Concrete and Cement

Parent Category: Building and Carpentry
Buildings today cannot go without concrete and cement. Cement mixed with water, reinforcing steel, sand and gravel, binds all of these components together. When dried, it becomes hard as a rock, which is perfect for buildings and infrastructure.
Some elastomeric material is advisable, to cater to differential thermal behaviour of the two materials.
You are able to purchase 10 kg (22.6 lbs) ready-mix tubes of  concrete fro good DIY/building supply store
you need to have a ''keyway''---that is a groove in the base concrete,can be cut in if concrete has set,if not set,oil a 2x4lightly(lightly) & imbed it into the base concrete flush.
4x8x16, solid light weight (you can find at Lowe's and HD) - 27 lbs when dry, 28 lbs when wet
This is a heavy gauge polythene laid under the concrete to stop dampness rising upwards
to figure it out you just need to take the weight of the cinderblock and minus the weight of the same amount of water. to find that get a tub of water filled to the brim and put it in some thing that can catch the water that spills out when you put the cinderblock in the tub. then all you have to do...
Well it depends what size it is if your looking for kg's it the mass the weight is kg's multiplied by 10
you are going to want at least a 6 inch base of packed stone, then  at least six inches of concrete reinforced with either rebar or  highway rated mesh.
  Thaks a lot it has shown me how the friends concrete dyo falls apart   I am now trying to be a dyo   Whats the secret time to to final finish with the float( wooden /steel   whats the rule of thumb to take out the edging   thanks Dave
== Answer: ==   == 42.5 lbs. (19 kgs.) ==
a yard of concrete is 3'x3'x3', so 36"x36"x36", 36 divided by 3 is  12, so you would get 12 36x36 slabs out of a yard, thats 9 square  feet per slab, multiply that by 12 and you have 108 sqft
  == Answer ==   the concrete should be 6" according to this site http://www.de-fontenay.com/poolcon4.htm
depends on bad size and product, the calculations for what you are  asking are on the bags back and product websites
moisture creates calcium to react with concrete
First, do NOT wax laminate floors in the first place! They are not supposed to be waxed. However, if you are in a situation like I am, namely the previous owners waxed your laminate and now it looks awful, you can try scraping the wax up with a credit card or store "club" card, or hitting it with a...
Epoxy works great if there is no deflection, (higher and lower side). However, i would suggest doing it during a cooler time of year when the concrete is contracted to a point where the joint is at its largest.Durring summer months there is a product made called SIKAFLEX. This maintains great...
muriatic acid should not cause discolouration to concrete it will eat it away though.
12 inches maximum asphalt pavement thickness allowed for an asphalt over soil instalation. 12 inches.
Definition of the amount of concrete that (by volume) will fill on cubic yard of space.
It depends on your mix -- those darned college kids keep making canoes out of concrete that floats (http://content.asce.org/conferences/nccc2010/) but they're using admixtures that the normal world can only dream of. Normal concrete is about 145lbs per cubic foot, and normal lightweight concrete...

Yes. The vinyl has to be specially cleaned and treated in order for the adhesive to stick. Special products and instructions are available at most home improvement stores.
It depends how hot it is outside...In Arizona in the summer you can remove them the same day (4 or 5 hours after finishing the floor)....otherwise I would wait until the next day. You must also remember that concrete does not cure based off heat and "drying" out. Concrete cures and gains its...
The importance of slump test in concrete work is to ensure  consistency in the concrete. The test measures the workability of  the concrete.
If you pour to a 4" depth, you will need at least 24.89 cubic yards. If you use a 6" depth, you will need at least 37.33 cubic yards.
We need to know the thickness or depth in inches. Cement companies can give you an estimate if at the time of your order, you give them the length, width, and thickness of the pour, if it's 4", 6" or whatever deep.
It is possible to but an addition with a crawl space over a  driveway. However, the concrete will need to be broken up and  removed first.
Yes, muriatic acid generally does a fairly good job of it. Try a little at a time for starters, though, to see if it is doing what you want it to.
The amount of rebar depends on the thickness of what you are making. All three dimensions.
27 cu. ft in 1 yard, 4 into 12 3 times, 27x3=81. 81 sq. ft .
If the condition of the existing foundation is determined to be sound for the LIFE of the proposed structure and the proposed structure does not exceed the limitations of the existing structure. (example- putting a 2 story garage/apt on a foundation designed for the load of a one story garage)
There are many kinds of 'blocks' - even the CMU comes in a variety of materials and weights vary depending who makes them. - AS a rule of thumb , there are 90 CMU's on a standard pallet and they will weigh about 3,600 pounds. - (Could be 100 or so either way.)
The standard mix is 123 That is one cement two sand three gravel
Thin set mortar? It is what you use to lay ceramic tile.
The "Field" or "mat" is normally 16" on center. Some engineers will specify 12" centers. It really depends on your application.
The docks in Pompeii are concrete, the coliseum in Rome uses it.
If you're dealing with a new slab, you must wait a minimum of 28 days, preferably two months, for the floor to cure and dry thoroughly before applying a garage floor coating.
1. Best way is in the form a an integral concrete color. This is usually in the form of bags added at the concrete plant. Usually cheaper if the concrete supplier will allow you to buy the bags yourself and add them on-site.2. Second choice is a stain. These are easier, can be put on after the...
If it is stamped and stamped only you want there is no cheap way. Do not try this yourself if you have no concrete experience. Less expensive decorative options are available including exposed, color, broomed, paving stones, etc. For a real decorative look mix a couple of designs. For example an...
its is something that neutralizes the concrete! :)
  bent and tied metal rebar for the slab-to-wall connection at all filled cells bent metal straps embedded into the lintel to connect roof to wall
2" based strictly on the slab thickness. However, it may be governed by form spacing, rebar spacing or rebar clearance to the forms.
For a 16' x 24' slab with a depth of 4", you would need a minimum of 4.74 cubic yards.
Assuming you pour to a thickness of 4", this area requires 4.75 cubic yards.
A 52' x 48' by 4" pad requires 30.8 cubic yards. If you go up to 6" thick you would need 46.2 cubic yards.
Type your answer here... .675 cu. ft
Crushed concrete is sold by the ton. One dumptruck will haul between 13 and 15 tons. Your driveway should take around 30 tons if covered 4" thick.
It would vary with the cost of concrete in your area and how thick the slab would be. I assume by the size that you are building a shop or similar. If so, I would go at least 6" thick. 1 cubic yard at 6" thick covers 6 square yards. So, you will get 6 square yards of concrete out of 1 cubic yard. ...
one way is to build a stem wall or stud wall using pressure treated bottom chords.and T-11 other exterior rated siding. another solution would be to check with a manufactured home supplier about skirting, this is depending on the height required.
The specific gravity of materials tell us how many times is the material heavier than water. The higher the specific gravity of a material the higher the density of concrete made with and the higher will be the force require to crush it and the higher will be the corresponding strenght of the...
  10 bags will give you 6'2/3", seven bags will give you 11 bags will give you 7'1/3". Each bag is 2/3 cu feet.
By the yard ... 4" thick and an area 3' by 3' square.
Approximately 44-45 yards would be required to place a 4" thick slab on a 3000SF area. There are 27 cubic feet in a cubic yard, and at 4" thick there is 3 square feet of coverage in a cubic foot: [# SF] x [# inches thick / 12 inches per foot] / [27 cubic feet per yard] 3000 x 4/12 / 27 = 37 yards ...
Pick a corner, measure 3 feet on one leg, measure 4 feet on the other leg and it should be 5 feet on the diagonal. That means the form is square. Works for a square or rectangle or for an L or complicated layouts. For a square or rectangle you can measure corner to corner and the measurements...
Yes concrete is very strong.
It could be 65" (b wall - 5.5" wall thickness), or 66.5" (c wall -  6.25" wall thickness).
L = length of the house W = width of the house H = height of the walls Exterior area of the four walls is [ (2H) times (L + W) ] .
Cement is the only material in cement. -However, concrete is made of cement, sand, gravel and water .
  $70 - $100 per cubic yard depending on supplier.
  3000 psi. with 3/4 rock should do it . but you could go higher psi which would be over kill.
You will get not 2.3 cu ft you will probably need at least 50 to 60 bags to make cubic yard..
I am having one done at this very moment. It will be $2700 total, and that includes dirt work. I am told that is a fair price.
Steel re-inforcing in concrete should always be placed 1/3 of the depth from the bottom. A 6" thick slab would have the steel placed 2" off the bottom.
Without knowing the area, there is no way to answer.
Check out these sites. This has a concrete calculator that will tell you what you need.   http://www.raineri-materials.com/redimix/rm-calc.htm   http://www.hansonaggeast.com/calc_concrete.cfm
what is a ytransfer slab
wood, straw and mud (bricks), fiberglass, etc.
Generally 30 days brings concrete to to specified compression strength. Concrete may take 30 years to cure.    AnswerConcrete will harden to about 80% strength in 2-3 days and close to 100% strength in 28 days. Concrete driveways should be towards the latter end prior to driving on them.  ...
Lots... LOL you mean by hand and a wheel barow? I you need to do it more then lets say 10 times. I would bother and would order a truck
It depends on how large a hole you want to leave One way is to get the smallest concrete cutting disk you can hire and cut a square piece of concrete with the old anchor in it drill some holes in the side of the newly exposed concrete put pins in them sticking out so that when you refill the hole...
Hello, I just had a 800 sq. ft. rectangular patio with rounded corners and a stamped pattern put into it for $5200. We paid an additional $250 to have a pattern of diagonal lines in 4' x 4' squares put into it. It is a light sandstone color. I was told also that darker colors will cost more because...
question is not very clear, but if you are talking about Alkali bypass filter then reply is as below; - Kiln gases are bypassed to reduce alkali concentration in the kiln system. - alkali come from rawmaterial (mainly from limestone), fuel used or additive. - This alkali get absorbed in the...
