What else can I help you with?
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
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.
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.
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
Did roman concrete help people?
Roman concrete was neither better nor worse. It was different. It was as strong as modern concrete and it set underwater. It was less fluid and it had to be layered by hand. The Romans did not use reinforced concrete. Roman concrete was made by mixing pozzonlana (an active component of volcanic pumices and ashes) with lime and adding an aggregate to give it body. This varied depending of the consistency or weight. It could be pottery sherds, crushed brick or crushed rock.
