SpECtop Armourite Standard

DRY SHAKE, MONOLITHIC SURFACE HARDENER FOR NEW CONCRETE FLOORS

SpECtop Armourite Standard is supplied in 25kg
bags and consists of graded synthetic mineral
aggregate blended with Ordinary Portland cement
and plasticisers.

SpECtop Armourite Standard is applied to
plastic concrete and the resulting finished surface
is extremely dense, abrasion resistant and hard
wearing. As the application of SpECtop Armourite
Standard results in the floor curing monolithically
with the topping, excessive shrinkage, cracking etc.,
is avoided.

The aggregate used, apart from being completely
inert chemically, is exceptionally hard and is not
prone to polishing.

Technical Details

SpECtop Armourite Standard can be used in any application where an uncoated concrete is required to provide high abrasion, skid and impact resistance.

It is particularly suited for heavy industrial wear.
· Non metallic aggregate
· No additions required – ready to use
· Extremely hard wearing aggregate resulting in high resistance to abrasion and impact
· Monolithic bond to host concrete
· Resistant to oils and greases

Typical Values Compressive strength 

 
28 days 

70 N/mm² 

Abrasion Resistance 

Test data indicates that concrete floors treated with SpECtop Armourite Standard exhibit an abrasion resistance 300% better than that exhibited by 40 N/mm² concrete on its own. 
Hardness 

When tested against the Mohs hardness scale, the synthetic aggregate used in SpECtop Armourite Standard provided values in excess of 7.0. 

Impact Resistance 

Testing in accordance with B.S. 8204: Part 1 gave results 3.5 times better than those required of a screed designed to with stand heavy traffic. 

Preparation
It is essential that adequate planning of the application is made in advance and that sufficient material is laid out to meet the requirements of the application.

The base concrete slab should have a thickness not less than 80mm and the concrete mix design should be formulated as follows:
Water/cement ratio      < 0.50
Cement content/m3     > 300kg
Slump     > 75mm
Air entrainment     < 2%
Vacuum dewatering should not be used.

Application
SpECtop Armourite Standard should be applied at the rate of 5 to 7kg/m² depending on the degree of traffic anticipated.
SpECtop Armourite Standard must be applied as soon as the base concrete has reached the stage where light foot pressure leaves an indentation of around 5mm or as soon as it is practicable to apply the product correctly without damaging the plastic surface of the base slab.

On large applications it is essential that sufficient operatives are available to work at a controlled rate behind the concreting team.

SpECtop Armourite Standard is applied in two applications. The first application utilises two thirds of the chosen application rate and is broadcast evenly across the surface but ensuring the material lands nearly vertically rather than spread horizontally. Once applied the free water in the base concrete will slowly darken the applied material and once this stage is complete, wood floating of the surface can commence. Do not over trowel at this stage.

The remaining one third of the material can now be applied and moisture allowed to combine with the material as before and wood floating of the surface can be completed. Once the floor has attained a degree of stiffness at which light foot traffic does not mark the surface, steel floating and/or power floating can progress.
SpECtop Armourite Standard pack in 25kg bags.

Medium duty      5kg/m²
Heavy duty      7kg/m²
