Q: You are making 10 tons of concrete that is 47.6% cement by mixing a 20% cement mixture with an 89% cement mixture.a) How much of the 89% cement mixture must you use?b) How much of the 20% cement mixture must you use?Answer in units of tons: a) Let the amount of 89% cement mixture used be X tons Then the amount of 20% cement mixture used will be ( 10 - X) tons 0.89X + 0.20 ( 10 - X) = 10* 0.476 0.89X + 2 - 0.20X = 4.76 0.69X = 2.76 X = 2.76 / 0.69 = 4 ANSWER 4 tons of 89% mixture and 6 tons of 20% mixture

Q: I live in an older house that has cement floors and they sweat bad .Is there anything I can do to make them stop sweating?: There a difference between hydrostatic pressure and moisture in the air causing the dampness. Hydrostatic pressure comes from below ( as Don said) and of course the other is in the air, which can be removed w/ a dehumidifier. The other , I haven t heard of anything that will really stop this. Other than basic landscaping to shed water away and to have your cement floor perimeter cut open and drainage tile installed. To find out which one is your problem, dry off an area of the cement w/ a fan and tape( duct tape) a 1ft x1ft pc of foil on to the cement . Leave for 24 hrs, and if you have a lot of moisture after that, chances are your getting water from under the slab. No flooring , other than ceramic flooring, should ever be put on this type of cement w/ this problem. You ll waste your money. GL

Q: Could you make Portland cement with one component only, excluding the gypsum?: Yes. I worked before in a cement plant (at Tinaan, Naga, Cebu, Philippines). I was a shift control chemist and we fed only one component to the raw grinding process which we deposited to the slurry basin and subsequently mixed it homogeneously at the right proportions before burning in the rotary kiln to produce the clinker. Then in the finish grinding operation, we added the gypsum to control the setting time of the finished product, the cement, at approximately the proportion of 97% clinker and 3% gypsum to produce Type 1 Portland Cement. We were blessed with a very good limestone quarry that approximated almost 75% of Calcium Carbonate to crush and grind and burn to clinker and then grind it to produce cement. So almost everyday, we had only a single component to produce the cement. However, we also had in our feeders aside from the limestone, the marl feeder, the silica feeder and the pyrite cinder feeder to fine tune the raw mix, and especially when we are to produce another type of cement. A good day to you.
