FAQ

I have a patio that is half cement and half open space. I want to put cement blocks/slabs in the open space. I've had mulch and rock; however, I am tired of that look. I was told I could not cement the open space because it will crack in the future so I am wondering if I can put sand under cement slabs/blocks in the open space. Someone suggested I put white rock, but I want a flat surface so that my niece and play back there. Any suggestions, please?

You are going have to put some form of bedding like crushed stone under the sand first sand itself won't do the job as for cement that won't do either using concrete is the preferred method again laying on a bedding of crushed stone you don't specify the area you want to cover over so all I can say is you will need to excavate the area firstly to a depth of 6 inches minimum that will allow for 2 inches of crushed stone a weed blocker/plastic sheeting 2 inches of sand and cement dry mix and using a slab 2 inches deep to rest on there.Also a slight slope will need to be made to allow surface water run away from house and not be allowed flow back towards your patio.If you decide to use concrete again cut out 6 inches of ground and 3 inches of crushed stone weed blocker and a concrete slab when pouring concrete try to keep it semi dry,too much water is not good as when concrete drys it shrinks and can cause cracking later,I don't think you would have to re-inforce it as you won't be using the car on there ok.

How does cement work?

When water is added it starts a process beginning with the formation of short hexagonal crystals. it is this process of crystal formation which begins the setting process and usually is substantially complete after 24 hours. However, the crystals continue to form and fill up the spaces for weeks and even months as long as the cement is not allowed to dry out. When mixing cement it is recommended to keep it wet for at least 3 days, when it reaches maybe 80% of its final strength, but a week to ten days is better. Cement will continue to harden for several years. The strongest cement you can get is that which sets up underwater and is never allowed to dry out.

know the cement but I want to know the exact definition in engineering view.?

cement is a cementing material or binding material used in engineering construction. It is manufactured from calcareous substance and is many respects to the strongly limes but possessing far greater hydraulic properties. thanks.

Can some one tell me how to make a cement table/table top? Any help is appreciated, Thank You.Barbaralynn

take your table top you have now if that is the desired size (if not right size take 2 pieces of plywood that is the size screw them together) and put pieces of wood (forms) around the outside of it that go up about 4 inches. then get yourself some self leveling cement at any home improvement store and mix as directed on package. you can also tint the cement to a color if you ask at the store what to use. then pour it into your form and allow proper drying time. when dry remove the forms and lightly sand the cement to the shape and texture you want it to be on the edges. good luck =)

I hope you can help me with my question regarding the Cement-lined pipe.The contractor in a water treatment plant changed the specified Stanless steel pipe to Cement-lined DI pipe.This will be used in air application from blower, air will have a velocity of 23m/s.Is this an ideal application for Cement-Lined Ductile Iron Pipe??

I would not accept the cement lined pipe. It is subject to cracks in the cement lining as well as spalling or loss of some of the lining over time. The joints in the pipe are difficult to coat and tend to be a point of high corrosion.

Front porch cement is all pited. I try some cement product they seam to flake off after a year or two. Or is there a newer cement product out now

You could get some of those plastic boards they make for decks and try to attach to your porch. I don't know if the additional thickness will cause you any problems. If you want to try a cement product, be sure to clean the old surface well and remove all the loose materials. If you are using a cement product that is trowelled in place, you should put an epoxy bonding agent down first, and your minimum thickness should probably be 1 (thicker will be better). Cure the concrete with wet rags for a couple of days for best strength with less surface cracking.

what's the difference between cement and mortor mix?

Cement has a mixture of portland cement, sand, and gravel. Mortar does not use gravel, just more sand, giving it a more spreadable viscosity.

My e-reader is malfunctioning due to a small metal hinge (which protrudes from the case of the unit) and is triggering electrical current and causing a short. My purpose is not to adhere anything, but actually to apply this glue to dry as a kind of non conductive coating. If this doesn't work, is there another kind of household product that someone can recommend?

No. Contact cement does not conduct electricity. It just makes a firm bond between two different materials/.
