how to make cement?

Answer 1

Buy a bag of Sackreat from the store and mixit up, Easy!

Answer 2

tedrp1962 answer was the best, if it is available. The term you want is actually "concrete," not "cement." The reason that is important is that if you ask for the wrong thing, they might not tell you it is not what you want.

BTW, Sackrete is a brand name of a mixture of cement, sand, and possibly rock. It is mixed at the correct proportions for usage, right out of the bag, no guess work. There are other brands that are probably all of equal quality.

There are also different mixtures, depending on what you are going to do with it. There are also additives available, again, depending on what you are going to do with it.

Answer 3

there is this substance that's called the cement powder. however u don't just use that solely. u need sand and water as well. measure 1 unit of cement powder and 4 units of sand. add water and stir them well until a desired texture depending on the use of the cement is attained.
my source? i went to cambodia a few years back for youth volunteer work and our project was to build a drainage system for one of the orphanage there. this was how we made cement thou u'll most likely think it's not professional at all.

Answer 4

In the most general sense of the word, cement is a binder, a substance which sets and hardens independently, and can bind other materials together. The name "cement" goes back to the Romans who used the term "opus caementitium" to describe masonry which resembled concrete and was made from crushed rock with burnt lime as binder. The volcanic ash and pulverized brick additives which were added to the burnt lime to obtain a hydraulic binder were later referred to as cementum, cimentum, cäment and cement. Cements used in construction are characterized as hydraulic or non-hydraulic.

The most important use of cement is the production of mortar and concrete - the bonding of natural or artificial aggregates to form a strong building material which is durable in the face of normal environmental effects.

Hydraulic cements are materials which set and harden after combining with water, as a result of chemical reactions with the mixing water and, after hardening, retain strength and stability even under water. The key requirement for this is that the hydrates formed on immediate reaction with water are essentially insoluble in water. Most construction cements today are hydraulic, and most of these are based upon 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.

Answer 5
