DRACO
DRACRIL XTIME is a particularly suitable admixture for the production of ready-mix concrete in hot climates where you want to achieve maximum control of Slump Loss. DRACRIL XTIME allows you to manufacture high performance concretes characterised by a very low water-cement ratio and excellent rheological qualities and cohesion even in the more fluid consistency classes.
Advantages:
It can be used to produce high-performance concrete in hot climates with low W/C ratios (0.4) and superfluid consistency (S5) so as to increase its life cycle;
It keeps its consistency features unchanged for an hour according to the W/C ratio and cement type used;
If you add FILLCRETE (Silica Fume) or fl y ash, a larger proportion of DRACRIL XTIME than the weight of the concrete, you can produce special kinds of concrete, such as HPC concrete and RPC concrete;
The resulting concrete develops high mechanical strength to short curing even if its heat cycle is short;
It can produce long-term concrete particularly resistant to aggressive agents;
It can cut down on the costs for concrete casting because it increases workability time;
It makes it easy to cast concrete into thin cross sections even if many reinforcement bars are in place;
It helps avoid segregation and bleeding, but it makes concrete stiffer and more homogeneous;
It takes less time to vibrate concrete or, in the case of self-compacting concrete, it can give the chance to skip the concrete vibration process if it is used in combination with VISCOCONTROL. In this way if offers great technical application advantages and it reduces the exposure to noise;
It improves the quality of concrete for quarry faces and the concrete-iron adhesion, but it also increases the abrasion resistance of every concrete mix;
It ensures a better surface fi nishing and it reduces the amount of trapped air bubbles;
It reduces creep rates and hygrometric shrinkage, but it increases the adhesion to reinforcement bars.
Uses:
High-resistance concrete later supplemented with silica fume, fly ash, slag additives, etc;
Ready-mixed concrete in hot climates and long-distance transport;
Concrete handwork with very low W/C-ratios and resistant to aggressive agents, such as chlorides, sulphates, carbon dioxide;
Casts of structures with thin cross sections;
Concrete reinforced with steel fibre FIBERMIX;
Shrinkage-compensating concrete along with the use of expansive agent EXPAN 25;
Self-compacting concrete in combination with rheological additive VISCOCONTROL.
