what is the weight of a 2x2 concrete slab?

The weight of a standard concrete paving slab is about 45 kg.

So you can only take 2 in your trailer, unless you somehow increase the limit to 135kg, in which case you could take 3.

Calculation:

Standard slabs are 2 inches thick.

The volume of one slab is:

(24*24*2)*(0.0254*0.0254*0.0254)m^3 = 0.0188779 m^3

The density of concrete is 2400 kg/m^3, so the mass of one slab is ~45kg.

RE:

i am trying to work out how many 2x2 slabs i can carry in my trailer as i am limited to 122kg

You state no units for 2x2 although I guess its 2 foot square. How thick are they ?.

Try this:

(1) Assess the volume of one in metres cubed

(2) Multiply the Volume from (1) by 2400 [ thats the desity of concrete in Kg / m3 ] giving the mass in Kg

(3) Divide 122Kg by the answer in (2) to give the number of slabs

The paving slabs weigh about 45.5kg each so at 122 kg you are limited to 3. Sounds like a small trailer to me.

if it is a normal 2 ft x 2ft slab i estimate 25 kg for a 2 inch thick slab which would mean 5 in your trailer which doesn't seem alot, just load it til you think and take it steady.

approx 100 lbs , its hard to say without knowing the density of the concrete used

For the best answers, search on this site https://shorturl.im/ax7nh

thats roughly 16 x 16 x2 in. so about 22 lbs.

Concrete, Asphalt 140 pounds/cubic foot

Concrete, Gravel 150 pounds/cubic foot

Concrete, Limestone w/Portland 148 pounds/cubic foot

Cement, Portland 94 pounds/cubic foot

Cement, mortar 135 pounds/cubic foot

Cement, slurry 90 pounds/cubic foot

Can you specify?
