What are the factors affecting the compressive strength of concrete?

What are the factors affecting the compressive strength 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.

What are the main factors affecting the compressive strength of masonry?

The compressive strength of masonry depends on several factors such as: mortar strength; unit strength; relative ratio between the mortar and unit strength; relationship between the height of the unit and the smaller horizontal dimension of the unit; orientation of the unit in relation to the direction of the load …

What are the factors affecting strength and elasticity of concrete?

8 Factors Affecting Modulus of Elasticity of Concrete

• Strength of Concrete.
• Cement Paste.
• Aggregates.
• Concrete Wetness Condition.
• Transition Zone.
• Mix Proportion.
• Concrete Age.
• Curing Regime.

What is the most important factor that affects the strength of the concrete mix?

1. Water/cement ratio. Water to cement ratio (W/C ratio) is the single most important factor governing the strength and durability of concrete. Strength of concrete depends upon W/C ratio rather than the cement content.

What are the factors affecting the strength of brick?

Factors that injluence the bond strength between brick and mortar include: the age of the specimen, curing conditions, the jlow of the mortar and the composition of the mortar.

How is compressive strength of concrete determined?

The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units.

Why is compressive strength of concrete determined?

The Compressive strength of a material is determined by the ability of the material to resist failure in the form of cracks and fissure. In this test, the impact force applied on both faces of Mortar specimen made with Cement and the maximum compression that cement specimen bears without failure recorded.

How do you increase the strength of a brick wall?

To prevent the collapse of masonry walls during earthquake, it is advisable to use reinforced brick masonry walls in new construction. Existing masonry walls can also be strengthened by providing reinforced concrete jackets on one or both sides of the walls.

What are the factors that affect the strength of concrete?

In general, cement is considered one of the highly influential factors affecting strength of concrete. Aggregate is the material bond with the cement paste after reacting with water. Therefore, the quality of the aggregate effect on the strength of concrete.

How to determine compressive strength of concrete?

Depending on the water-cement ratio, the compressive strength is defined in the mix designs. When we required a certain grade of concrete, firstly we select an appropriate water-cement ratio to proceed with the mix design. As indicated in the above figure, the increase of the water/cement ration reduces the compressive strength of the concrete.

What is the ratio of water to cement in concrete?

The ratio of the weight of water to the weight of cement is called Water/Cement ratio. It is the most important factor for gaining the strength of concrete. The lower w/c ratio leads the higher strength of concrete. Generally, the water/cement ratio of 0.45 to 0.60 is used.

What is the compressive strength of geopolymer concrete?

The compressive strength of geopolymer concrete is inversely proportional to the water-togeopolymer binder ratio similar to that of waterto- cement ratio in cement concrete. Suitable range of water-to-geopolymer binder ratio is in the range of 0.25 to 0.35.
