Structural Model for FibreReinforced Precast Concrete

Precast/Prestressed Concrete: Model for Concrete Confined

It is also desirable for the concrete to have greater ductility, and to this end, it has been suggested that spirals of reinforcement should be included in the compression zone (with their axes aligned parallel to the compressive force) to provide additional confinement; if fibre reinforced plastics (FRPs) are being used as the tension reinforcement it is logical to use them also for the hoop

Design according to MC of a fibre‐reinforced concrete

This paper discusses the possibility of using precast tunnel segments in fibre‐reinforced concrete without traditional reinforcement. The case study of a hydraulic tunnel in Monte Lirio, Panama, excavated with a tunnel boring machine (TBM) by SELI S.p.A., has been analysed. The segments were designed according to the draft of Model Code 2010.

Understanding the Difference between Cast Stone and

While it can be substituted in for precast concrete in situations where it is specified as minimally load-bearing and non-structural, that is not the case when precast concrete is structural. Also, cast stone is a division 4 masonry material. Therefore, the connection methods and sizes need to be within the scope of the masonry contractor's work.

Research on the Design Method of a Scale Model of ECC

Engineered cementitious composite (ECC) is a class of high performance cementitious composites with pseudo strain hardening behavior and excellent crack control. Substitution of concrete with ECC can avoid the cracking and durability problems associated with brittleness of concrete. In this paper, it is aimed to design a scale model of ECC reinforced concrete precast shear wall structure.

Concrete Reinforcing Fibers - Sika

Fiber reinforced concrete is a composite material and therefore, all fibers are tested in the concrete to prove their performance. Fibers begin to function in a structural supportive manner when the concrete matrix starts to crack, just like traditional reinforcement. The crack has to occur for the load to switch from the concrete to the

What is Lightweight Concrete? -Types, Uses and Advantages

Aerated concrete is a lightweight, cellular material consisting of cement and/or lime and sand or other silicious material. It is made by either a physical or a chemical process during which either air or gas is introduced into a slurry, which generally contains no coarse material. Aerated concrete used as a structural material is usually high
