Inorganic liquid accelerant, for sprayed conglomerates (shotcrete)

Code: ADX.0063

Components: 1

Appearance: Liquid

Solution of mineral reactives (sodium silicate) to be used for the acceleration of setting of sprayed masonry and projected concretes, in the reinforcement of rocks outdoors and/or in a gallery, in laying self-sustaining and waterproofing claddings of tunnels, channels, vaults, basins, underground structures, etc., for use with specific equipment for hydrated mixtures (mixtures in which the silicate is sprayed on the shotcrete output nozzle).

FLUID SPRITZ is a wide diffusion accelerant characterised by ease of use, dosage variability according to the specific construction needs: reduction in the number of coating layers to be applied, reduction of patch layer laying time, reduction of rebound swarfs, option to operate even in cold weather.


Use from 10 to 15% of FLUID SPRITZ on the weight of cement present in the mixture to be projected and based on the application conditions and type of concrete (range of use: between 35 and 70 kg per cubic metre).

Use fields

Production of mortars and grouts sprayed with specific equipment (pumps for shotcrete machines) for hydrated mixtures in the reinforcement of rocks outdoors and/or in a gallery, in laying claddings, also with a load-bearing function, in galleries, on piles, sheet piles, diaphragms, channels, vaults, pondage, etc. In waterproofing underground structures. It can be used in structural sheets, for the safety of buildings affected by earthquakes.

Use method

FLUID SPRITZ must be previously introduced into a tank of suitable capacity to be added directly to the spray nozzle. It is always advisable to carry out preliminary tests to determine the most appropriate percentage product addition.

Application methods

- To be added to other components

- Shotcrete machine

Tool cleaning

- Water

Permitted supports

- Concrete

- Bricks

- Tuff

- Mixed walls (bricks and stones)

- Stone walls

- Rock walls

Warnings, precautions and Ecology

The acceleration depends not only on the dosing of FLUID SPRITZ but also on the strength of the cement and the granulometric composition of the mixtures, the mineralogical properties of media and of the aggregates, the environmental temperature and humidity conditions, and so on.
