Q:Ive just got cement in my fishpond- when can I put the fish in?
Cement contains large amounts of calcium and magnesium, which act as alkaline buffers when dissolved into water, like a pond. Because of this, you're likely to see your pH skyrocket for quite some time. If there's any way you can get the cement out of the water, that would be best. If not, you're gonna be dealing with an abnormally high pH for some time, which isn't necessarily a bad thing, as Goldfish and Koi will do just fine under such conditions. Regardless, I'd try to flush out as much of the water as possible before getting any fish.
Q:which does not form a part of reinforced cement concrete?
Lime and silica make about 85% of the mass of cement. However, lime by itself is not used in the production of Portland cement concrete mixtures. Hydrated lime is usually used in the production of asphaltic concrete mixtures. See the links below for more information.
Q:Should Durarock be cemented to the subfloor and 11/2" roofing nails used instead of screws to set?
I've never heard of cementing the durarock down (does he mean mortar or construction adhesive?) but I'm sure it wouldn't hurt. Under no circumstances would I recommend using roofing nails to fasten down concrete board. Nails pull out screws do not and rigidity is key to durarock being successful. I would tell him to glue it down if he wants but nails are not acceptable. He is just looking for a way to cut corners and save time.
Q:stucco over painted cement?
it wont stick. i havent done much stucco though, just some repairs.
Q:How do I build a fish pond using cement?
it doesn't sound like you've given this enough thought, if not done correctly the first time you can REALLY end up with a problem please go to pet shop or garden shop or library and get books on garden ponds, they will tell you everything you need to know it's too involved to go into on this forum
Q:I need a list of cement, concrete and aggregates Public companies the most important ones or largest Co.!
here are some of the largest: cemex holcim ltd lararge florida rock there are many others, go to yahoo finance, they will list may others. Hope this helps.
Q:james hardie cement siding ?
James Hardie company makes many cement board products for the building industry, including Hardi-Plank for siding, Hardi-backer to put behind tile or stone in damp areas, etc. Their products are all excellent quality, and are worth the cost -- I use them extensively. Cement board is heavy and somewhat brittle -- buy it locally from a quality vendor (Lowes, etc) and don't worry about the few cents difference between what you heard and what you see. You're getting excellent value, and freedom from unnecessary maintenance. Rejoice.
Q:Cement on teeth from braces?
Both. I had braces years ago and it gets to a point where you don't even notice them anymore. If the problem continues just go back to the orthodontist and they should fix it.
Q:Expanding cement wall crack repair help?

Q:The Now building materials business to do it, including what aspects?
To see what side, if it is a real estate developed areas, it is very good to do
We are one of the largest concrete admixture-products manufacture in China. We can produce different kinds of high quality conveyor belt and transmission belt.
