General Introduction: Precast Hollow Core slabs are pre-stressed concrete elements with continuous voids to reduce weight and cost hence capitulate an efficient structural system. Slabs are casted with advanced extrusion technique and can be used as flooring and roofing systems. Hollow Core slab is one of the numerous quality products in which

The extruder produces the hollow core slab using the extrusion method (no vibration needed), it can be used on all common production beds. The standard width of the hollow core slab is 1200 and the height is from 150-500 mm. The extruder is equipped with a cable drum. If you want to receive more information, please contact us.

Precast concrete is a highly versatile construction material that offers impressive design flexibility, energy efficiency, rapid installation and cost savings, among other notable benefits. New admixtures, concrete mixtures, fabrication techniques, and other innovations continue to change and expand the applications of the material and its

METRIC Concrete Industries was formed in 1996 and has quickly established to become a leading producer of highly engineered precast reinforced concrete (RC) and prestressed (PC) piling solutions. Our products include RC square piles, pre-stressed RC piles, pre-stressed hollow core slabs, and precast wall panels.

HOLLOW CORE SLABS SECOND EDITION by Donald R. Buettner and Roger J. Becker Computerized Structural Design, S.C. Prepared for the PCI Hollow Core Slab Producers Committee John E.

Hollow core slab (HCS) is a concrete slab provided to lessen weight and, consequently, cost and, as a part advantage, to use for hid electrical or mechanical runs. Fundamentally used as roof or floor deck systems. Hollow core slab likewise have applications as bridge deck units and spandrel members.

This is possible with automation. The biggest effect on the compaction efficiency in hollow-core slab production is formed by the structure of the extruder and the compaction mechanism. "Often concrete casting is a bottleneck for the efficiency of precast material production, especially hollow-core slabs.

concrete hollow-core slabs.14-16 Most of the aforementioned fire tests were performed un-der standard fire exposure solely to develop fire-resistance ratings for tested precast, prestressed concrete hollow-core slabs, or test data were used to extrapolate fire-resistance ratings for similar hollow-core slab configurations. Based

Elematic’s hollow core floor production equipment is the mainstay of the Fritz-Alder plant expansion. The Extruder E9-1200e utilizes shear compaction that adjusts to concrete properties. The floor production line also includes six 320-ft. beds, a Lifting Beam E9-10-16, and a Saw S5-400. With the new system, Fritz-Alder is able to produce

Flat Roofs: Hollow-core Concrete Slabs. Paroc Air is a simple and safe solution for making dry flat roofs. PAROC Air keeps the roof structure dry without any mechanical systems. The basis for this simple but effective solution is natural air pressure. Effective roof insulation has three or four insulation layers.
