Will strength of concrete mix will decrease if hot water is used?
Nmadhukar
As long as the water is liquid, the strength of the finished product will not be diminished by the water temperature.

Rebar is used to?
Rebar is used to give strength to masonry and concrete constructions. Masonry is this case is concrete blocks. Concrete, block or cast in place, is good for compression forces and not tension. Steel is good in tension or tensile forces and not compression. By combining the constructive elements of concrete with steel, thus reinforced concrete, you get the strengths of both in one medium.
Does blue metal absorb water?
Yes, Usually it absorbs water of 0.5% to 1 % max. This is used for correcting the water content used for producing the mix concrete.
What materials were used when frank Lloyd wright built falling water?
reinforced concrete and stone
What is concrete in architecture?
Concrete is the name commonly given to a mixture between a cementitious material and an aggregate with water added to chemically bond the materials during a curing process.Commonly used materials are portland cement and granite pebbles, with sand and other additives added to improve the concrete quality.The Roman Empire pioneered the use of concrete as a building material, as well as the use of arches to deal with large spans between columns. Concrete deals very well with compressive forces (pushing), but it will not work well against tension and torsion (pulling and turning). To improve this tensile strength; steel bars or cables are usually embedded into the concrete where tension or torsion is likely to occur.For a more complete explanation about concrete, you may try this link:http://en.wikipedia.org/wiki/ConcreteGood luck!
What paint should be used on concrete to resist alkali?
Paints to be used on concrete should be made especially for concrete. This is a very hard surface to cover and keep covered so it is very important a paint made especially for concrete is used.
Why fibers are used in concrete?
to increase the strength of the material and decrease the weight of the material
Why is strength of concrete so important in construction?
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
What is the effect of hydration on strength of a concrete?
Excess water (over hydration) causes weak concrete. The water in concrete is there to start a chemical process which results in the hardening process. The excess water is not used in the chemical process and results in a weakened concrete.
Why are bridges made of steel and concrete?
Steel is used for its high tensile strength and the concrete is used for its high compression strength.
What name are concrete admixture?
Mineral admixture are those which are mixed with concrete ingredients and spread through out the body of concrete to favourably modify the properties of concrete . the commonly used mineral admixture are1. Fly ash2. Silica fume3. Rice Husk ash4. matakaoline
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.
When the process of curing the concrete absorb water?
Water chemically reacts with the cement to form a new compound. The resulting concrete gradually reaches full strength over 28 days, but most of the strength comes in the first 3 days, so that is when most of the water is used and needed.
What is ductility index of concrete. Where this index is to be used?
it is the ratio of tensile strength to the flexural strength
What does newton mean in concrete strength?
newton mean in concrete it is used for bearing for exemple mark
How much does 6500 psi concrete weigh?
The weight of concrete is determined by its density, which is typically around 150 lbs/ft³. However, the density of concrete can vary depending on the type and amount of aggregate used, as well as the water-to-cement ratio. Additionally, the weight of concrete can also be affected by the compressive strength of the concrete, with higher strength concrete often weighing more than lower strength concrete. Therefore, the weight of 6,500 psi concrete can vary, but it is typically around 150 lbs/ft
Why was the steel and concrete used in the Golden Gate Bridge?
strength
What is water to cement ratio?
Water/cement ratio law states that the strength of concrete is only dependent upon water/cement ratio provided the mix is workable.Strength of concrete primarily depends upon the strength of cement paste.Similarly, the strength of the paste increases with cement content and decreases with air and water content.
