Q: i am making a small crucible and i wanted to know simply, if masonry cement is qualified to accept temperatures of over 3000 degrees if it isnt then is there one i can make at home from realy simple to find materials?: i would think that concrete would crack very easy at those temperatures.

Q: We have an awkward spot in our basement heading down the stairs. We barely have enough spaace to bring bigger items down. We would like to put a 3/4 drywall and glue it to the wall. Is this possible? Can I just use liquid nails?: Cement is notorious for passing on continuous moisture. Wallboard will become somewhat of a wick, sucking the moisture from the cement, breaking down the drywall, but often before that, become a source for mold buildup - very unhealthy. Generally, on cement/concrete, you would attach furring strips (1 x 2's often) to attach to the cement, then, the wallboard onto these. However, given space is an issue, in getting up/down the stairs, you do not want to add bulk to your walls. Stucco would work OR you can just paint or stain the cement. Make it a focal point with a decorative paint job, or an artistic element.

Q: My contractor charged me $450 for cement for laying out 600 sq ft tile on the floor. He told me he used 27 bags. This is in addition to grout. Cost seems very high. How many bags is typically needed?Thanks a lot: Sam e mail me back thru my avatar and we ll get to the bottom of this. Somethings wrong. I have questions for you. You say cement, is that cement for a mud bed? Or do you mean cement ( thin set) to glue the tile down with? Some things not right either way.. Once I know what was what I can give you very close estimates on what you need. Edit/add on If its thin set to glue tile down and you did it with no waste ( throwing a bit away at the end of the day) you ll use 8 1/2 50# bags.. Lets just round it to 10 - 50# bags to make it even.. I m going to go high on a price of 15$ a 50# bag of a white latex modified thin set.. Thats $150 when I went to school.. Now where he came up with 450$ is beyond me. Thats why I d like to know if its the thinset your saying or regular cement for a mud floor. Then he d have to add sand onto this because a proper mud job is 2ns sand and Type 1 Portland cement .. E mail me Sam GL

Q: I am thinking about a career in driving a cement truck. Can somebody tell me the upside and downside of this career? I have a class B licenses now so all I need to do is add tanker endorsement to it.: ok, if u r driving a cement truck y do u think u need a tanker endorsment? A cement truck is a 10+ wheeled straight truck with a cement mixer on back...it needs class b with airbrake (if equipped) endorsment.

Q: why is cement used for ? binding aggregate and sand or is used for increasing tensile strength?: interesting i dont know

Q: I want to rebuild my porch, It's relatively small.What kind of cement should I purchase.The more info. the better ;): You can buy cement powder at your local home store. The price varies on the types of aggregates. You'd want the more coarse aggregate as they function like support but they are more expensive. Otherwise use rebars when you mix them if you buy the cheaper powder. You have to have a big enough mixer to mix everything at once. Otherwise, it would be a pain to do it and very messy.

Q: I know this is a funny question but my friend and i have wondered this.Thanks and God Bless!: In regards to a driveway? I personally have a gravel driveway and love it!! I dont have to worry about cracks or cosmetic defects. I do need to weed treat it once and a while, but thats nothing major. Its also a lot cheaper than cement. Check with your city ordinances, some cities do not allow gravel driveways. They are phasing to finished surfaces. (ie: brick, cement, asphalt, etc)

Q: I'm wanting to get the quot;DIY Belgian-Style Stone Moldquot; by Pathmate to create a back yard area for my husband and I to enjoy the out doors some. One of the things I'm was wanting to do is to have all the concrete stones be a nice dark blue color so it would look good with the house and any outside furniture. I really don't want to just apply a coat of paint the surface of the stones. And i did read somewhere online that I could mix latex paint with water and concrete but i cant find any photos with the results. any suggestions? I do want this project to be as inexpensive as possible please help: Maybe you could ask a concrete company close to you if you could buy a small amount of color pigment. They have charts there so you can see the colors and I am sure since you don't need that much for your project (it is not a whole driveway) they might sell you some. Ths way you know how it would look and that it works with concrete.
