Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
What type of portland cement concrete should be used when the repair can be protected from traffic for 24 hours?
type 1
Fine grained material used in cement?
The fineness of cement has an important bearing on the rate of hydration and hence onthe rate of gain of strength and also on the rate of evolution of heat. Finer cement offers agreater surface area for hydration and hence faster the development of strength.
How thick should gravel be to pour concrete on top?
should be at lest 4 inches
Why should masonry cement never be used for concrete?
penis
Should Portland cement be capitalized?

Must plaster be kept wet?
Plaster contains portland cement. Portland cement technically doesn't "dry", it "cures", meaning that a chemical process causes it to harden. After the portland cement starts to "set up", it should be kept damp so that it doesn't crack or otherwise become damaged. When it's still fresh, you don't want to spray a lot of water on it, that could wash away some of the portland cement. Instead, just mist it to keep it from drying.

Is there a special type of cement to repair cracking areas around a pool?
There are two types of Portland cement you could use. (white and grey) The color you use is determined by the area you are repairing.If you are repairing the interior finish you should use Portland white cement.(if it is a colored finish you will need to add dye) If you are repairing concrete,shotcrete or gunite you should use Portland grey cement.Keep in mind these cements will cosmetically repair cracks but will not structurally repair them.
Which type of concrete should you use when it must reach its design strength in about 28 days?
concrete made upof ordinary portland cement gain strength in 28days

Can appaloosas be put on gravel?
I'm not quite sure what you are asking, but if you are asking if you can ride them in gravel yes. If you plan to ride more than once a week on gravel you should get your horse shoed. If your saying eating gravel no you can. Putting their pen on gravel is ok but you should have a dirt part too.
Should limestone be used as gravel?
No
How long can you store cement without using it?
Portland cement can be stored indefinitely provided it is not exposed to moisture. Most cement bags have a thin plastic lining to protect it from humidity, not rain, and is only meant to be temporary. Therefore, you should plan to use the cement product from an unopened, weather protected bag in weeks, not months. When the bag is overexposed it will result in "dead" cement, because it has already begun the chemical reaction with water, and reveals itself by hardening and clumping. Throw that bag away, it's dead.
Mixture combination of 1 cubic meter concrete?
The mixture depends on the concrete strength, flow properties and other specifications required, quality of cement, aggregates and other chemical additives that will be used. Typically 1 cubic meter concrete should include about 310kg cement, 800kg sand, 900kg gravel and 220kg water.
How many bags of pre-mix cement is needed to mix 1 cubic yds?
Cement comes in bags that weigh 94 lbs. The volume of the bag is approximately 1 cubic foot. If you want to mix concrete which is a mixture of a coarse aggregate (gravel) and a fine aggregate (sand) and something to bond the two aggregates together (cement) then firstly you need to know the strength concrete that you require. For 1 cubic yard of 3000psi (pounds per square inch) strength you will need about 6 bags cement 12 cubic feet of sand and 24 cubic feet of gravel. Rule of thumb is the ratio should be 1:2:4 (cement:sand:gravel)
