How much does a cubic yard of concrete weight underwater?
A cubic yard of concrete weighs the same underwater as it does on land, which is approximately 4,000 to 4,500 pounds. The weight is determined by the density of the concrete mix, not the surrounding environment.
Can you pour a concrete sidewalk over top of another existing concrete sidewalk?
No do to the concrete settling the concrete on top would split
When did the Romans develop good harbors?
When they invented concrete. Roman concrete set underwater and was used to build harbours.
Should you put a sealer on concrete flooring?
Yes, so that the concrete doesn't break or split.
What is underwater concrete?
Underwater concrete is a specialized type of concrete designed for use in submerged environments, such as in marine construction projects like bridges, piers, and underwater foundations. It is formulated to maintain its integrity and performance when placed underwater, often incorporating additives to enhance workability, reduce water permeability, and improve resistance to erosion and chemical attack. This type of concrete can be poured directly into water or used with techniques like tremie methods to ensure proper placement without washout. Its unique properties make it essential for ensuring durability and structural stability in aquatic settings.
Why can concrete cure underwater?
Yes it can. It actually cures harder under water then above it. True.
What has the author Frederick Roland Bennett written?
Frederick Roland Bennett has written: 'Shear strength of lightweight concrete by split-tensile methods' -- subject(s): Lightweight concrete, Testing, Concrete
How did Romans build foundations in water?
To build underwater foundations for the docks of some ports the Romans used concrete.
How many concrete structures were there in ancient Rome?
There is not a precise count. The Romans used concrete extensively. They used it for large buildings, bridges, and aqueducts though stone and brick were used as well in a concrete construction. As Roman concrete also set underwater, it was also used to build ports.The biggest building which was made mainly in concrete is the Colosseum.
What uses does Heavyweight concrete have other than radiation shielding?
It is also used for bridge counter-weight and for weighting down underwater pipelines etc.....Dan
What is split tensile test?
Tensile strength is one of the basic and important properties of the concrete. The concrete is not usually expected to resist the direct tension because of its low tensile strength and brittle nature. However, the determination of tensile strength of concrete is necessary to determine the load at which the concrete members may crack. The cracking is a form of tension failure.
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
