STRUCTURAL CONCRETE SINTAGG LDA LOW DENSITY AGGREGATES

SINTAGG LDA  lightweight aggregate is up to 50% lighter than normal weight aggregate

WEIGHT

SINTAGG LDA lightweight aggregate is up to 50% lighter than normal weight aggregate

Using SINTAGG LDA coarse aggregates reduces the weight of structural concrete by around 25% compared with natural aggregate concrete.fine aggregate allows further weight reductions of up to 40%.

Advantages : Less concrete and steel used; dead load of structure reduced; less foundations needed.

Benefits : Significant cost savings.

STRUCTURAL PERFORMANCE

AS STRONG AS NORMAL WEIGHT CONCRETE

image

SINTAGG LDA lightweight aggregate concrete can provide the same level of structural performance as normal weight concrete so it can be used in exactly the same way.

compressive strength of up to 65N can be achieved.

Advantages : Meets IS CODE 9142 - PART2 Standards at a fraction of the weight. 

Benefits : Same performance as natural aggregate concrete; reduced costs; greater design flexibility.

SAVINGS

SUBSTANTIAL SAVINGS

image

Because SINTAGG LDA concrete is significantly lighter with no loss in strength over natural aggregate concrete, it reduces the dead load of the building. Substantial savings are made in concrete, reinforcement, foundations, CO2e, haulage, time, and associated construction costs. See the independent study.

Advantages : Savings of up to 48% in foundations. 10mm saving on the depth of floor slabs 10% less CO2e.

Benefits : A cheaper, quicker and greener building.

Savings can be made in many elements of haulage, including transporting raw SINTAGG LDA  in place of natural aggregate, and concrete and reinforcement deliveries.

See the independent study.

Advantages : Quicker and cheaper delivery.

Benefits : Savings in time and haulage costs; Significant savings in CO2e.

INSTALLATION

AS EASY TO PLACE AS NORMAL WEIGHT CONCRETE

image

Placing and compaction is as easy as with normal weight concrete. SINTAGG LDA  concrete can be pumped long distances and to great heights, as proven by its use in numerous recent structures such as the Shard and 20 Fenchurch St (the Walkie Talkie). Finishing processes used for normal concrete can easily be applied to SINTAGG LDA  concrete.

Advantages : No specialist skills or tools needed. All possible concrete finishes can be achieved. High flow values achievable aiding speed of placement and workability.

Benefits : No extra cost for normal installations.

THERMAL EXPANSION

NEEDS LESS MOVEMENT JOINTS

image

Using SINTAGG LDA  reduces the coefficient of thermal expansion by 33% over normal weight concrete.

Advantages : Less movement joints are required. Reduction in risk of thermal cracking.

Benefits: Cost reductions; design benefits.

INSULATION

100% IMPROVEMENT IN THERMAL CONDUCTIVITY

image

Using SINTAGG LDA not only reduces the density of your concrete but also improves the insulating properties with double the thermal performance of normal weight concrete. It meets all rating requirements.

See the independent study.

Advantages: Reduced value leading to improved U value of elements within the structure.

Benefits: More thermally efficient structures; reduction in cold bridging.

FIRE RESISTANT

CARRY TWICE THE VOLUME PER TRUCK

image

SINTAGG LDA pellets experience extreme temperatures during manufacture. As a result they are more stable at high temperatures, have a lower expansion coefficient, and a lower reduction in strength. This makes SINTAGG LDA  ideal for fire resistant applications such as lift shafts and tunnels.

Advantages : Meet all ratings at a reduced cost.

Benefits : Increased overall fire safety of structures.

DESIGN

GREATER DESIGN OPPORTUNITIES

image

SINTAGG LDA allows architects and structural engineers to push the boundaries of design by including longer cantilevers, slimmer general sections, larger spans and fewer or smaller columns.

Advantages : Less constraints on design; larger floor spaces.

Benefits : More available space for the client to utilise; architects and engineers can gain a competitive advantage at the tender stage.
