applicable to hollow core slabs by entering the graph with the equivalent thickness of the unit instead of the thickness. equivalent thickness can be calculated by dividing the net area of the cross section of a hollow core unit by the width of the unit. in figure 6.2, concrete aggregates are designated as lightweight, sand-lightweight,

the sound of silence. hollowcore also benefits the residents or tenants of your buildings. the mass effect of our concrete creates a pleasant living or productive working environment, eliminating unwanted sound or vibration. even more, the effect will maximize the efficiency of your heating and cooling systems.

1. equivalent concrete thickness. all wells hollowcore sections are made with a siliceous concrete type. this value can be found in the table above under equivalent thickness. equivalent thicknesses can be calculated by dividing the cross-sectional area by the nominal plank width 48 .

an excellent building material. serving as a combined deck and ceiling system, the planks erect quickly to reduce on-site labor needs and are capable of spanning long open spaces to aid design flexibility. continuous, interior voids add structural stability, reduce weight and, therefore, reduce cost.
hollowcore gets its name from the hollow cores running through the length of the slabs where concrete has limited structural value. this helps to reduce the weight and when combined with pre-tensioned reinforcing, leads to maximizing the span and strength while minimizing the depth.

hollow core plank, prestressed hollow core slab, precast concrete, mid south prestress. using an extruded process, hollow core plank or hollow core slab is a plant manufactured prestressed concrete slab with continuous cores, or voids, which considerably reduces weight up to 50% compared with a poured in place flat slab and cost.
in most cases, the slabs are cast on long line beds, normally 300 ft to 600 ft long. slabs are then sawcut to the appropriate length for the intended project. the economy of the generalized hollow core system is in the quantity of slabs that can be pro- ducedatagiventimewithaminimumoflaborre- quired.
