Lightweight concrete floor provides more efficient strength to weight ratio in concrete floor systems when compared to other conventional concrete floor systems.
Lightweight concrete roof decking.
Lightweight insulating concrete low density non structural concrete comprised using ultra lightweight expanded mineral aggregates or preformed foam.
The increase can also be attributed to the economic and environmental advantages that lightweight insulating concrete lwic provides in roof assemblies.
Dektek s luxury tile decking is custom poured high strength concrete deck tiles that support more than 1 000 lbs per tile.
Compressive strengths from 125 350 psi are common for lwic used in roof deck.
Dektek tile is an elegant and innovative precast concrete decking material that is especially designed for elevated decks and roof decks.
The addition of insulation board increases r values and reduces dead load.
The concrete deck tiles are 1 thick and weigh approximately 10 5 lbs per.
The lighter the concrete the better lower the k factor.
The use of lightweight concrete as a roof decking and insulation system has expanded in the past five years.
The most common use of vermiculite lightweight concrete is for light structural roof decks and for insulation fill over metal decking and structural concrete.
Lightweight roof deck concrete is a one component lightweight insulating concrete ideal for roof fills and for providing slope.
With standard structural concrete the aggregate used is sand and stone.
With structural lightweight concrete a mix of shale slate slag and clay are used and with this mix the aggregate is fully saturated prior to mixing.
It is adaptable to any roof configuration and depending upon the condition of the existing roof may be installed directly to build up roofs gravel roofs and galvanized steel deck roofs thus eliminating costly tear.
Usg s structural panel concrete roof deck can be applied with mechanical fasteners to serve as a structural substrate for direct mechinically or adhesive applied roof systems.
Vermiculite for roof decks can be placed over various kinds of form boards fiber fiberglass acoustical and asbestos cement.
However when a lightweight structural concrete lwsc roof deck is poured in place it uses significantly more water.
The normal weight concrete employs standard aggregates i e.
Structural panels concrete roof deck is an innovative technology designed to provide a structural roof sheathing without the need for thermal barriers pouring.
Aerix insulating concrete for a superior roof.
Lightweight insulating concrete lwic is defined as having oven dry unit weights of 50 lbs ft or less.
Hard rocks with a low water absorption rate and weighs approximately 2403 kg m 3 150 lb cf.
Aerix insulating concrete provides a superior lightweight concrete roof surface compared to rigid board insulation systems.
Installed over precast cast in place concrete or galvanized steel decking.
Increased usage can be attributed to the recent industry wide insulation shortages and delamination deficiencies.
