Q:what r the raw materials used to make cement?
Cement - the grey powder that is mixed with sand and water and sometimes gravel - is gypsum that is fired at high temperature. Lime can be used, but it has to be slaked and treated in special ways.
Q:put down cement backerboard without adhessive?
You should use screws to adhere it, not adhesive. the screws will pull the floor and backer board tightly together. They make screws specifically for this. Make sure you screw them down all the way before tiling, or the tiles will be uneven and possibly crack.
Q:My dog swallowed rubber cement!?
Take it to a emergency hospital. Yes, rubber cement being swallowed would be harmful to both humans or other mammals. I suggest you first call a vet to make sure, and then do as they instruct, even if it would be just as the following said take it to the emergency hospital. I suggest calling the vet first, just in case.
Q:Cement silo opening clogged?
Maybe you could get a claw on a pole manufactured and feed it down through the cement and extract it from top.
Q:Water-based cement?
Water based cement can be thinned with water and cleaned up quickly (if you spill or are sloppy with it) with water. Once it dries completely you can't clean it up with water anymore. Not as messy as regular glue.
Q:Approximate Cost to Replace Cement Shower With Either Tile or Modern Stall?
By cement slab you refer to the concrete basement floor with a drain in it? Nothing to tear out. A contractor will install a shower pan. Either custom made or a prefab pan and tie into the existing drain. If you want to relocate the shower then he will jack hammer up the slab and run the drain. Save money by having the shower in the same place. For just the shower pan and walls framed, covered with backer board, tile tie into existing hot and cold water supply figure about $4000. If you want to use custom materials like granite and limestone tiles add $1000. Also plan to install an exhaust fan for the steam. If you can be happy with a prefab fiberglass surround it will be half the cost.
Q:How much to fix cement steps?
Use the Following Steps to fix cement steps : Remove Loose Pieces and Debris Pressure Wash the Cement Tape Off the Edges Prepare the Cement Patch Mix Apply the Cement Mix Fill the Holes Add a Second Coat Create a Wetter Consistency Spray Water Use a Cement Finishing Broom Work the Cement Into the Pores Add the Skim Coat Shape the Rounded Portions
