How many kg cement and how many kg sand do you need in 1 cubic meter of mortar rubble? More details, thank you!

How many kg cement and how many kg sand do you need in 1 cubic meter of mortar rubble? More details, thank you!

After consulting the consumption quota and other data:
The content of pure & nbsp; 1 cubic M 10 cement mortar is 325 × 0.271t cement, 1.015m3 yellow sand and 0.29m3 water
One cubic meter of m10cement mortar rubble: 0.0249t 325 cement and 0.09338m3 yellow sand;
That is to say, the content of cement mortar is 0.092m3 per cubic mortar rubble
The same is true for input measurement

How much sodium hydroxide and water are needed to prepare 500 ml 10% sodium hydroxide solution (density is 1.1 g / cm3)?

To prepare 500ml (500cm3) sodium hydroxide solution with 10% mass fraction, the mass of sodium hydroxide is 500cm3 × 1.1g/cm3 × 10% = 55g; the mass of water is 500cm3 × 1.1g/cm3-55g = 495G. A: the mass of sodium hydroxide and water are 55g and 495G respectively

How many liters of diesel is one kilogram of LNG equivalent to

1.2-1.3L

How to convert units of LNG, gasoline and diesel?

From the perspective of calorific value: 1L (diesel) ≈ 1.1 (natural gas); 1.33l (diesel) ≈ 1.47 (natural gas); 1kg (LNG) ≈ 1.47 (natural gas); 1.33l (diesel) ≈ 1kg (LNG) 1L (gasoline) ≈ 0.9 (natural gas); 1.63l (gasoline) ≈ 1.47 (natural gas); 1.63l (gasoline) ≈ 1kg (LNG)

How many cubic meters of natural gas is one liter of diesel

The calorific value of diesel is 34.05mj/l and that of natural gas is 36.22mj/m3,
1L diesel = 34.05 / 36.22 = 0.94m3 natural gas

Conversion of standard coal, compressed natural gas (CNG) and liquefied natural gas (LNG)
What is the conversion relationship between standard coal and CNG? It refers to the kilogram of standard coal converted from a cubic meter of CNG? (it is CNG, not natural gas under normal conditions)
There are also commonly used CNG vehicles. How many times is the CNG density under normal conditions? (20MPa pressure)
How to convert standard coal

Conversion to standard coal is based on the heat equivalent conversion, you can query the relevant data for conversion, such as the calorific value of a ton of coal and the calorific value of 1 standard cubic meter of natural gas
The results show that the temperature is 20 ° 1m and CNG (20MPa) = 200m and the density of standard square natural gas is 200 times that of normal gas
The temperature is 20 ° 1m & # 179; LNG (101kpa) ≈ 1400 standard cubic meters, LNG is liquid, and there is no density contrast between gas and LNG

Comparison of CNG and LNG

There is a big difference between these two kinds of natural gas. The storage and distribution of LNG is large. Taking the LNG of Guanghui in Xinjiang as an example, the calorific value is relatively high, which is more than 10% higher than the general CNG and pipeline ng. The transportation distance is long. Taking Shandong as an example, the transportation distance is about 3300 km, and the production cost and transportation cost are higher than the price of CNG

The difference between LNG and CNG

Both of them are natural gas with the same components, but they exist in different states
CNG (compressed natural gas) is a kind of compressed natural gas (more than 3600 psi) which is stored in a container in gaseous state
LNG (liquefied natural gas) is the abbreviation of liquefied natural gas. LNG is condensed into liquid by cooling the gaseous natural gas to - 162 ℃ under normal pressure. Natural gas liquefaction can greatly save storage and transportation space and cost, and has the characteristics of high calorific value and high performance

What kind of gas is the natural gas for vehicles, LNG or CNG

Small vehicles mainly use CNG, with short driving mileage, low gas consumption and low cost of CNG gas tank; large vehicles mainly use LNG, with long driving distance, large gas consumption and high cost of LNG gas tank
At present, CNG is used in household cars and taxis, while LNG is widely used in heavy trucks, buses and city buses

What is the difference between liquefied natural gas and gasification

Liquefied petroleum gas is the abbreviation of liquefied petroleum gas (LPG), which mainly comes from the by-products of petrochemical industry; natural gas is CNG, which mainly comes from the exploitation of gas fields, and some of it is synthesized by chemical industry, but the cost is high
Both LPG and CNG can be used as fuel. The unit calorific value of CNG is higher than that of LPG. The unit weight of LPG is higher than that of CNG. LPG is heavier than air, and CNG is lighter than air. The cost of CNG is lower than LPG, but the safety of CNG is lower than that of LPG
Liquefied gas station needs gasification device in residential area, but gasification mode is directly related to gas supply scale of residential area
Natural gas is usually transported by pipeline. The pressure on the main line of the pipeline is very high, so it can't enter the house directly. It can only be used by end users after the pressure is reduced to the standard of entering the house step by step through the natural gas pressure regulating station
Condensate is inevitable in the process of natural gas exploitation and compression transportation. Condensate tank is used to remove the condensate
