6. Prestressed Concrete: It is a special type of reinforced concrete in which the reinforcement bars are tensioned before being eedded in the concrete. Such tensioned wires are held firm at each end while the concrete mix is placed. The result is that when the
Mastied Rubber Hanna Rubber Company produces Mastied (recycled) Rubber Load Bearing Pads, which are used in many construction appliions such as precast and prestressed concrete bridges, building and structural steel bearing appliions, as well as machinery, equipment foundation, railway tie pads, and shock and vibration isolation.

Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures.They stop the bridge from
being very inconvenient to the traveling public. Bridge structures are expected to last at least 75 years and preferably 100 years. Therefore, it is critical that the reinforced concrete piles be designed with materials that resist corrosion or are corrosion free so that

The necessity of taking into account the compliance of rubber-metal supporting parts in spatial dynamic calculation scheme for bridges with prestressed concrete spans is substantiated. The finite element model of rub-ber-metal supporting parts is described.
There are wide varieties of rubber products used in the rubber industry. First of all rubber tires and rubber tracks are the most commonly used rubber products in the construction industry. The excavators, the cranes, fork lifts, concrete mixer machines, erpillar, lift truck etc. used in various construction purposes are all fitted with tires and tracks made of rubber.
To achieve optimal loading in a straight rubber hose the fibres must be positioned under an angle of approximately 54.7 angular degrees, also referred to as the magic angle. The magic angle of 54.7 exactly balances the internal-pressure-induced longitudinal stress and the hoop (circumferential) stress, as observed in most biological pressurized fiber-wound cylinders, like arteries.
The ContiTech Allcrete hose is for use in plaster & grout, shotcrete appliions, and handling a multitude of materials being pumped to concrete structures, dams, tunnel faces, swimming pools, etc. The ContiTech Allcrete hose maintains a temperature range of -25˚F to 180˚F (-32˚C to 82˚C) and is ideal for handling large concrete jobs.
