TriAl and Caltra produce innovative building products including high-strength dry mortars and cement binders. These products require careful mixing to achieve their full strength and durability benefits. The document outlines a five-step mixing protocol for these products: 1) dry mix ingredients, 2) introduce pigment, 3) wet mix, 4) continue mixing until lump-free, and 5) introduce fibers while continuing to mix. It is important not to add extra water beyond the specified amount and to ensure thorough mixing for the full recommended time. Following these steps results in a high-fluidity mixture that delivers high strength and durability.

2. TriAl bv based in Holland specializes in development , production and marketing of
innovative building products.
A series of high fluidity , high early strength and rapid drying dry-mortars and
cementious binders today find their way to the international markets.
This presentation features the best way of mixing and using these revolutionary
products as it is clear that because of its special chemistry they need careful
treatment.

3. In making concrete or mortar, water is needed to harden the cement binder.
To obtain a certain workability / flow an excess of water is used / needed.
This excess water lowers considerably the strength of the concrete / mortar,
increases the porosity and shrinkage and reduces the durability of the mortar or
concrete.
In order to achieve a concrete / mortar with high or ultra high strength paired to a
good flow, binder ratio and grading of fillers are optimized.
This enhances the workability and the mass is better compacted.
Use of “superplasticizers” is mandatory. It substantially reduces the water to cement
ratio and improves the rheology , flowability and workability of the mortar / concrete.
It also facilitates the use of fibers in order to increase ductility.
All this improves strength and durability of the mortar / concrete.
Provided ………adequate attention is given to proper mixing of the mortar / concrete

4. Because of the fineness and adsorption of some of the additives on the fine cement
particles combined with a relative low water amount, high yield stress
(intensiveness / time / speed of mixing) is needed to disperse all ingredients well.
To make this more clear following graph shows the best way to mix
For this reason when using these high strength cements / mortars in first instance the
mix seems to be too dry - one is tempted to add more water - NO this is not the way -
keep on (high shear) mixing the mortar / concrete and after a few minutes the right
viscosity is obtained, and can be extracted.
