TherGlass Concrete ADMIX HD-100

Specifications and Application Form

Concrete is a porous material by nature, most often with micro-cracks, voids, pores and capillaries that mainly form in the early stages of curing.

The better connected these gaps are, the more permeable the concrete is and the more prone it is to damage caused by the ingress of water, liquids, and corrosive agents.

^{However, TherGlass Concrete ®}   ADMIX HD-100  technology  virtually eliminates concrete porosity and many of its inherent weaknesses, thereby increasing its durability.

TherGlass Concrete ^®   ADMIX HD-100  is added directly to the concrete mix during its manufacturing phase.

The dosage of TherGlass ^®  Concrete   The dosage is 1 kg of TherGlass Concrete ^®   ADMIX HD-100,     for each cubic meter of concrete and the water cement ratio (w/c) must be equal to or less than 0.5.

The addition of TherGlass Concrete ^®   ADMIX HD-100  may slightly modify the plastic properties of the concrete, which is why we recommend carrying out prior mixing tests to adjust the consistency of the concrete by incorporating fluidifying additives and never adding more water to the mix than designed.

TherGlass Concrete® ^ADMIX   HD-100   is compatible with most standard naphthalene sulfonate-based fluidizers. If using lignosulfonate-based, melamine-formaldehyde-based, or polycarboxylate-based fluidizers or superfluidizers, we recommend performing prior testing.

Mixing Process

Concrete Plant – Dry Mix

• Add TherGlass Concrete ^®  ADMIX HD-100,  powder, to the truck's mixing tank.
• Once the tank has been started, the remaining aggregates can be added following normal mixing practices.
• The materials must be mixed dry for at least 5 minutes, to ensure that the  ADMIX HD-100  additive has been evenly distributed throughout the concrete mass.

CONCRETE CENTRAL – GROUT MIX

• Mix  ADMIX HD-100  with water to form a very fluid, fine-textured slurry.
• Subsequently, pour all the concrete components (aggregates, cement and water) into the truck's mixing tank following the usual mixing process.
• Take into consideration the amount of water already used to make the grout.
• Pour the ADMIX HD-100  slurry  into the truck and mix for at least 5 minutes to ensure uniform distribution throughout the concrete mass.

PRECAST PLANT

• Add  ADMIX HD-100,  along with the aggregates and sand, mix well for 5 minutes.
• Add the cement and water and mix again following the usual mixing process.

Important:

• It is important to obtain a homogeneous mixture of  ADMIX HD-100 with the concrete. Therefore,  powdered ADMIX HD-100  should not be added directly to wet concrete to prevent the formation of lumps that would prevent the mixture from being evenly distributed.
• The mixing of TherGlass ^®  Concrete  ADMIX HD-100  with the rest of the concrete components will always be done with prior agitation at medium to high speed and never for less than 10 minutes before pouring.
• Even if the concrete contains the ADMIX HD-100 additive   ,  the need to make the corresponding designs for crack control, detailing of construction or expansion joints, as well as taking measures to repair defects in the concrete (e.g., holes, cracks exceeding permissible limits, etc.) is not excluded.
• For more information regarding the most appropriate use of TherGlass ^®  Concrete  ADMIX HD-100   for a specific project, contact your local TherGlass ^{®   technical representative.}

Joint treatment

Joints between the various concrete elements that make up the structure: slab-to-slab, wall-to-wall, slab-to-wall, pipe passages, through holes (splits), etc., should be treated according to our recommendations in our Technical Bulletin Application (TJS) 1.027  . TherGlass® ^Joint  System.

Cleaning

Fresh tools and implements can be cleaned with water. If the material has hardened, it can only be cleaned mechanically.

Dosages and Consumption

The dosage of  ADMIX HD-100  is 1 kg per m³ of concrete.
