Product Description

Uses:-

For repairs to damaged reinforced concrete elements, particularly where access is restricted and where vibration of the placed material is difficult or impossible. Suitable for various structural strengthening measures such as encasement buildups, etc.

Advantages:-

Gaseous expansion system compensates for shrinkage and settlement in the plastic state.
Can be pumped or poured into restricted locations.
Highly fluid to allow for placement without vibration.
Pre-packed to overcome site-batched variations.
Rapid strength gain to facilitate early reinstatement
High ultimate strengths and low permeability of cured repair.
Contains no chloride admixture.

Design criteria:-

Renderoc RG(S) can be applied in sections upto 100mm deep. For larger sections, the addition of approved aggregates may will depend on the specific configuration of the repair location. Consult the local Fosrocoffice for further information.

Specification clauses:-

The fluid micro-concrete repair material shall be RenderocRG(S), a single component, cement-based, micro-concrete to which only the site-addition of clean water (and approve d graded coarse aggregates where specified) shall be permitted

The micro-concrete shall contain no metallic aggregates, orchlorides and shall be shrinkage compensated in the plastic state. The micro concrete in the flowable consistency should achieve a compressive strength of not less than 10N/mm2 after 24 hours at 300C. Most importantly, the cured microconcrete shall have a coefficient of thermal expansion similar to that of the host concrete

Application instructions:-

Preparation:-

The unrestrained surface area of the repair must be kept to a minimum. The formwok should include drainage outlets for pre-soaking and, if beneath a soffit, provision for air venting. Provision must also be made for suitable access points to pour pump the mixed micro-concrete in place.

Defective concrete surfaces must be cut back to a sound base.Smooth surfaces should be mechanically roughened. Corroded reinforcing steel should be exposed around its full circumference and cleaned to remove all loose scale and corrosion deposits. It is important to clean the steel to a bright condition. Grit-blasting is recommended

One coat of Nitozinc Primer should be applied on the reinforcing steel. If any discontinuity in the applied film is noticed, onemore coat has to be applied.

Several hours prior to placing, the concrete substrates should be saturated with clean water. Immediately prior to placing, any free water should be removed. Alternatively, all prepared concrete substrates should be primed using Nitobond EP, a slow – setting epoxy bond aid. Nitobond EP shall be applied only on dry substrate.

Note : For repair sections generally deeper than 100mm it may be necessary to mix the Renderoc RG(S) with properly graded 5mm to 12mm silt-free aggregate to minimise temperature rise. The quantity of aggregate required may vary depending on the nature and configuration of the repair location. The typical results with a few aggregate proportions, for various applications are furnished below for guidelines

Mixing:-

Care should be taken to ensure that Renderoc RG(S) is thoroughly mixed in a forced-action mixer of adequate capacity. Alternatively, mix in a suitably sized drum with a high torque (400/500 rpm) rotary drill fitted with a mixing paddle.

It is essential that machine mixing capacity and labour availability is adequate to enable the placing operation to be carried out continuously. The quantity water required will generally be between 4.5 and 4.75 litres per 25 kg bag of Renderoc RG(S). The optimum water content should be determined and accurately measured into the mixer.However it should not exceed

4.75 litres / 25 kg in any case.With the mixer running, slowly empty Renderoc RG(S) bag into the mixer. Mix continuously for 5 minutes, ensuring a smooth even consistency of the mix.

Where the addition of graded coarse aggregate has been specified it should be added after the water and Renderoc RG(S) are properly mixed. Mixing should then continue for a further 1 minute to ensure proper dispersion.

Form Work:-

Slurry tight form work that will not deform or leak when subjected to hydraulic pressure imposed by the microconcrete will be fabricated and erected where the material is gravity fed. Provision in the formwork will be made for a suitable feed hopper at the highest point. Where necessary, provision will be made for air vents to prevent air entrapment. Form work will be coated with Reebol mould releasing agent prior to fixing.

Placing:-

The mixed material should be placed immediately. If placed by pump, standard concrete pumping practice should be followed. The pump and pipeline must be primed with cement slurry. Pumping should be commenced immediately after priming. If poured in the form work, avoid air entrapment by pouring from one side only.

Low temperature working:-

In cold conditions down to 150C, the use of warm water (upto 300C) is advisable to accelerate strength development. Normal precautions for working with cementitious materials in winter should be adopted

High temperature working-

At ambient temperature above 350C the material should be stored in the shade and cold water used for mixing

Curing:-

As Renderoc RG(S) is a cement-based repair material, it must be cured immediately after stripping the formwork in accordance with good concrete practice. The use of Nitobond AR or any of Fosroc’s Concure range of curing compounds, sprayed on the surface of the Renderoc RG(S) in a continuous film, is recommended soon after stripping the form work. In harsh drying conditions, supplementary curing such a wet hessian and/or polythene sheeting must be used.
