Which method of design of concrete is more economical?

The balanced reinforcement approaches the most economical design for present-day cost ratios and ordinary strength of the concrete. 7. 7. The economy of the reinforcing steel is directly proportional to the ratio between its unit price and yield-point stress.

How do you make concrete economical?

1. Money Making Batching Plants. One of the most effective ways to reduce concrete costs is to manufacture your concrete on site.
2. Cement Replacement. The next method to reduce concrete costs is to look at the input costs of cement, sand and aggregate.
3. Concrete Made from Spoil.
4. Remote Sites.
5. Recycling Mixes.

How do you make a concrete design mix?

Concrete Mix Design Made Easy

1. Step 1: Slump Flow.
2. Step 2: Aggregate Size.
3. Step 3: Mixing Water and Air Content.
4. Step 4: Concrete Strength and Water/Cement Ratio.
5. Step 5: Coarse Aggregate.
6. Step 6: Fine Aggregate.
7. Step 7: Adjustment for Moisture in Aggregates.
8. Step 8: Summary Design.

What are the basic considerations for concrete mix design?

The various factors affecting the choice of concrete mix design are:

• Compressive strength of concrete.
• Workability of concrete.
• Durability of concrete.
• Maximum nominal size of aggregate.
• Grading and type of aggregate.
• Quality Control at site.

What is difference between nominal & Design mix?

It can be defined as the process of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength and durability as economically as possible.

How is nominal mix concrete different from design mix concrete?

The nominal mix is site-level mixing small concrete mixer can be used to mix the ingredients. Whereas the design mix is designed from ready mix concrete plant that is RMC plant.

What is BIS method of mix design?

The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.

How to design concrete mix design?

The main aim of the concrete mix design is to find out the desired proportion of each ingredients which are cement, coarse aggregate, fine aggregate, water etc. to obtain the required properties of resulting mix. 2. Quality Concrete Mix Each ingredient used in the concrete mix design is tested for its quality.

What are the three steps in the concrete mixing process?

There are three phases in the development of a concrete mixture: specifying, designing, and proportioning The most common method used in North America is thatestablished by ACI Recommended Practice 211.1 Any mix design procedure will provide a first approximationof the proportions and must be checked by trial batches.

How can I Optimize my concrete mix?

It’s important to optimize concrete to ensure the lowest cost while maintaining the highest strength of your mixture. This is far from easy, as every addition or subtraction to the concrete mix entails adjustments to the components, making the process very complicated and inefficient. The solution is Giatec’s Concrete Hub app.

What is water/cement ratio in concrete design?

The water/cement ratio is the most important parameter of the concrete mix design; it governs the strength, durability, and workability of the concrete mix. Here, you will need to enter the required compressive strength and associated water/cement ratio.
