For a standard concrete mix, you typically use a ratio of 1 part Portland cement to 2 parts sand and 3 parts gravel. Therefore, for a 94 lb bag of Portland cement, you would generally add about 188 lbs of sand and 282 lbs of gravel. This can vary depending on the specific application and desired concrete strength, so it's always best to consult a concrete mix design guide for precise ratios.
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.

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.
The strongest cement is typically made using fine, clean, and well-graded sand, such as river sand or manufactured sand, which ensures optimal particle distribution and minimal voids. The sand should be free of impurities like clay, silt, and organic matter, as these can weaken the bond between the cement and aggregates. Additionally, using a proper mix ratio and high-quality Portland cement can further enhance the strength of the final product.

According to the Portland Cement Association, portland cement should not be capitalized.

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.

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.

To make concrete from scratch, mix cement, sand, and gravel in specific proportions with water. The mixture should be thoroughly combined and poured into molds to set and harden.

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.
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.

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.
