To calculate the weight: Height x Width x Length x 2.5
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
about 1/6 of that on land
Divide the weight by the volume.
by using calculator
weight=mass*gravity
Calculate the cross-sectional area of the barrier in square feet, multiply the area by the density of concrete (150 pounds per cubic foot), and multiply the answer by the length of the barrier in feet.
Precast concrete is a construction element made of that material and finished before its installation in the building frame. The mix of concrete must be cast or scaffolded until it gets enough strengh to handle and support own weight.
to answer your question, one must know the thickness of the slab? then only the weight can be calculated
You need to calculate the total volume of the space that the concrete has to fill. if you're doing a slab 4" thick a cu. yd. will cover 81 sq. ft. Take the total area and divide by 81 to get the number of yard needed.
weight of hardened concrete + 100 kgf/m3
the lightweight concrete weights are depends upon their aggregates.... basically the weight of lightweight concrete is 50lb/cubic feet
Weight of concrete is 155 lbs/cft or 70.308 kg/cum
weight and length of steel bar ~6
unit weight= weight/volume.unit weight of normal concrete = 24 MPaIt is also known as density of concrete
The weight of a concrete mixer truck can vary depending on the size of the truck and if the truck is weighted with concrete it may be carrying. A concrete mixer truck is about 20,000 to 30,000 pounds without concrete.

Yes- because they are not a solid block of concrete- they are hollow with a large air space. The weight of the water displaced is greater than the weight of the hollow concrete hull, and it will float.
