Q: We've tried to fill it with some kind of putty-type compound. However, that didn't work.The bowl is a quot;crumblyquot; cement bowl. What's the best thing to use to fix this problem?: try filling the holes with bathroom caulking.

Q: Is Pozzolan cement inferior to Portland cement? Please explain.?: Portland cement evolved from pozzolan cement, so most likely, yes.

Q: I was planning on using Hardie Backer, but the instruction state that Hardie Backer is not designed for use over concrete. I need to raise the finished floor height about one inch to match an existing floor. If I can use cement backer board, do I use thin set to attach the backer board to the concrete? If I can't use it, what are my options?: Putting down backer board is a waste of time and money when going over a smooth cement floor. Backer board is used to stiffen up an existing wooden floor or wall. It can also be used when planning a shower to allow for build up to slope to a drain. As far as sweating is concerned backer board will not prevent it if it is a problem. It will just make your floor thicker. The sweat comes from the air contact with a cooler floor surface it is not from water seeping through the floor. A dehumidifier will help to solve this problem in the summer months. Make sure you use a sufficient base of thinset (1/4 inch trowel minimum, 1/2 inch if uneven or rough spots). Mixing a latex additive to the grout is also a good idea in below grade and outdoor grouting situations.

Q: On the gas tank of my motorcycles is edged rubber and edged thin steel. The edged rubber slides into the edge of the steel. Some of the rubber has come off the edge of the steel, and I was wondering how could I glue it. I thought of rubber cement, but I don't know. Also should I prime the steel by taking some light sandpaper to it? Thanks.: use some good super glue.. it makes a stronger bond. and the excess can be sanded off after it dries, its better to over apply than to under apply.

Q: cement industries: Although I am not first hand in the cement/concrete industry, water extends the tooling's life and most important, it keeps the dust down so you have a lesser chance of getting lung disease from the dust. I forget what it's called right now. We do a lot of core drilling in our line of work those are the reasons for the water.

Q: ive been waterproofing basements for 13 years. we jackhammer concret all day and the basements get very dusty. masks are worn but their not 100%: i like tiny's answer... though, i don't do that stuff... concrete is very bad for you. not QUITE as bad as asbestos, but damned close to it. you can get emphysema, lung cancer, CONCRETE OPHTHALMIA etc etc from prolonged exposure, just like you can get concrete poisoning from laying wet concrete and not washing it off of you. i'd find a new line of work and do something to clean out your lungs.. i hope you aren't a smoker on top of that. as far as masks go, that obviously helps, but it depends on the quality of the mask obviously. I would assume you know the difference -most likely better than i would.

Q: i need to know the difference and likeliness of cement kiln and incinerator. in what way they are diffferent from each other, and in what way they have similaritygt;?since i already looked in wikipedia, the incinerator and cement kiln both are a process of thermal waste management. thank you: Cement Kiln is used in cement industry to melt and mix different sand types of which cement is composed of, whereas incinerators are used to burn out solid wastes which can not be dumped. Hope thats enough. Bye.

Q: Im trying to level my floor with self levelling cement. I know its supposed to be runny but i may have put too much water on it. Unfortunately i already dumped it on the floor. Will it eventually dry up.: If you added too much it will flake when you step on it. If this is the case it won't be any fun to remove, but it will come up easy and you can start again.

Q: What is the density of cement?: I will answer your question directly, then answer the question I think you are asking. Cement is a gray powder that is mixed with water and aggregate to make concrete. Cement and concrete are 2 different things. Cement is to concrete as flour is to cake. With that said, cement (the powder) has a specific gravity of 3.15, which means it's density is 3.15 times that of water. Water has a density of 62.4 pounds per cubic foot, so cement has a density of 196.6 pounds per cubic foot. If you actually mean concrete, which is the hard grey stuff, then it has a density of about 150 pounds per cubic foot. Hope that's what you were referring to.

Q: that is 40% cement?: .25(30)=x =7.5 and .4(30+y)=x+y 1) substitute x=7.5 into 2nd equation .4(30+y)=7.5+y 2) 12+.4y=7.5+y 3) 12.5-7.5=y-.4y 4) 4.5=.6y 5) (4.5)/.6=y 6) y= 7.5kg of cement added (37.5kg cement MIX) To check answer: original 7.5kg of pure cement(25% of 30kg) plus the added 7.5kg of pure cement = 15kg of pure cement. 30kg total mix plus added 7.5kg of pure cement = 37.5kg of cement mix. (15kg of pure cement)/(37.5kg of cement mix) = .4 or 40%
