The M25 or London Orbital Motorway is a major road encircling most of Greater London, The 117-mile (188-kilometre) motorway is one of the most important roads in the UK and one of the busiest. Margaret Thatcher opened the final section in 1986, making the M25 the longest ring road in Europe upon opening.

- The Dartford Crossing completes the orbital route but is not classed as motorway; it is classed as a trunk road and designated as the A282,
- In some cases, including notable legal contexts such as the Communications Act 2003, the M25 is used as a de facto alternative boundary for Greater London.
- In the 1944 Greater London Plan, Patrick Abercrombie proposed an orbital motorway around London.

This evolved into the London Ringways project in the early 1960s, and by 1966, planning had started on two projects, Ringway 3 to the north and Ringway 4 to the south. By the time the first sections opened in 1975, it was decided the ringways would be combined into a single orbital motorway.

The M25 was one of the first motorway projects to consider environmental concerns and almost 40 public inquiries took place. The road was built as planned despite some protests that included the section over the North Downs and around Epping Forest which required an extension of the Bell Common Tunnel,

Although the M25 was popular during construction, it quickly became apparent that there was insufficient traffic capacity. Because of the public inquiries, several junctions merely served local roads where office and retail developments were built, attracting even more traffic onto the M25 than it was designed for.

## What is the normal mix of M20?

M20 grade of concrete mix ratio – M20 grade concrete ratio is nominally about 1:1.5:3, made of mixture of cement, sand (fine aggregates) and course aggregate in which one part of cement mixed with one parts of sand and two parts of aggregate and water cement ratio is kept between 0.4 to 0.6.

M20 concrete ratio for 1 cubic meter is about 1 cement: 1.5 sand: 3 aggregate (1:1.5:3) are made up of about 403kg (8bags of 50kg) cement, 666 kg sand, 1332kg aggregate and about 220 litres of water and 100kg of steel embedded in case of RCC and water cement ratio is kept between 0.4 to 0.6. M20 concrete mix ratio:- M20 concrete mix ratio is 1:1.5:3, made of mixture of cement, sand and aggregate in which one part is cement, 1.5 part is sand and 3 part is aggregate or stone.

It means 1 bag of cement mixed with 1.5 bag of sand and three bag of aggregate to make concrete mix of M20 grade of concrete.

#### What is M20 strength?

Characteristic strength of M20 concrete is 20 MPa.

#### How do you convert m3 to cement bags?

How To Calculate Cement Bags In 1 Cubic Meter

- Let us consider the nominal mix is 1:2:4
- Loss of cement is considered as 2%
- The output of mix is considered as 67%

To achieve 1 cum output, we need 1/0.67 = 1.49 say 1.50 cum dry mix. Now add the wastage of 2%, i.e (1.50 + 0.02) = 1.52 cum.

- Volume of cement = (cement/cement+sand+aggregate) × Total material
- =(1/1+2+4) × 1.52
- =0.2171 cum
- As we know, the density of cement is 1440 kg/cum and
- Weight of 1 bag cement = 50 kg.
- Therefore volume of 1 bag cement = 50/1440

=0.0347 cum. ∴ No. of cement bags required in 1 cubic meter = 0.2171/0.0347 = 6.25 bags. Note: You can use the same formula for calculating cement for other nominal mixes. Join Telegram Channel – : How To Calculate Cement Bags In 1 Cubic Meter

#### Which is better M10 or M20?

The newly launched Galaxy M10 and M20 offer a similar design language with Infinity-V displays, but they differ in hardware. Here’s what’s similar and different between the two phones. – : Samsung on Monday announced a brand new affordable series in India as the company attempts to win back the market from the hands of Xiaomi, Nokia and others. The Galaxy M series has been launched with an aim to attract millenials by with attractive new Infinity-V displays, long-lasting battery and ultra wide-angle camera.

The Galaxy M10 and M20 () are similar in design, but they offer a few differences in specs as the former falls in the sub-Rs 10,000 segment, while the latter falls in the sub-Rs 15,000 price bracket. We take a look at what sets the two phones apart to help you understand which of the two new Galaxy M phones makes the most sense for you.

– Talking about the price first, the Galaxy M10 is the more affordable of the two phones with a price tag starting at Rs 7,990 and going up to Rs 8,990. The M10 comes in two variants – 2GB + 16GB and 3GB + 32GB. The Galaxy M20, on the other hand, starts at Rs 10,990 and goes up to Rs 12,990.

It also comes in two variants – 3GB + 32GB and 4GB + 64GB. Both the phones support storage expandability up to 512GB via a microsSD card. – The Galaxy M10 and M20 are the first Samsung phones to rock the new Infinity-V displays. This means both the phones offer waterdrop notches on the display, allowing for fewer bezels all around and a large screen-to-body ratio.

From the front, both the phones look identical, but there is a difference in resolution. The Galaxy M10 offers a 720p HD+ display, while the M20 offers a 1080p FHD+ display. Both the phones support Widevine L1, so you will be able to stream videos on popular platforms in true HD, although the M20 will offer better clarity and sharpness. – The Galaxy M20 is also the only phone (and the first-ever Samsung phone) to house a large 5,000mAh battery. Samsung guarantees a two-day battery life on this phones, and our review reaffirms this promise. The Galaxy M10 comes with a smaller 3,400mAh battery, which should be decent enough for an entry-level smartphone.

- The M20 is also the only one among the two to support up to 15W fast charging.
- The Galaxy M20 gets a rear-mounted fingerprint sensor in addition to face unlock.
- The Galaxy M10 offers no physical fingerprint sensor, just the face unlock feature for biometric, which may not work well in low-light.
- The Galaxy M10 and M20 come with different processors as well.

The M10 is powered by a 1.6GHz octa-core Exynos 7870 chipset which is based on a 14nm process and offers eight ARM Cortex-A53 cores clocked at 1.6GHz. The M20 gets the newly announced Exynos 7904 chipset which is also based on a 14nm process. The chipset is equipped with two Cortex-A73 cores that run at 1.8GHz, and six Cortex-A53 cores that run at 1.6GHz.

When it comes to the processor and memory, it’s pretty evident that the Galaxy M20 is the one to go for if you are looking to play a lot of games or multitask on a smartphone. The 4GB variant of the M20 will handle this better than the Galaxy M10. The M10 is for light phone users who aren’t looking to stress the device, but want a good-looking phone with a waterdrop display.

– Both the Galaxy M10 and M20 ship with Android 8.1 Oreo with a new Experience UI 9.5, which offers a cleaner, smoother UI. Samsung inadvertently revealed that the two phones will receive Android Pie later this year in August.
