The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.

Why is it important to have workable concrete?

simply workabilty is the w/c ratio in concrete. more the w/c ratio higher the workability and vice versa. and it is true that excess amount of w/c ratio doesnt give proper strength. so workable concrete i.e, concrete with proper w/c is must for good strength. *note: not considering the mix of concrete.


What is the difference between concrete grade and concrete strength?

concrete grade and strength are both revalent since if grade increase setting time will be less and curing to be done propely so that concrete strength will reach higher. If concrete grade is low curing to done longer days upto intial setting time to reach proper strength


Why is concrete so important?

Concrete is essential due to its durability, versatility, and cost-effectiveness, making it a foundational material in construction and infrastructure. It can be molded into various shapes and sizes, allowing for innovative architectural designs and applications in buildings, roads, bridges, and more. Additionally, concrete has a high compressive strength, enabling it to support heavy loads and withstand environmental stresses. Its widespread use contributes significantly to urban development and economic growth.


What does it mean if you measure concrete strength to be 50 MPa?

The units of Mpa is N/mm2 so this means that the concrete can resist a compresion forse of 50 newtons spread over 1 mm2 *Note if this value is a measured value a safety factor needs to be applied if it is to be used in construction, this factor are specified in you country's design code


Why steel is used to reinforce concrete explain it?

There are two main loading conditions that concrete under goes. These are Compression and Tension. Concrete is very strong in compression and is very weak in Tension (pulling apart). Concrete has so little strength to resist tension it is assumed to have no strength in tension. When civil engineers design concrete structures they can determine where the tension and compression will be located. Steel is added to give the concrete tensile strength. For Example a concrete beam when loaded from the top will experience compression on top section of the beam. The top portion of the beam will push inwards creating compression while the bottom section will pull apart creating tension. (Imagine a smile shape). :) Therefore reinforcement will be needed in the tension area (bottom).

What is the grade of concrete?

The grade of concrete refers to its compressive strength measured in megapascals (MPa) or pounds per square inch (psi) after 28 days of curing. Common grades include M15, M20, M25, and so on, where the number indicates the characteristic strength of the concrete mix. Higher-grade concrete has a greater strength, making it suitable for structural applications requiring durability and load-bearing capacity. The selection of the appropriate grade depends on the specific requirements of the construction project.

What is the full meaning of B R C in construction and uses?

In construction, BRC stands for "British Reinforced Concrete," which refers to a type of steel reinforcement mesh commonly used in construction projects to provide structural strength to concrete elements such as slabs, walls, and columns. The BRC mesh is manufactured by welding together high-strength steel wires in a grid pattern, creating a durable and flexible material that helps distribute loads and prevent cracking in concrete structures. The use of BRC mesh in construction helps improve the overall integrity and longevity of the concrete elements, making them more resistant to stresses and deformations.

What is curing of concrete?

The curing of concrete is a reaction between the type of cement in the concrete and the water. This reaction between cement and water is known as hydration. When the concrete sets and gains strength through this process it is known as curing. Test cylinders of concrete for construction projects are placed in a curing room where they are continuous misted with water at 23 +-2 degrees Celsius for 7 and 28 days before testing. This provides adequate curing.


Why iron metal is used in building construction?

It deals with the tension and compression of the concrete. Concrete is a really great material when in comes to compression. It has a high strength in compression but little in the way of tension. You can test this for your self. Get a small unreinforced piece of concrete and pull it apart it ( put it in tension) and it breaks fairy easily. Now, try pushing together (put it in compression) and it doesn't break anywhere near as easily, if you can break it at all. Steel is the opposite. It has more strength in tension than in compression. Putting steel bars in concrete allows you to have good strength in compression and in tension. In an easy way to understand it and get the general idea, when the reinforced concrete is under tension, the steel bars take over, and when the reinforced concrete is under compression, the concrete takes over.

Which Roman accomplishment was most important written laws aqueducts cement widespread use of arch roads or a calendar?

In the list of Roman accomplishments you mention, there was not one that can be singled out as the "most important". They all had different purposes so they were all important in their own areas. The laws were important in the civil area, the aqueducts in the health area, the concrete and arches were important in the construction area, the roads in transportation and the calendar in the time and record keeping areas.In the list of Roman accomplishments you mention, there was not one that can be singled out as the "most important".

Why are there cracks on concrete paths?

Concrete has great compressional strength but very weak torque resistance. That means when the ground underneath concrete paths settles or erodes the concrete will crack. In order to determine where the concrete will crack the constructors leave faults in it. So when the concrete does crack it does so in such a manner that the path is still functional and aesthetic.

What was the key to the support of the Colosseum in Rome?

Concrete and the vaulted arches were keys to the support of the Colosseum. It was built with a mixture of concrete and stone. The Romans were in the middle of developing concrete and were unsure of its strength and durability, so they used stone as well. Roman concrete proved to be very strong and long lasting and it is mainly due to this that it has survived. Moreover, unlike stone, it cannot be quarried to be used as building material elsewhere, which is the main reason why so many Roman buildings are in ruin. The great load-bearing strength of the vaulted arch was also very important in supporting the Colosseum.


What is difference between MS rods and TMT bars?

TMT Bars - High strength deformed steel bars used for concrete reinforcement. The surface has many short ribs to allow the concrete to adhere better than if the bars had a smooth surface.MS Rods - Mild Steel rods are used to construct many things (such as scaffold construction), but are not the best choice for concrete. The surface of the rod is smooth, so it does not allow the concrete to adhere as well as if the surface had a texture.
