What is the best mix for concrete?
In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts aggregates . For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used.
What are different types of ready mix concrete?
- Shrink Mixed Concrete.
- Transit Mixed Concrete.
- Central Mixed Concrete.

What is the classification of concrete?
Classification according to the consistency of concrete
11/87), there are four types of concrete consistency: solid, low-plastic, plastic and liquid . Consistency of fresh concrete is the set of all fresh concrete properties that affect its workability and processability.
What is the strongest concrete mix ratio?
A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate. In pre-mix concrete, the aggregate is already mixed with the cement.
How do you calculate a mix ratio?
Divide 1 by the total number of parts (water + solution) . For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9).
What is the ratio of concrete slab?
A concrete mix of 1 part cement : 2 parts sand : 4 parts coarse aggregate should be used for a concrete slab.
How many bags of cement do I need for 1 cubic meter?
How many bags of cement are needed to mix one cubic meter of concrete? A. One cubic meter of concrete is equal to 1.308 cubic yards of concrete. If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete.
Can you make concrete with just sand and cement?
Can I make concrete with just sand and cement? No, you can't make concrete with only sand and cement . Concrete isn't considered concrete without aggregates like gravel and stone. It's the aggregates that contribute to concrete having high strength.
How do you mix a concrete bucket by hand?
If you need to mix a small amount, for instance half a bucket, place the stone and sand and finally the cement into the bucket. This needs to be thoroughly dry mixed with a garden or block layers trowel. Water is then added, say half a pint at a time and mixed throughout the bucket.
What are the disadvantages of ready mix concrete?
- Requires huge initial investment.
- Not suitable for small projects (less quantity of concrete is required).
- Need an effective transportation system from the batching plant to the job site.
What are the advantages of ready mix concrete?
- Quality and Consistency. ...
- Efficiency. ...
- Environment Friendly. ...
- Convenient Delivery. ...
- Versatility. ...
- Reduced Wastage. ...
- Reduced Life-Cycle Cost.
What is the most common type of concrete?
Standard ready-mix concrete is the most common form of concrete. It is prepared for delivery at a concrete plant instead of mixed on the construction site, which guarantees the quality of the concrete. This type of concrete can provide a structural function, as well as an aesthetic or decorative finish.
