can we use polypropline fibre in concrete
The answer is, it depends. Different types of bituminous cement concrete (asphalt hot mix) use different percentages of asphalt cement. In Virginia, base mixes use at least 4.4% asphalt, while surface mixes are up to about 6%. Liquid asphalt is a little heavier than water; it weighs about 9.4#/gallon (depending on the source and grade). Here's the math: Base mix 2000#/ton x 4.4%/9.4#/gal. = 9.36 gal/ton surface mix 2000#/ton x 6%/9.4#/gal. = 12.76 gal/ton hope this answers the question.
The base unit of voltage is the volt, a combined unit meaning joules per coulomb.AnswerThe SI unit for voltage is the volt (symbol: V), which is a derived unit -not a base unit. There are seven base units in the SI system: metre, kilogram, second, ampere, candela, kelvin, and mole. SI units which are not base units are termed 'derived units'.
The unit weight of 16 mm reinforcement is 1.58 kg/m
The unit weight of PCC is 24KN/cum and that of RCC is 25KN/cum
The unit weight of asphalt concrete typically ranges from 145 to 155 pounds per cubic foot (pcf) or 2,300 to 2,500 kilograms per cubic meter (kg/m3). This value can vary depending on the specific asphalt mix design and aggregate used in the asphalt concrete.
weight. There are 1000 grams in a kilogram, the base unit used in science to quantify weight. In physics, it is classed as a unit of mass, not weight.
The base unit for weight measure in the metric system is "g" or grams.AnswerThere is no Base Unit for weight in the SI system. Weight is measured in newtons, which is a Derived Unit, not a Base Unit.
The base unit for mass is the kilogram. The base unit for temperature is kelvin. The base unit for volume is the metre cubed, m3. The base unit for length is the metre. Weight in a scientific sense is the force exerted on a body by gravity, force is measured in newtons, is everyday use weight is the same as mass, so people talk of weighing things in kilograms.
The value of compaction for an asphalt base course is typically targeted at 95-98% compaction density. This level of compaction ensures that the base course is strong, durable, and able to support the weight of the overlaying asphalt layers and traffic loads. Achieving the specified compaction value is critical for the long-term performance of the pavement structure.
grams Correction: The gram is a unit of mass, not weight. The kilogram, not the gram, is the base unit of mass. The SI unit for weight is the newton, but it's a derived unit calculated using mass and gravitational pull.
Wet asphalt weighs about 145 pounds per cu. foot.
I think that you mean Metric unit. The base unit is the Gram. Prefixes are used to modify the unit. For instance, Kilogram, meaning 1000 Grams.
Note that weight actually refers to force exerted due to the acceleration of gravity and the mass of an object. It is commonplace to see the terms weight and mass used interchangeably, though. The SI base unit of mass is the kilogram. The original metric system specified the gram as the base mass unit. The SI base unit of force, which technically would be the correct unit of weight is the Newton (kg*m/s2). The dyne is another 'metric' unit of force (g*cm/s2).
The SI unit of weight is the newton (N), which is a Derived Unit.
kilo grams is the si unit for weight massThis answer is incorrect.A kilogram is the SI base unit for mass, not weight. Weight is a force, and is measured in newtons.
Not sure there is a definitive answer, or that there is a 'metric' system, but the S.I. unit of weight is the Kilogram (N.B. not the gram).
