Cebex 100 is supplied as a powder admixture. The material is a combination of a plasticising agent and a gas-producing expansion medium. The plasticising agent allows the use of a reduced water/cement ratio with consequent increased strength and durability. The expansive medium counteracts the natural settlement and plastic shrinkage of the grout and aids stability and cohesion. Sufficient restrained expansion is developed to ensure a high degree of interfacial contact.

Pumping Aid is a universal concrete admixture to improve difficult concrete mixes and to protect concrete pumps and pipes from excessive material wear.

Pumping Aid is a universal concrete admixture to improve the pumpability of difficult concrete mixes and protect concrete pumps and pipes from excessive wear.

Reebol Emulsion Xtra is supplied as a pale amber liquid which turns emulsifi er when diluted with water to produce a chemical release agent, combining the outstanding release properties of such materials with the economy of a conventional oil. It reacts with the alkali in the concrete to form a thin water repellent skin on the surface of the mould which enables easy stripping from the hardened concrete.

K2 CONFIBRE is a high performance micro polypropylene fibre developed as a crack controlling additive for concrete and mortar.It is used to inhibit the formation of small cracks which can occur through plastic shrinkage, premature drying and early thermal changes in order to provide utilization of the intrinsic properties of the hardened Cementitious material. It is a unique, specially treated fibre reinforcement which instantly disperses out through the mix ensures tensile and compressive strength which improves the durability of the structure.

Nitobond SBR(Latex) is modifi ed styrene butadiene emulsion specially designed for use as a bonding aid and gauging liquid for cementitious systems. It is resistant to hydrolysis and can therefore be used for external applications too.

Latex based Mortar and screed modifi er & bonding agent Uses For modifying and improving bonding of fl oor toppings, renderings and mortars; repair of worn, damaged and spalled concrete, repair of large cracks; polymer modifi ed fl oor screeds; waterproof plasters for masonary and slurries. Advantages  Simple to use - Single component, gauged as required. High - Provides excellent bond to concrete, adhesion plaster, masonry, stone work, etc. Improves -Gives weather resistant mortar with improved durability impermeability to chlorides and other harmful agents.  Reduces - Provides waterproof screeds, plasters and Permeability slurries. Increases - Improved tensile and fl exural properties strength allow thin applications.  Versatile - Compatible with all common hydraulic cements.  Cost eff ective - Nitobond SBR (Latex) is economical to use

Additives for shotcrete, a technique currently indispensable in the procedures of support and structural coating of tunnels and slopes.

To clarify some concepts:

• Gunitar is understood as the commissioning of a concrete or mortar sprayed with pressurized air through a hose, at high speed on a support.
• The shotcrete is a concrete whose maximum size of aggregates is greater than 8 mm, and that applied by machine, is projected at high speed on a support through hose and nozzle.
• The projected mortar is a mortar whose maximum aggregate size will not exceed 8 mm, and which, when applied by machine, is projected at high speed on a surface through a hose and nozzle.

Currently three different processes are used, which are:

• The wet mixing process involves the use of more services, but its use is widespread for large applications.
• The semi-wet mixing system, which consists in the dosing of water, approximately 5 m before the nozzle, is a process that fundamentally prevents the dry mixture from dispersing (especially the cement) when making the projection.
• The Dry Mixing System, whereby all the concrete components are pre-mixed, except water, which is added to the nozzle before the mixture is projected, the dry mixture being transported through hoses pneumatically until nozzle.

The most commonly used additives and additives in dry-cast concrete are accelerators (dust or liquid), silica smoke (dust or slurry), setting stabilizers, steel fibers and fly ash.

The most commonly used additives and additions in wet shot concrete are accelerators (liquid or powder), superplasticizers, silica fume (powder or slurry), setting stabilizers, rebound reducers, steel fibers or polypropylene and fly ash.
