Concrete mix design. Concrete admixtures help to enable the use of these alternate pozzolans … more.
How pre-applied membranes work Pre-applied membranes are laid down before the foundation is poured. The membrane is placed directly against the soil retaining systems. The concrete is then poured directly onto the membrane. This benefit alone can result in significant cost and time savings for contractors on site.
At the turn of the century, the company pioneered the use of steel-reinforced concrete to create safer, stronger, and more efficient buildings. The project includes the creation of three large habitats with essentially no straight edges, including a main habitat consisting of 680 cubic yards of concrete and 355 tons of rebar.
Then after architect consult with a structural engineer and MEP engineer for details of the reinforcements and other detail for use, how deep your foundation will be, the size of gravel to be used, column width, electrical, plumbing, etc. Also, read: IS 516:1959 Most Important Point (Method of Tests For Strength of Concrete).
What Is Concrete Topping? A Concrete topping is a process of laying out a layer of high strength concrete on the old worn-out layer of the concrete. It is nothing but placing a layer of concrete over the existing slab in order to give a finished floor surface on the old layer of concrete. 25 to 50 mm ).
Concrete construction innovations. Control flow concrete construction. Mass pours. One of the latest innovations in concrete construction is the development of an entirely new type of concrete. One of the latest innovations in concrete construction is the development of an entirely new type of concrete.
What Is Cast-In-Situ Concrete? Cast-in-situ concrete is prepared, placed, and finished on the construction site. Another name of cast-in-situ concrete is poured-in-place concrete. Generally, concrete slabs, concretefoundations , beam, column, wall, roof, etc., What Is Cast in Place Concrete?
Using control flow concrete for top down construction. This concrete construction method allows for above ground construction work to be carried out at the same time as excavation of the basement, resulting in significant time savings. Construction of concrete floor slabs. Concrete challenges in top down construction.
Using control flow concrete for top down construction. Commonly used in urban areas, top down construction is often used for high rise buildings with deep basements and for underground structures such as car parks and transit systems. . Construction of concrete floor slabs. Concrete challenges in top down construction.
The word Monolithic means “all in a single pour” so in construction where Monolithic Slab is used the foundation is made in one single pour that is made up of a layer of a concrete slab with thicker area under the load-bearing walls and all the edges of the perimeter to replace the footer.
