If it is less dense than water, then the specific gravity is less than 1. Specif gravity of sand is 2.6 - 2.7 and that of cement is 3.14 - 3.15 ,i.e. for the same volume occupied by cement and sand , cement is “3.15/2.8 = 1.16 times”heavier than sand.

You can make dry or cured cement heavier by adding metal powders or whiskers to it. Stainless steel whiskers or needles are sometimes used to improve the flexural strength of cement slabs. Whiskers also reduce the modulus of elasticity and crack propagation. Thank you for your excellent question.
A cubic yard of sand weighs 2,400 lbs. A ton of sand is approx. 4/5 of a cubic yard.
... of its high degree of aggregation (i.e., small total porosity), concrete has, in general, a higher dry density than soil. Typical values of dry density in different types of soils and in concrete are shown in Table 2.1.
Point out that as long as the volumes are equal, sand is a material that is heavy for its size compared with water. For samples of any size - as long as the size of the samples is the same, sand will weigh more than water.
The average weight of a cubic yard of concrete is typically around 3,900 lbs when wet and about 3,500 lbs when dry. However, moisture content and mix proportions—the ratios of water, cement, and aggregates—can alter this figure.
Sand comes in varying coarseness which may mean slight differences in actual weight but basically a cup of sand weighs about 12.45 oz and there are 16 cups (199.2 oz) in 1 gal so 5 gal is 996 oz. There are 16 oz to a pound so divide 996 by 16. Therefore 5 gal of sand would weigh 62.25 lbs.
1 cubic yard is roughly 1.5 tons of sand and will give you just over 3 inches on 100 square feet.
How much does a yard of concrete weigh? A solid, unbroken slab of concrete weighs about two tons (or 4,000 pounds) per cubic yard. Breaking up concrete roughly halves the total weight per cubic yard to about one half ton (or about 2,000 pounds).
The ideal concrete mixing ratio for any concrete is 4:2:1, where 4 parts are crushed stones, 2 parts are sand, and 1 part is cement. Note: The ratios differ according to the applications.
Does adding rock to concrete make it stronger? Simple answer: No. If you add rocks, which usually means stones larger than 9 cm, you get a weaker concrete. Concrete with large rocks added is called cyclopean concrete.
C40 as the strongest standard mix for heavy-duty applications. When you're looking for the strongest standard concrete mix for heavy-duty applications, C40 is your go-to choice. For this mix, you'd typically use a proportion of 1 part cement, 1.5 parts sand, and 3 parts gravel, with a water-cement ratio of about 0.35.
Concrete mix has gravel in it, which makes it stronger and more durable. Sand mix is used mainly for patching or where you want a particularly smooth finish. Check your state and local codes before starting any project.

You can use materials like sand, gravel, rocks, dirt, steel plates, cement, or concrete as filler depending on how much weight you need.
A: Concrete weighs about 2.4 times as much as water for a given volume.
Cost of Sand
Bulk sand prices range from $10 to $40 per ton, or between $15 and $50 per cubic yard depending on the type, quantity, and distance delivered. The average cost of sand installed is $50 to $150 per ton, which includes the sand, delivery, spreading labor, supplies, and equipment fees.
A regular size pick-up truck will hold three cubic yards of mulch. Topsoil, compost and heavier materials limit a load to one cubic yard.
wheelbarrow you would be looking at 14 wheelbarrows of material per yard. A 3 Cubic Ft. wheelbarrow will take approximately 9 loads to equal 1 yard of material. Use the fields below to quickly figure how many wheelbarrow loads your project will take.
Here is how much sand these item will hold: 5 gallon bucket = 70 pounds of dry clean play sand (80 to 90 lbs if wet sand)
A good rule of thumb for most concrete mixtures is 150 pounds per cubic foot. If you fill a 5-gallon bucket you've moved nearly 100 pounds of concrete. Fill a standard contractor-size wheelbarrow and you could be pushing more than 800 pounds. But there also are both lighter and heavier varieties.
The average cost of concrete per yard is about $130, with a range of $110 to $150 per cubic yard. For most large concrete projects, you'll need to order concrete by the cubic yard.
In short, the difference between cement vs concrete is easy to clear once we know all the basics of their compositions. Cement is a binding agent made from limestone and clay; whereas concrete is a building material created through the proper mixing of cement, water, sand, and rock.
Employing BubbleDeck Technology
BubbleDeck technology involves embedding hollow plastic spheres within the concrete. These spheres occupy low-stress areas, reducing the overall weight of the concrete while maintaining its structural integrity.
