SILICO Crete is a single component polymerised cement based mortar formulated for restoration/repairing of all types of RCC members like Beam, Column, Slabs etc. It is non-pourable high strength dual shrinkage compensated repair mortar with fibre reinforcement specially formulated for repairs and restoration of damaged or weakened structural concrete members.
It is specially designed to be used in those places where shuttering cannot be done. SILICO Crete is manufactured by select ingredients, controlled proportioning of performance enhancing admixtures together with best possible blending. The performance enhancing additives along with fibres provide controlled expansion characteristics in the plastic as well as hardened state, reducing crack formation and minimize water demand.

- Single component - Mix is ready by just addition of water (“Just Add Water” System).
- Fibre Reinforced for additional toughness, ductility and tight crack control.
- Dual Shrinkage Compensated to reduce the risk of cracking.
- Eliminates manual batching, weighing, proportioning and dosing of cement, sand and liquid polymer on site.
- Economical pre-packaged repair mortar offers more consistent proportioning and performance than site-mixed mortars. The resultant is a high-strength repair compound offering exceptional workability, durability and productivity.
- Supplied in premixed, preweighed, prepacked condition.
- Can be applied by hand like conventional polymer mortars or trowel-applied.

- 1. Surface preparation:
Surface preparation must result in the removal of all unsound concrete and all contamination which hinders adhesion or performance of SILICO Crete. A clean, hard rough surface should be provided.
Shape and depth of the repair should also be considered. Although SILICO Crete repair compound is designed to adhere and gain strength even in thin sections, many types of structural repairs are better accomplished when edges are saw cut.
- 2. Reinforcement Steel Bars:
Expose fully, any corroded steel in repair and remove all loose scales and corrosion deposits around its full circumference. Steel should be cleaned to achieve a bright condition. Use a Rust Remover as a rust converting primer for rust free rebars. Where the reinforcing bars are corroded, cut back the concrete from the exposed rebar to the extent of at least 20mm behind the reinforcing bar. Remove the corrosion from and around the reinforcing bar. Then this rebar should be coated with anti-corrosion products to protect from corrosion. Replace the affected part of rebar, if the diameter of the rebar, after cleaning is reduced by 18% to 20% of the original diameter of the rebar. Apply two coats of suitable bond coat, taking particular care to follow all the general and specific application guidelines or methods to passivate the steel reinforcement.
- 3. Substrate priming:
Surfaces should be dampened with clean water for at least 20 minutes before patching. Any excess water should be removed before and subsequently primed with suitable bond coat as a bonding agent.
- 4. Mixing:
SILICO Crete is a one component product which needs only addition of water on site. Care should be taken to ensure that SILICO Crete is thoroughly mixed in a forced action mixer. The dry mortar is slowly added to the water and mixed thoroughly until a homogenous mortar is achieved. Slow paddle mixers or drum mixers are suitable in which the mixing should take place for at least 3 minutes, ensuring a smooth homogeneous consistency of the mix. Allow the mix to rest for 2 - 3 minutes and then remix for a minute or two before applying. Hand mixing may be allowed to be performed if the quantity of mortar required is very small but care should be taken to thoroughly mix the mortar into a “dough-like” consistency and mixing should take place for at least 5 minutes.
