What is concrete mixing ratio in M 40 concrete?
M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.
How big is a bag of concrete?
Usually concrete mix comes in 40, 60 or 80 pound bags.
What is the compressive strength of M40 concrete?
40 MPa
What is the density of reinforced concrete grade 40?
The density of reinforced concrete is 2500 kg/cum or 25 kn/cum
How much would 40 cubic feet of concrete cost?
40 / 27 = 1.481 yards x $100 = $148.00 + tax. Unfortunately you will have a hard time getting a concrete company to deliver less than 5 yards.

What is C-40 grade of concrete used for?
Constructions that require the concrete to withstand 40 Newtons of compressive force.
What is C40 concrete?
The concrete that gives a compressive strength of 40 N/mm2 when its cube is tested.

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.

What is the equivalent of c-40 concrete in to psi?
C-40 concrete has a characteristic compressive strength of 40 MPa (megapascals). To convert this to psi (pounds per square inch), you can use the conversion factor where 1 MPa is approximately equal to 145.038 psi. Therefore, C-40 concrete is equivalent to about 5,800 psi.
