Sprayed Concrete Essentials

Alkali-free Accelerators

Speeds up concrete setting time. Safer to handle and reduced impact on final strength and durability versus standard accelerators.

Superplasticisers

A range of superplasticisers that deliver high water reduction, high flowability, high durability, easier placement, slump protection and a superior finish.

Hydration Control Admixtures

The TamCem range of Hydration Control Admixtures are designed to extend the time that concrete is workable.

Fibre Reinforcement

A range of synthetic macro concrete reinforcing fibres designed for demanding applications such as mining, tunnelling, decks, highways and industrial floor.

Sprayed Concrete Application Aids

Protective Agents & Cleaners

Non-toxic and environmentally friendly concrete cleaners and protective agents designed to reduce concrete buildup and remove hardened concrete from equipment.

Pump Line Lubricant

Pump and concrete delivery line primer providing lubrication to assist the delivery of concrete to the nozzle.

Dry Spray Mortars

Specially formulated cement based, pre-bagged, gunite mix for dry spray application. Suitable for structural and non-structural repairs.

High Performance Concrete Admixtures

Concrete Improvers

Various types of liquid admixture that can be added to concrete to improve the properties or performance of concrete.

Concrete Bonding Agent

Concrete bonding agents improve the bond between the sprayed concrete layers and/or the substrate and which reduce the evaporation of water from sprayed concrete. TamCem iBond is specially designed for wet-mix sprayed concrete and is EN compliant for bond improving admixtures.

Air Entraining Admixtures

TamCem air entraining admixtures provide enhanced durability and freeze/thaw protection. Normet’s TamCem admixtures are designed for tunnelling and mining.

Sprayed Concrete Equipment with Normet Chemical Solutions

High Strength Concrete Admixtures

A range of high performance shotcrete and sprayed concrete additives to increase durability, early age strength and reduce evaporation in CEM 1 and 2 cements.
