Yield per 25 Kg : 12.5 lit.. approx : Pourable Life : 20 minutes : Application temp. : 10oC to 40oC; Expansion (% Vol): 0.8 to 1.5%. Flow : 20 to 25 cm on flow table. 315% at flow consistency.

Instruction For Use :
 
Mixing :

(1) Place 80% of the water required in a concrete mixer [100% in case of a grout mixer].
(2) Slowly add the required amount of K-5 STONEHARD 60 while continuously stirring for 1 minute. Add balance quantity of water (20%) and mix for 3 to 5 minutes. The mixed grout must be placed immediately and grouting must be continue till the cavity is filled.
 
Surface Preparation :

(1) All contaminated surfaces must be cleaned thoroughly by chemical or mechanical methods.
(2) All bolt pockets and under bases must be free from dust, laitance and of sound substrate.
If needed, substrate with water to allow for full absorption for atleast 24 hours. Just before the grouting is to commence, all water must be removed completely leaving the surface only damp.

Bolt Pockets :

Depending
on the size of the bolt pockets, 50-100% cleaned 10mm sound aggregates by weight of grout consumption may be incorporated to economies on grout and also to keep the heat of hydration low. When the thickness exceeds 100mm-150mm our technical department may be contacted for advise. There must be atleast 12 hours gap between bolt pocket and under base plate grouting sequence. Mechanical mixing using a grout mixer or freefall concrete mixer is recommended. No hand mixing is permitted.



Concrete Admixtures

K CRETE SPDESCRIPTION K CRETE SP is supplied as brown liquid based on sulphonated Napthalene for formaldehyde condensates. The powerful dispering action of superplasticiser can be used in many ways to obtain dense, high strength durable concrete (M350, M400 and M450). The high water reduction upto 30% make K CRETE SP ideal for use in precast concrete where high early strength are of paramount importance. K CRETE SP is chloride free.
 
Increased Work Ability :

K CRETE SP
when incorporated in concrete mixes increases the workability without addition of water thus leading to easy placement and finishing without the risk of segregation and bleeding.
 
Increased Strength
:

K CRETE SP can be used to reduce
upto 30% water for a given workability leading to increase in early and ultimate strengths. Such high early strengths and early stripping of form work lead to increased productivity on precast concrete and the production of high strength concrete without increasing cement content.
 
Advantages :

  • Use in precast concrete work
  • Increased strength 0- high early and ultimate strength, if water reduction is taken advantage of
  • Safe in prestressed concrete improves cohesion thus aids pumping of concrete
  • Facilitates rapid placing of concrete and with little or no vibration
  • Makes the concrete denser, hence durability increased
  • High water reductions upto 30%
 
Purpose :

To produce high strength concrete and flowing concrete without addition of water. Enables high water reduction upto 30% leading to high early and ultimate strength . Ideal in precast concrete works.
 
Product :

To produce high strength concrete and flowing concrete without addition of water. Enables high water reduction upto 30% leading to high early and ultimate strength. Ideal in precast concrete works.

Dosage & Packing :

  • 0.300 6 ltrs/50kg cement. However, the optimum dosage to be determined by site trials.
  • 5,50,100,200litre carbuoys and drums.

Typical Properties
:

Physical state: Brown liquid, specific gravity:1.16 at 27oC, Chloride content: Nil as per IS 456 and BS 5075Air entrainment: Less than 1%additional air entrained.

K CRETE SP can be used in mortar qrouting of prestressed wires
. The normal dosage is 0.30-0.6 ltrs per 50kg cement. However, higher dosages can be used upto 0.8 litres with suitable changes in the mix especially sand to avoid segregation if no water reduction is made.Over dosing upto double the normal dosage levels may lead to retardation of settings times and may tend to segregrate and produce ultra fluid concrete.
 
Handling Precautions :

K CRETE SP is non toxic. However, splashed on the skin should be washed well water and if contact with eye occurs, wash well with water and seek medical advice.
 
Storage Life :

Minimum one year if stored below 50oC in original sealed containers. If allowed to stand sound for a long time, container should be stirred well before use.

Industrial Flooring System
Industrial Flooring System

K5 STONE HARD is designed to ensure improved durability in applications where the floor is subjected to medium and heavy traffic and where a non-dusting surface is required. It will improve and enhance performance of all concrete floors.

Typical Application
:

  • Workshops
  • Power stations
  • Garages
  • Car parks
  • Warehouses
  • Loading bays
  • Factories
  • Shipyards
  • Aircraft hangars
  • Traffic decking
  • Car washes
  • Helicopter pads

Advantages :

  • Quick application and finishing results in considerable time savings.
  • Ease of application
  • Slip-resistant finish can be obtained
  • For internal and external use.
  • Wear, abrasion and impact resistance are superior to normal concrete.
  • High impermeability compared to concrete under the same conditions.
  • Monolithic bond with the base concrete.
  • Non dusty and easy cleaning
  • Economical installation.
  • Maintenance free, ling life performance.
  • Non metallic and iron free does not rust.

Abrasion Resistance
:

K-5 STONE HARD has been tested with FUNDITOR ABRASION MACHINE using Silicon Carbide Wheels
. The sample was tested for 10,000 revs. at a fixed speed and the amount of wear assessed by measuring the depth of the groove by abrasion wheels at four points around the perimeter. The results shows that K-5 STONE HARD improves the abrasion resistance compared to grano by over 200%.

Compressive Strength
:

The K-5 STONE HARD cubes when tested for compressive strength have typical strength of over 800 kg/cm2 at 28 days. Mho’s scale hardness between 8 to 9 scale.
      
Application Instructions :

Base Concrete:

The base concrete
should have a minimum cement content of 300 kg/m3 with low slump of 40-60mm. To improve the quality of concrete mixes and enable low w/c ratio to be kept, K-CRETE N normal plasticizer may be used at a dosage rate of 150-200ml/50kg of cement.

Method Of Laying Base Concrete :

The base concrete must be laid in accordance with good concrete practice either in bays or long strips. Particular care must be taken at the corners and edges of the bays to obtain good compaction and to maintain level for subsequent trowel operations. If too much of free water is seen on the surface, water content in subsequent concrete must be reduced to obviate the presence of free water.

The time of the application is very important in order to derive full benefits of k-5 stone hard. if k-5 stone hard is applied too early, it will absorb water hard wearing aggregate may sink to the bottom. If application of K-5 STONE HARD is delayed, no moisture from the concrete surface will be available to hydrate K-5 STONE HARD, resulting in poor pitted surface.
