Concrete: Scientific Principles

Concrete is not as likely to rot, corrode, or decay as other building materials. Concrete has the ability to be molded or cast into almost any desired shape. Building of the molds and casting can occur on the work-site which reduces costs. Concrete is a non-combustible material which makes it fire-safe and able withstand high temperatures.

The density of concrete is 3.15 g/cm 3 while the density of aggregate will vary by the type of stone used. For instance, gravel has a much higher density than vermiculite. The density of a typical concrete mix is 2.4 g/cm 3 or 150 lbs/ft 3. Different mixes of concrete will use more or less aggregate as well.

Caisson (engineering) - Wikipedia

In geotechnical engineering, a caisson (/ ˈ k eɪ s ə n / or / ˈ k eɪ s ɒ n /; borrowed from French caisson, from Italian cassone, meaning large box, an augmentative of cassa) is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the

Typical design problems and solutions for prestressed

The concrete stress being zero, the tensile stress in the ring must also be es sentially zero or compressive, since the con crete strain is likely to still be compressive relative to the conditions of installation, due to creep. But without significant tensile strains in the steel ring, the tendon loads will notbe trans ferred around the hole.

What is Curing of Concrete?- Purpose, Importance, Curing

Curing is the process of maintaining the moisture of freshly placed concrete to complete the hydration process and to ensure proper hardening, attaining desirable strength and durability.. Curing keeps the concrete surface moist and reduces the shrinkage. Curing should be started at the earliest. It has to be started when the surface is hard enough for a person to walk over it without damage

Ringforcement: Annular Strategies Of Reinforcement

An advantage of reinforced 3D cube rings is in effect, to leverage the tensile strength assets upon a compressive space frame of concrete. Yet the inner ring volume of concrete alone, without central bulk, (without a filled "donut hole"), fulfills the significant structural framing.
