Curing Compound

Description

A curing compound based on aluminized synthetic resin for the prevention of premature water loss from concrete. It is in ready to use and simple to use.

Uses

ADDCURE is sprayed on to newly laid concrete surfaces to form a thin film barrier against premature water loss. Without disturbance to the normal setting action the concrete is then allowed to cure and achieve maximum properties. ADDCURE is particularly useful in large areas of exposed concrete like highways, runways and roof decks, retaining walls, canals etc.

Advantages

ADDCURE provides the following beneficial properties to concrete surfaces:

• Ensures achievement of desired strengths
• Minimizes shrinkage
• Reduces dusting
• Increases frost resistance
• Alleviates other costly methods such as hessian-watering, etc.

Coverage

0.15 to 0.20 kg/sq. mtr. depending on wind, humidity and temperature.

Instructions for use

ADDCURE has been designed for spray application to the newly laid concrete once the surface water has evaporated. A thin layer of ADDCURE is then applied to the whole surface using a hand operated spray gun. For large areas
application can be done by power driven automatic equipment. Stir well before use. After application the area concerned must be protected from rain for at least 2-3 hours.

Cleaning

Clean all tools and equipment with petrol.

Handling Precautions

ADDCON Products are generally quite harmless, provided certain precautions are taken for handling chemicals. Avoid contact with foodstuff and food utensils. Avoid prolonged skin contact. Wear protective clothing, gloves etc. (barrier cream). In the event of contamination, wash thoroughly with water. If the eye or mouth is affected, wash with clean water immediately and obtain medical attention.

Hard Aggregates for Floor – Surfacing

Description

A cementitious ready mix compound with very hard granulated of predetermined granular size containing carborandum to generate hard cementitious floor top. The hardening compounds are selected for their physico – chemical qualities.
Available in Grey colour.

Uses

It is used as an economical and ready to use component for making hard floor surfaces suitable for warehouses, quays, circulation lanes. It is suitable for :

• Small mechanical engineering workshops
• Precision engineering workshops
• Parking lots, service stations, garages, etc.

Advantages

It provides the following beneficial properties :

• Increase resistance to abrasion
• Resistant to mechanical wear
• Can be applied easily on freshly laid floor surfaces and slabs.

Coverage

• Approx. 3.5 to 6.0 kgs. per M² area for a thickness of 2-3 mm surfacing.
• For Light duty 3.5 to 4.0 kgs. / M²
• For Medium duty 4.5 to 5.0 kgs / M²
• For Heavy duty 5.5 to 6.0 kgs / M²

Preparation of Substrate

The grade of concrete for substrate should be preferably M20. At the time of construction of floor, as soon as the plasticity of the mix is reached, smooth out the surface of the freshly poured concrete and flatten off with the vibrating straight edge. this concrete should be dense and compact which could be obtained by adding ADDCONplast Super (0.3 % by weight of cement). It is preferable to use a mechanical trowel for smoothing operation.

Spreading and Flattening out

The ready mix ADDCON Hardtop compound will be spread over the newly laid smooth concrete surface at a stage when a nail mark of 3-4 mm will be obtain at standard pressure. The spreading is done by hand or with a suitable apparatus at the rate of Approx. 4.5 to 6.0 kg. per M² of slab area. Wait till the mixture has been uniformly moistened by the surface water contained in the green concrete. Smooth out with the mechanical trowel which should be maintained perfectly flat, operating at a low speed.

Smoothing out

The final smoothing, if necessary, should be carried out sometime later with the mechanical trowel by operating at a low speed.

Curing

Immediately after the flooring surface is finished, it should be protected from rapid drying. As soon as the surface is hardened sufficiently, to prevent damages to it, the same should be kept continuously moist for atleast 3 days by means of wet gunny bags or pooling water on the surface. During this period the flooring should not be exposed to any traffic.

Important Recommendations

The joints of shrinkage and insulation, notably around pillars, shall be formed about every 4 to 5 m in both directions. one must take into account the existing joints already in the base preparation and for the alignment of pillars and circulation lanes. The above joints should be cut into about 1/3 of the thickness of the slab.
Greater thickness of hard surface may be achieved by spreading more compound on the green concrete.
According to the ambient temperature and the kind of cement used in the slab, the pre – usage waiting time is :

• 48 to 72 hours for pedestrian traffic
• 7 to 10 days for light traffic vehicles
• 28 days for normal traffic
