Q:South Building Materials Sandstone Cement, mostly transported by the canal from the north. Real estate downturn, will have an impact on the shipping of building materials?
There is little water and water costs, but the guess will not cross to 500km, because the second three times or even four times the cost of transport and storage costs are not small Real estate downturn can be shipped to other The worst result is the overall price drop of 20%, the business will not have to do Well, the way to ask the water fee under the seriousness of the call is what?
Q:what is the best kind of cement for filling cracks in foundations?
Filling cracks with cement is futile. If you are filling a form tie hole then hydraulic cement is the choice. For cracks, use an epoxy filler.
Q:Rubber cement glue or liquid elmers?
Rubber okorder.com, a great site that has you select the two materials you plan to glue and offers glue advice. Best of luck.
Q:matching color of cement on driveway?
Unfortunately that will be very difficult. As Concrete ages mother nature changes its appearance, you will never be able to get new concrete or even a small patch job to match up to the old.
Q:What is Ferro cement concrete?
Ferrocement is a composite material which is used in building or sculpture with cement, sand, water and wire or mesh material—often called a thin shell in North America. Ferrocement has great strength and economy. It is fireproof, earthquake safe and does not rust, rot or blow down in storms. It has a broad range of applications which include home building, creating sculptures, repair of existing artifacts and building boats and ships.
Q:Can you carve a dried block of cement?
Yes its possible but it requires you too much time to finish that.
Q:coal fly ash % used in cement?
Portland Flyash Cement contains up to 30% fly ash. The flyash is pozzolanic, so that ultimate strength is maintained. Because flyash addition allows a lower concrete water content, early strength can also be maintained. Where good quality cheap flyash is available, this can be an economic alternative to ordinary Portland cement.
Q:Is Portland cement considered to be hydraulic? (cement that cures underwater)
Most construction cements today are hydraulic, and most of these are based on Portland cement, which is made primarily from limestone, certain clay minerals, and gypsum in a high temperature process that drives off carbon dioxide and chemically combines the primary ingredients into new compounds. Non-hydraulic cements include such materials as (non-hydraulic) lime and gypsum plasters, which must be kept dry in order to gain strength, and oxychloride cements, which have liquid components. Lime mortars, for example, set only by drying out, and gain strength only very slowly by absorption of carbon dioxide from the atmosphere to re-form calcium carbonate through carbonatation.
Q:Hi, I am having an extension put on the side of my house and bought some cement last year, however it is hard?
BOB has it in one. It has gone-off with the natural moisture in the air, a builder would not even consider using it, as it is now useless.
Q:Is jypee cement best for house?
in my opinion jypee cement is best for house because among of the other cement are not good but jypee cement is good.
