PORTLAND CEMENT
Portland cement is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most non-specialty grout.
It is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the clinker, and adding small amounts of other materials.
Several types of Portland cement are available with the most common being called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available.

- Q:how is cement prepaed? what are the uses and different types of cement?
- I've been in exactly the same situation. We live on the edge of nowhere and can't get delivered concrete. We poured our greenhouse floor, using Portland premix cement and a mixer. Our mixer is slightly smaller than yours. We used extra water in the mix so it would stay workable longer. Bad idea! The floor did fine until the first winter. It then split, chipped cracked and, well, you get the picture. We ended up redoing it. The second time we divided the floor into three sections. Each section had its own small 3/8 rebar web placed 2 above ground in a 4 floor. We supported the web by driving 10 pieces of 3/8 rebar into the ground and wire to hold the web to them. Lastly, on the sides where the adjoining sections would go, we used 1 x 6 pieces of redwood. We drilled them and ran rebar through to the web – leaving 2' sticking out for attaching the new sections. That piece sticking out was attached to the next section's rebar web. It has been there for several years now, and has no cracks at all. Our temperatures range from 105°F in summer to -40°F in winter. I put a link in to show how to determine how many cubic yards of concrete you'll need. Good luck!
- Q:What is the total weight of a cubic meter of the mix? what part is cement? stone?sand? add these fractional amounts.what is the result? 420+150+120=690Kg, total 690 -420 used what part =n 420/690divided by 10/10=42/69divided by3/3=14/23 cement, how do you figure out stone and sand?
- Cement = 420/690 =14/23 Stone = 150/690 = 5/23 Sand = 120/690 = 4/23
- Q:So am trying to remodel my bathroom and was wondering if cement board would work better than greenboard as the shower wall? I've read that cement board can be used on floors or kitchen tops but am not sure if I can use it on bathrooms??
- Greenboard by all means. It was designed to be used around tubs
- Q:can rubber cement be used for the same uses?
- Vinyl Cement Uses
- Q:I don't know whether to use concrete or cement. It is for a waterfall so it will be constantly subject to moving water, which do you think will be best concrete or cement I'm not sure how long it will last with the winter years and freeze-thaw etc...So basically is cement waterproof enough and will last after constant water going on it?
- cement is the chemical in concrete above is some stuff to read about it they have been using concrete for centuries for fountains
- Q:what is sound proof cement made out of?
- I don't think it exists. Cement is typically used as a binding agent for concrete. Because it is very dense, it transmits sound vibrations thru it, and would not be sound proof. There are sound attenuating walls made of concrete, but they still allow some sound to pass thru. The only sound-proof place is inside an anechoic chamber!!!
- Q:Describe and Differentiate Portland Cement and Pozzolonic Cement?
- The common variety of cement is known as normal setting or ordinary cement.It was called Portland cement because it had resemblance in its colour after setting, to a variety of sandstone which was found in abundance in Portland of England.Pozzuolana is a volcanic powder which can also be processed from shales and certain clays.The % of this in cement is 10 to 30.This cement is used in marine structures ,sewage works and foundation under water.
- Q:Whats the difference between masonry cement and mortar? If you mix portland cement with sand does it become masonry cement or mortar?
- so far as I know, the only difference is the masonry cement is still dry, once it's mixed up, then it's mortar. You use finer sand than with other concrete mixes.
- Q:I have a floor area of 4meter x 2meter to lay tiles. How do I calculate how many bags of 50kg cement do I need?
- You don't need cement at all. Ceramic tile is installed using thinset mortar. There are several types depending on the particular type of tile and the substrate you will cover. Additives are recommended for certain situations. The tile manufacturer should have a recommendation for mortar type and additives, if needed. Mortar coverage is given as a range, and each manufacturer will state that range on the bag. A typical sanded mortar will cover 0.3 to 0.4 square meters per kilogram. A 50 kg bag will cover 15-20 square meters, so only about half a bag would be required to do an 8 square meter area. Mortars are often packaged in multi-wall bags that include a plastic layer to reduce the infiltration of water vapor. Mortar, like any cement-based product, will absorb moisture from the air and degrade over time. Two layers of plastic bags tightly sealed with twist ties will keep leftover mortar fresh for future projects.
