a.b.e. Construction Chemicals has expanded its range of dustless cementitious products with the launch of a dustless version of abe.dur – the company’s popular non-metallic high-strength floor screed.

a.b.e. is part of the Chryso Southern Africa Group of companies.

For the first time abe.dur is available in a dustless format, and also in a single-pack formulation which eliminates mixing the product with ordinary portland cement (OPC) and therefore the possibility that using sub-standard OPC will negatively affect the screed’s performance.

Peter Jones, a.b.e.’s national sales manager: flooring, says the new product, abe.dur S – Dustless, is a blend of exceptionally hard, high wearing natural aggregates, shrinkage-compensated cement – free from any metallic material – ideal to produce a durable granolithic type of floor.

“abe.dur S Dustless is suitable for both interior or outdoor flooring surfaces that experience heavy wear and operate in very wet or dry situations. Screeds produced with abe.dur S Dustless can be applied to fine tolerances with respect to line and level.

abe.dur has been successfully used in mine stores and changerooms, hostel kitchens, abattoirs, warehouses, bakeries, fish shops and shopping malls. It is also suitable for sand blasting plants, pavements, bus sheds, drying tunnels, and freezer rooms.

The new dustless version will be welcomed by a construction industry increasingly obliged to meet more stringent ‘green’ operating conditions. The fact that the product is now also pre-mixed will also provide more assurance of consistent quality to contractors,” Jones feels.

Advantages of abe.dur S Dustless include:

* Ease of application: needs only the addition of potable water to form the mix;

* Scope for selecting specific surface profile finishes;

* Ultra-high strength and abrasion resistance;

* Quick turn-around;

* Uniform application thicknesses of between 10mm and 35mm; and

* Can be monolithically applied on top of a new ‘green’ subfloor.

Jones says when abe.dur S Dustless is laid monolithically on concrete, the slab should be cast to within at least 10mm of the finished level after the concrete had attained initial setting. “When the product is bonded to an existing floor with an epoxy adhesive, such as a.b.e.’s epidermix 116, the floor should have suitable compressive and tensile adhesion strengths.”

He adds that full curing is essential and – if properly carried out – could lead to abe.dur S Dustless achieving compressive strengths of over 80 MPa.
