
RATIO OF CONCRETE
The functionality of concrete is also influenced by the ratio of fine aggregates and the course aggregate. If the number of fine aggregates in concrete is increased, the functionality of the concrete becomes superior. As for example, if the quantity of the cement is increased, the functionality of the concrete enhances.
