Cinder Block Strength? emergency!

  • We are currently upgrading MFK. thanks! -neo
How many Gallons is that tank Bderick? THat looks like a good stand solution for my 55G and yours doesn't even look ugly!
 
Hey coolguy, Just a thought but I think it will increase earthquake survivability if you stack your bricks where they are interlocking and make it solid bricks under the whole stand, not just the outside edges. Bonding them together with liquid nails will add to the strength also but would make it difficult to move in the future. These things are all relative to how large the earthquake is your trying to survive. Example: If a hole opens in the earth and swallows your building it does not matter if your tank is intack. If its just a little 4 to 5.0 quake your probably O.K. I live right on top the san andreas fault and have never had issues with home buildt 2x4 framed stands. I'll build you one and trade you for your Vieja Synspillum. You gotta pick it up though cuz I dont have a truck.

I've got my 180g sitting on blocks and wood planks. They are not gonna hold up in a earthquake because they are not anchored together. As far as damaging a block and seeing total stand failure, I would douhgt there is anything is your house that could cause this, except maybe a 15# sledge hammer. Of course I would think most stands would fail if they went up against a sledge hammer.

Best bet is to overlap the blocks with one another, not just stack individual towers. I'll try to find a pic of my set up.

You obviously don't have either small kids or 200 pound wolves charging around the house. Other than that the edge of a two wheel dolly can easilly crack a cement block because I've seen it done...

It is a 180g tank, below is a pic of the quick stand I threw together for a 55g. This stand does not sway back and forth and is very solid.

Nope just teenagers, you must be buying cheap block wolf. Remember these are the same block that most schools are made of. I myself work in constuction and have had to run electrical conduit through hollow block walls many times, it takes 4-6 good wacks with a claw hammer to create a hole in one of these blocks, this is real world though. Not in the world where puppy dogs, small children or monster dollys can destroy concrete block.:screwy:

lol, yeah, 4.0-5.0 here in socal isn't much. not really even worth getting out of bed for.
 
Someone mentioned using a styrofoam sheet between the aquarium and stand/wood. This is recommended by manufacturers to even out any weight descrepencies from not having a totally an evenly straight stand. Seems to me if you put the blocks right next to each other touching each other the re-inforcment may be much better for earthquakes????????????

I don't mean to get technical (well maybe), but I don't believe cinder blocks are made anymore. Blocks are now made made from cast concrete (portland cement and aggregate, usually sand and fine gravel). Cinder blocks were made from coal cinders and portland cement and are very dark in color. I know a lot of people still refer to them as "cinder" blocks, but I just thought I would add my 2 cents of construction background to clarify this point.
No offence intended...:)

I did some work in a block plant. Most are made with portland+ sharp sand+ stone dust (screenings) + plastisizer.
No offence intended:grinno:
