What else can I help you with?
How do you make reinforced concrete?
Reinforced concrete is just normal concrete with steel reinforement placed inside.
What is the R-value of Normal Weight Concrete per inch of material?
Normal Weight Concrete at 150 pcf has an R value of 1.22 per inch thickness
What is rich mix concrete design compare to normal mix?
it has more cement than the normal mix
Why do you have cracks in concrete?
Concrete cracks. You can do everything right and use the best materials, it will still have hairline cracks. It's normal.
What is the ratio of steel in concrete?
As per the civil engineering thumb rule, weight of steel for one cubic meter of concrete is 100kgs to 130 kgs for normal structures

What kind of houses do they have in iceland?
Normal houses of bricks, concrete, wood etc.
What kind of concrete to use for crafts?
I took an art course using concrete and it was normal everyday concrete. We were making stepping stones.
What is the normal size of a concrete block?
8"X16"

Can concrete tremie mix be used in normal structures?
Tremie is not a "mix" but rather is a method of placing concrete underwater. It would seem to me, and I work in construction, that you would be needlessly adding cost. Why not simply use "normal" concrete for "normal" structures? Here is a link: http://www.concreteconstruction.net/industry-news.asp?sectionID=718&articleID=243445
What is the difference between a normal weight concrete and a lightweight concrete by volume?
The main difference between normal weight concrete and lightweight concrete by volume is the density of the aggregate used in the mix. Normal weight concrete contains aggregate with a density around 2400 kg/m3, while lightweight concrete uses lightweight aggregate such as expanded clay, shale, or shale to reduce the overall density of the concrete. The reduced density of lightweight concrete makes it more suitable for applications where weight is a concern, such as in construction of high-rise buildings or for insulation purposes.
What is high performance of concrete in civil engineering?
Normal use concrete has a compressive strength of 3-5 ksi (concrete is essentially useless in tension). Though in skyscrapers, they are beginning to use concrete with strengths upto 14 ksi.
What is high strength concrete?
Concrete with compressive strength more than 55 MPa is known as high strength concrete.It is used in the construction of bridges, dams. etc.,High strength concrete is produced by adding normal constituents of concrete with admixtures.
Why the size of concrete cubes are 150mm?
Basically, the force supplied by a concrete compression machine is a definite value. For normal concrete strength application, say below 50MPa, the stress produced by a 150mmx150mmx150mm cube is sufficient for the machine to crush the concrete sample. However, if the designed concrete strength is 100MPa, under the same force (about 2,000kN) supplied by the machine, the stress under a 150mmx150mmx150mm cube is not sufficient to crush the concrete cube. Therefore, 100mmx100mmx100mm concrete cubes are used instead to increase the applied stress to crush the concrete cubes. For normal concrete strength, the cube size of 150mmx150mmx150mm is already sufficient for the crushing strength of the machine.
