What is the most important Roman invention in construction?
concrete, or the key stone (stone in middle of an arch construction)
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 heavier a steel beam or concrete beam?
Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.
Why should large concrete slabs be laid with expansion so that they are not touching?
because large slabs of concrete have expansion joints between them.
How do expansion joints in a sidewalk keep the concrete from cracking?
The expansion joint in a sidewalk keeps the concrete from cracking just as what its called. It allows the concrete to expand when heated and contract when cold. Without the joint, the concrete will crack and become uneven or mountain up.

1 What does it means SITU concrete Construction?
insitu concrete is any concrete structure that is poured in its desired finished place. ie floor slabs of buildings because they are poured and never moved
Why do you use a construction joint?
Construction joints are very useful, the expansion & contraction made is made in summer & winter season respectiely. In summer coz of temprature concrete get expansion in mm but it damage the structure, that's why construction joint is provided. Sunil Nagargoje TESPL

What is the difference between Structural Concrete and Non structural Concrete?
Structural concrete is used in the construction of buildings, bridges, dams, etc. Typically there are more codes governing the use of concrete as a construction material and the concrete used has higher strength. Non-structural concrete is typically defined as being used for the construction of non structural elements. These could be parking lots, sidewalks, handicap ramps, etc. A lower strength concrete can be used and there are less rules pertaining to its use.
What is an expansion joint in construction?
An "expansion joint" is a joint left in between sections of the same material, like concrete or steel, that allows movement as the material heats up or cools down. Without it, concrete, for example, can expand and crack in hot temperature.
What purpose did ancient Romans use concrete for?
Construction of buildings and ports. Concrete was also used in their domes. The pantheon's dome is constructed of different weights of concrete. Nero's famous dining room was constructed of concrete which enabled it to be designed to rotate.
What is curing why need to curing in buildings?
Curing in buildings is a process that is keeps freshly poured concrete from drying. It is kept at a certain temperature to keep it moist. Curing in buildings is important because it gives concrete what it needs to gain strength properly.
