Why is ready mix concrete required in place of on site mixing of concrete?

That requirement is not true of all jurisdictions. In many areas you can mix onsite if you wish. There may have been lobbying by environmental groups or even cement companies to cause this requirement in your area.
The point is why would you mix onsite? Unless you have a very small job or great distance to transport the cement to the job, it is more efficient, cheaper, and cleaner to use ready mix.
It is cost effective.
Some construction site require site mixing just to save time and money.

What is the difference between leAn concrete and ready mix concrete?
Lean mix concrete is used for substructures like foundations,piles,etc.,Ready mix concrete is used for superstructures and also for mass construction.Generally, quality of ready mix concrete is good when compared to the lean mix concrete.Workability of lean mix concrete is high when compared to RMC.

Can Grade 25 ready mix concrete be used for a roadway?
It can be used, provided you know the maximum weight on vehicles on it. From experience, 30 ton trailers can run comfortably on a 200mm thick g-25 concrete mix..
How do I put in a concrete driveway?
Dig out app. 10 inches of soil. Fill 6 inches of hardpack (crushed concrete). This is for drainage and frost heave prevention. Bring in the concrete truck after renting floats and trowels and building frame. The whole driveway should be surrounded by 1X wood or PVC particle board sprayed with wd 40. The side of the 1X facing away from the concrete should have spikes in the ground and fastened to the board. You level the concrete to the top of these boards. It's like a big frame surrounding the project and you should take your time in building it, for level, runoff and evenness. Have a wheelbarrel and a few extra hands ready (the driver charges by the minute after a certain amount of time). The concrete should be fiber reinforced mix. This type eliminates the need for metal screening or fencing over the hardpack and suspended in the concrete for strength. Be advised, if you're in a snowy region, salt will be your only advisary, don't use it, salt eats concrete. You also need to put in stress gaps from side to side every 8 feet or more depending on width. When the concrete cracks it will crack along these lines. You do this when the concrete starts setting up but is still soft. Finish trowel all the edges. Screen the concrete with a long board across the width (from board top to board top and then use the float to smooth it. Keep a few wheel barrells full of concrete ready so you can get rid of the truck and still have concrete for leveling and fill after a majority of the concrete has been shovelled in. A tool rental agency may have tips and advice also.
What is enabling works in construction?
Its the preparation of a site ready for the first stage of development (e.g. Perimeter fencing, access routes, safety signage etc.) It may also include some preliminary construction works (e.g. groundworks). The result is a site that is ready and equiped for the main body of works to begin.
What is ready mix concrete?
concrete ingredients are directly feed in to the mixture plant and mixing done by means of machine. And it is pumped by means of concrete pump and placed in the site.
What is concrete quantity?
It is typically measures in cubic yards. Anything over 2 cubic yards is a lot of mixing, so you'd likely want to order that from a concrete company in a ready mix concrete truck.
What is better RMC or Concrete Mixer?
The foremost difference between RMC or Ready Mix Concrete machine and conventional concrete mixer, is in its portability factor. Ready mix concrete machine or in-transit concrete mixers are used in places where it is not feasible to prepare concrete at construction site. For small and medium sized projects the cost of purchasing and storing ingredients of concrete, hiring of labour may not prove worthwhile, in comparison, to the more cost effective, in-transit concrete mixer. Ready mix concrete machine can carry preweighed payload of, sand, gravel, cement and aggregates. They may only require to consume water from a source near the site before they deliver the final product. The payload of an in-transit concrete mixer often consists of sand, gravel, cement(portland or any other) along with optional ad-mixture. To delay the setting time of concrete often retarders are used. The term Ready mix concrete or in-transit concrete mixers are interchangeably used for machines which are used to carry ingredients of concrete in a plastic state to the site. However, concrete mixer machine is an equipment that homogeneously combines ingredients of concrete like sand, gravel, cement and water along with aggregates. Medium and large size construction projects requires concrete mixers of varying capacities that are equipped to prepare concrete at construction sites giving workers ample time to work before the concrete hardens. A typical concrete mixer consists of a conventional revolving drum that mixes ingredients of concrete based on Archimedes Screw principle. What are the different types of concrete mixers: Based on the key feature, drum, concrete mixers can be categorised into two different types, tiltable drum concrete mixers, which are more commonly called as 10/7 Concrete Mixers, and Reverse Drum Concrete Mixers. 10/7 concrete mixer got its name from 10 cubic feet of input ingredients, producing an output of 7 cubic feet of concrete. Whereas reverse drum concrete mixers are used in places that require, comparatively a bigger output. However, it may be noted that today’s construction industry increasingly requires homogeneity, consistency and short mixing times in production of concrete. Different types of stationary or portable concrete mixers have evolved over the period of time that has caused refinement of mixing technologies in concrete production. Different types of concrete mixers can be broadly classified into two types: ● Twin Shaft concrete Mixers which are known for their high intensity mixings along with short mixing times. ● Pan-mixers that are driven by planetary gear-box are used where concrete is required usually in high volume with input ingredients, weighed more accurately. ● Tiltable drum or Reverse drum concrete mixers, where production is required in high output volume. The debate over ready mix concrete and conventional concrete mixer is often not inconclusive since, it may be noted that ready mix concrete has limitations over a conventional concrete mixer. Concrete as a product has limited & short lifespan that ranges between stages like batching / mixing/ curing.That quintessentially, mean ready mixed concrete must be placed within a maximum of 35-40 minutes of batching process, and in addition to it, in-transit mixing can be allowed upto 2 to 3 hours at the most. Admixtures and retarders can buy some more time before the setting process kicks in. Nonetheless, there are no such limitations for portable or stationary concrete mixers. So functionality of concrete mixers, will at all time, prevail and precede, over ready mix concrete. Conclusion:- ● In conclusion, Jaypee is a reputable brand in the construction industry. They offer a wide range of concrete mixers that are suitable for different types of construction projects. Their mixers are designed to be durable, efficient, and easy to operate. ● It ensures proper material mixing. ● Where site mixing is required, concrete mixers invariably hold more preference than ready-mix concrete for a steady supply of concrete mortar. Jaypee's revolutionary concrete mixers have consistently outperformed other concrete mixers in longevity, and consistency of concrete as output. ● RMC is only recommended for very limited projects requiring a small amount of concrete since consistent concrete production in large volumes is difficult to achieve by RMC machines.
Where can one buy a concrete ready mixed?

What is concrete pump?
Concrete Pump is an equipment mounted on a Truck Chasis, which does the job of Mixing the cement Mortar and delivering the same at work site as ready Mix concrete. Since the mortar mix can directly be poured or pumped to cast the slab or column or any other structural component, it is termed as Concrete Pump please visit the URL : - http://www.concretepumps.com for further reference.
Mold measuring 11.5 x 6 x 2.5 How many can I fill with a 80 lb bag of ready mix concrete?
The answer depends on the measurement units used for the mould. The amount of concrete required if the measurements are in metres will be approx 35 times as large compared to the amount required if they are in feet!
