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:Im in the middle of a renovation and the tiler has told me that Natural stone tiles 18x18 should not be installed on a cement board wall that has been primed. This application is for a shower/steam room. He has told me that i should rip down the cement board and replace with new unprimed boards. Any advice. The tile is planning on using Flextile 52. Please advice if the boards need to be replaced. The cement board has had the screws and joints covered with drywall cement and then the entire wall was painted with drywall primer sealer (latex).Thanks: You can do it, but you shouldn't. Especially not in a shower. The primer will prevent the mastic/mortar/thinset from adhering to the cement board. Drywall compound should not be used in cement board for a tiling application, a fiberglass mesh tape and thinset to reinforce the joints, and the thinset will covewr the nails. Your best bet would be to do as the tiler says (I know that the cement board isn't cheap, but would you rather have the tile come crashing down on you in the middle of your shower?), though you may be able to remove enough of the primer and compound through muscle power. (buy a decent dust mask. silica dust and fiberglass are no fun to cough up) Another alternative, go over the offending cement board with another layer of 1/4 inch cement board, staggering your joints between the layers. Run this by your tiler, he may agree... if nothing else, the staggered joints will lessen the chance of the joints cracking.

Q:Took out old ceramic tile that was embedded in concrete. Older home original tile. Now there is a big hao between the floor and walk 2 DIFFERENT sizes.Most of the Flor is 1 inch 3mm. There is another srip that runs behind vanity that a 2quot;. The new tile is small square and only maybe 1/4 in thick I d that.Is there 1quot; cement board? What do I do if there is a gap between tile and floor wall? I do t want water getting in from mopping or wet making mold. Also what do I do about the part that is a larger hao by 1/2 in than rest of floor? See pictures.: Well to start, I would prep the floor by thin-setting and nailing/screwing cement board to the floor. Use a larger trowel (maybe 1/4x3/8) to help bridge the gaps for a solid bond between the wood and the cement board. Afterwards, use a self leveling compound to eliminate any uneven gaps and to raise the floor level to high high you need it. If the leveler will run under the house from the gaps, use tape or other materials to keep it from flowing through. Use as much leveler as you need to make the height where you desire...and and easy job tiling with the new level floor.

Q:know the cement but I want to know the exact definition in engineering view.?: Cement generally is a powder which when mix with water, chemically bonds with it and forms a paste and eventually hardens. Cement bonds aggregates (sand and gravel) to form concrete. When a steel is used to reinforce concrete, this is called reinforced concrete. Cement is used in plastering walls, filling hollow blocks, tile setting, floor screeding and others. Cement is always part of everyday life in construction from foundation to finishing.

Q:What are the requirements for the strength grade of ordinary concrete structures: Cement is a hydraulic cementitious material, according to the provisions of the amount of water and mix well with the slurry, wrapped with fine particles all the surface and fine voids constitute mortar, mortar wrapped with coarse particles all the surface and the gap constitutes a concrete, cement and water to be combined The formation of crystalline calcium silicate, cement hydration all completed the day, that is, when the concrete to meet the expected strength of the time

Q:Let's see if I can get the right. I have 12 cement columns which are three meters high (on third floor) and I want to put wooden columns on top of them 3 meters high. (fourth floor) The trusses will be on top of the wooden column. I'm concerned about how to connect the wooden columns to the cement columns so that they are stable and secure?: If the wooden columns are square and a standard size, use a bracket designed for deck construction. They are made of galvanized sheet steel and are bolted down to the concrete in the center. Look into an epoxy product (maybe 3M) that will allow you to use a stud to hold the steel bracket in the concrete. Often, cracks occur in a narrow column if an old fashioned lag anchor or lag type stud is used.

Q:Are they just two different terms for the same thing?: Concrete is a mixture of cement, sand, water, and rocks. Cement is a fine powdery limestone dust. Cement needs the aggregate materials to hold together.

Q:How does the cement produce! What matter! Why did she get angry?: Cement - Inorganic cementitious materials Add water into the slurry after mixing, in the air or water hardening, and can sand, stone and other materials firmly cemented together Cement is an important building materials, made of cement mortar or concrete, durable and durable, widely used in civil engineering, water conservancy, defense and other projects

Q:much does 1 cubic foot of portland cement weight in water?: portland cement has a density of 1506 kg/m? 1 ft? = 0.0283 m? that is dry cement, not setup. You didn't specify if it is dry or setup. mass = 1506 kg/m? x 0.0283 m? = 42.6 kg The displaced water weighs: density of water at 20C = 0.998 g/cm? = 998 kg/m? 998 kg/m? x 0.0283 m? = 28.2 kg subtracting, we get 42.6–28.2 = 14.4 kg, or 31.7 lbs. .

Q:I had the foundation repaired in my basement a while back and the dust from the cement is still there, I've washed the floor about 5 times since and it still hasn't come off, got any suggestions about what I should do?: You should flush the roof and all side walls.

Q:BP is currently pumping great quantities of mud into the rupture in the Gulf and plan to dump cement in when the flow permits. Cement has to dry to be effective? So how does it dry under water and the pressures it will encounter at that depth.: Simply put: Cement doesn't 'dry', it hydrates. It's a chemical reaction. the cement combines with water to form crystals that bind it, (and the sand normally mixed in), together. The water becomes part of the 'new rock' formed.
