NEODUR HE65
for coating of concrete surfaces
for heavy duty application - with PP-fibres-
DESCRIPTION
NEODUR HE 65 hard aggregate screed is a ready to use cementitious hard aggregate screed on the basis of KORODUR hard aggregates acc. to DIN 1100 - A 0/5, processed as a compound screed in one or two layers for heaviest stress demands, acc. to DIN 18560-7.
The factory admixture of PP-fibres effects a considerable reduction of possible crack formation.
NEODUR HE 65 is also available in colours, see our KORODUR colour chart.
APPLICATION
For the production of heavy duty industrial screeds, e.g. in production halls, workshops, high-shelf-stores and other industrial surfaces exposed to heaviest stress.
PROPERTIES
- resistant against gasoline, mineral oil, solvents
- highly wear resistant also under most severe stress
- fork-lift truck resistant
- waterproof, qualified for wet rooms
- anti-skid/non-slip
- frost and de-icer resistant
- electrostatic non-chargeable
- chloride-free
- physiological harmless
- high surface density
- uniform quality due to outside and factory control acc. to EN 13813 ®
PROCESSING
Fresh-on-fresh processing:
The base concrete must be produced min. as C 25/30 acc. to EN 206. The use of the KORODUR plasticizer KOROPLAST is recommended. The surface must be produced in level within the tolerance limit acc. to DIN 18202. The fresh, just walkable base concrete is planed with a disk float. NEODUR HE 65 is mixed in the pan type mixer with water (W/F = water/material value = 0,10-0,12) depending on installation method - mixing time approx. 3 minutes - and installed. NEODUR HE 65 is levelled off over gauges (iron rod) with aluminium lath or vibrating beam and intensively smoothed on time.
On hardened base concrete:
The existing base concrete, strength class min. C 25/30, must be pretreated by milling, shot peening. For permabond compound the surface must be free from cracks, even, free from loose and brittle particles and cement laitance, rough and open-pore. The evenness should be acc. to DIN 18202, table 3, line 3. The prepared base concrete to be pre-wetted 1 day prior to the installation, avoiding formation of puddles. On the matt-damp surface the KORODUR Bonding Compound HB 5 is applied, see technical data sheet. The installation of NEODUR HE 65 takes place analogous to the processing instructions for „fresh-onfresh", whereby in this case the installation can be carried out almost jointless.
AFTER-TREATMENT
Differing temperatures may influence the setting and hardening procedure. The NEODUR hard aggregate screed must be protected from too rapid drying out acc. to DIN 1045-3.
We recommend for curing KOROTEX or KOROSEAL (see technical data sheets).
