CONPATCH
HPM
A High Strength Cementitious, Free Flow, Repair concrete
Introduction
CONPATCH
HPM is a specially prepared Prepacked, flowing micro concrete which
requires addition of water only at site to produce free flow high
strength shrikage-compensating concrete. It has micro fine-aggregates
and ablility to penetrate in joint to the recesses of concrete membrane
and behind the reinforcement of the membrane under repair for larger
repairs the mixed product may be modified by the addition of 12
mm down aggregates at site. CONPATCH HPM is a blend of selected
portland cement, specially well-graded micro fine aggregates expansion
agent and a range of fluidifiers. CONPATCH HPM is ideally suited
as a repair concrete for Structures, Highway Works, Beams, Columns
etc.

8. Chloride free
9. Prepacked and factory controlled
10. High-tensile and flexural strength
11. Reduced co-efficient of creep
STANDARD GUIDELINES: ACI 302, 303
YEILD: A 25 kg. of CONPATCH HPM when mixed with 4.5 litre
of water, will yeild approximately 12 litre of repair concrete.
PACKING: 25 kg, 50 kg. bags.
PROPERTIES
CONPATCH HPM has 3 beneficial properties
| 1. |
Free
flow : CONPATCH HPM when mixed with recommanded W/P ratio,
a cohesive fluid, mix is obtained which can be easily poured
in congested reinforced concrete, under repair or where pouring
is difficult. |
| 2. |
High
Strength :CONPATCH HPM exibits rapid strength development
ultimate strength is more than 560 kg/cm2 |
| 3. |
Expansivity
: Positive expansion during setting leads to superior bonding
to surrounding materials. |
AREAS
OF USAGE:
All structure under repair. It may be used in any application requiring
an Economical, High-strength, Free flowing repair concrete.

METHOD
OF USE
1. Preparation :
The substrate should be sound, clean and free from contamination,
weal portion of concrete should be cut back and roughened
carefully prewetted. Formwork must be sound to eliminate leakage.
2. Application : CONPATCH HPM should be mixed with correct amount of
clean water preferably by mechanical means to get desired consistency
and pour in the forms. The powder should never be poured in to still
water. Care should be taken to see that the gaps in the shutter
are effectively sealed with masking tape or cotton to ensure that
the matcrial doesn't run out of shutter joints
3. Curing : All standard curing practices should be observed sacks,
matting, plastic sheets or a curing compound may be used for curing
purpose.
SHELF
LIFE: CONPATCH HPM has a shelf life of 12 months if un-opened. Protect
from moisture.
HEALTH
& SAFETY: CONPATCH HPM is mildly alkaline. Prolonged contact
with skin should be avoided.
