What is a spun concrete? - Bayt.com Specialties

Spun concrete is a process used to make hollow core, high strength poles, columns and pipes for architectural and civil engineering construction projects. The relatively light weight and intrinsic durability of concrete makes spun concrete ideal for many construction projects and in some cases has replaced steel poles and columns.

Types of Piles: Their Characteristics and General Use

of concrete piles were devised. These early concrete piles were the cast-in-place type. Further development of the concrete pile led to the precast pile and, relatively recently, to the prestressed concrete pile. The need for extremely long piles with high bearing capacity led to the use of concrete-filled steel-pipe piles about 50 to 60 years ago.

Driving Stresses in Prestressed Concrete Piles

analysis and design of prestressed concrete piles. The magnitude of the dynamic tensile stresses in prestressed concrete piles is extremely important since these piles are vulnerable to cracking during driving. Such piles are frequently dosignodon the basis of handling stresses only, but 8

PRESTRESSED CONCRETE PILES - Semantic Scholar

Prestressed concrete cylinder piles (Fig. 1) may be used effectively as structural columns and pier shafts. They may be set in pre-drilled holes and then seated by driving or by means of a concrete plug. Prestressed concrete piles are being increasingly used to resist uplift (tension), bend-ing and dynamic loads. They are act-

Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during its fabrication, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in ...
