Apr 24 2017The unit weight otherwise known as the specific weight is the total weight of a substance in a single unit of volume Although it is similar to specific gravity or density it is not the same because weight is dependent on gravitational acceleration The specific weight of an object on Mars is not the same as it would be on Earth

Mar 19 2016In my lectures and notes my professor keeps writing out density as lbs/ft 3 and unit weight as lbs/ft 3 For a material such as concrete it could have a density of 167 lbs/ft 3 but a unit weight of 103 lbs/ft 3 I am confused as to how these two values are different even though they have the exact same units

Re Weight of 1 liter wet sand I was curious about what a 2 liter bottle full of wet sand would weigh was just looking to see if i did math correctly If wet sand being 3500 lb/yr3 3500/27sf (27 sf3 per cubic yard) = 129 258 lb/ft3 So 1 liter being 61 02 in3 Using the same one for gallons just subing liter for gallon

If the volume is unit then Bulk Density= Mass Unit in kg/m 3 or lb/ft 3 In this definition the volume is that contain both the aggregates and the voids between aggregates particles The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3

At U-Sand we've developed reliable easy-to-use random orbital floor sanders any homeowner or "do-it-yourself-er" can master Don't be intimidated by aggressive drum sanders that can be difficult to operate and damage your floors quickly Maneuvering a U-Sand floor sander is as easy as taking a stroll

taken in terms of weight basis this may average approximately at 1 7 (cement aggregate) However there have been instances of employing a lean mix of as high as 1 9 by manufacturers where hollow blocks are compacted by power operated vibrating machines The water cement ratio of 0 62 by weight basis can be used for concrete hollow blocks

density and unit weight of soils using a sand cone apparatus 1 2 This test method is applicable for soils without appre-ciable amounts of rock or coarse materials in excess of 11⁄2 in (38 mm) in diameter 1 3 This test method may also be used for the determination of the in-place density and unit weight of undisturbed orin situ

What Is the Weight of Gravel Per Cubic Yard? The weight of gravel per cubic yard is approximately 2 970 pounds or 1 48 tons if the gravel is dry If the gravel is out of water the weight per cubic yard is approximately 1 620 pounds or 81 tons

Volume of grout If you're using portland cement 1 cubic foot loose volume weights 94 pounds and has a specific gravity of 3 15 Dividing the weight 94 pounds by the specific gravity times the unit weight of water (62 4 pounds per cubic foot) gives a volume of cement

Sand Estimation Calculator is an online tool to estimate how much sand is required from the given building measurements of width length and height In the field of civil construction it is very much required to estimate how much sand is required to complete the building

When it comes to block making the State of Michigan is abundant with normal weight aggregates of sand gravel and limestone (ASTM C-33) throughout the state which when utilized in the concrete block manufacturing process will result in concrete masonry units (CMU's) that ASTM classifies as normal weight (density of 125 lbs/cf and above)

As specific gravity is just a comparison it can be applied across any units The density of pure water is also 62 4 lbs/cu ft (pounds per cubic foot) and if we know that a sample of ammonium nitrate has a sg of 0 73 then we can calculate that its density is 0 73 x 62 4 = 45 552 lbs/cu ft

After mixing the unit weight is measured to be 145 7 lb/cu ft The yield is determined as follows yield = total weight / unit weight = 3956 lb = 27 15 cu ft 145 7 lb/cu ft When working with inch-pound units the design yield is always 27 cubic feet Relative yield is the ratio of yield to the design yield
