The Moon's average density is about the same as the density of which of the Earth's layers?
The Moon's average density is about the same as the density of the Earth's mantle.
If an object sinks when being placed in water its density is?
To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
What is the mass of a sample divided by its volume?
The quantity you are describing is density, which is the mass of a substance per unit volume. Mathematically, density (D) is represented as mass (m) divided by volume (V), so D = m/V.
The amount of mass an object has per its volume is known as .?
Density = Mass/Volume
What is the percent of flyash in ppc cement?
the percentage varies from 15% to 35%.
What is the ratio for fly ash as the cement replacement in concrete?
Replacement of cement with flyash in concrete is 20-35 % by weight for normal structures. however for special structures like dams the replacement levelscan be increased to up to 70 %. (where flyash must be ISI standards compatible or any such standards) This replacement also reduces water requirement by 2.5 % for every 10 % replacement of flyash used.
Flyash utilization in thermal power plants?
Both flyash and bottom ash are waste created at coal fired power pants. Bottom ash has a larger particle size. The two materials can be used as fill, building mounds (for overpasses on highways), as an aggregate in concrete and in the mix for paving materials.
Flyash bricks class 10 mix properties?
Fly ash bricks class 10 mix properties makes is heterogeneous.
Can fly ash be used in reinforced concrete and prestressed concrete?
There are experimental results showing that the flyash can be used up to 30 % as a cement replacement material. Some up to 80 % flyash has certain properties and it can be used some percent to the concrete mix as a admixture.. Proper trial mix and test shall be carried out for required strength and durability..
What is the function of flyash in cement?
Functions of fly ash in cement,It is used as a replacement material.Low heat of hydrationGains strength more than that of the ordinary cement.
What are the ingredients for concrete solid block?
Concrete block is made from Portland Cement, water, sand and aggregate. The aggregate may be in the form of flyash or cinder from burnt coal.
What is flyash?
Fly ash is one of the residues generated in combustion, and comprises the fine particles that rise with the flue gases. In an industrial context, fly ash usually refers to ash produced during combustion of coal.
How do you dispose of lignite waste?
they are many purpose used to lignite waste because it has flyash powder so any chemical company or fertlizer company its used mixxing to that powder and creating new material helpful of lignite waste
What is the formulae for Flyash?
The formula for fly ash is primarily silicon dioxide (SiO2), aluminum oxide (Al2O3), and iron oxide (Fe2O3), along with various other minor constituents. Its composition can vary depending on the source material and combustion conditions.
What is the difference density and relative density?
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
What kind of work environment does a welder have?
If working in papermills and power houses it's very noisy and dirty work. Extreme heat and during winter you have to try and keep yourself warm. Be around black liquor and flyash. Sometimes working in confined spaces
