One of the problems of the production of artificial stone of cement plast, as well as concrete, especially in winter and cold weather, is the increase in the duration of processing, or the drying of concrete or artificial stone. therefore, to accelerate the hydration and polymerization reactions, it is possible to use early hardening Nano
Also, using this article, you can achieve results such as:
An increase of about 5 to 15% of the surface erosion of the product (Assuming that the amount of cement used is fixed, according to the fixed formula and also with the dose of this substance) this material (Nano flood accelerator)
It increases the flexural strength of the product by 10 to 20 percent, as compared to the previous formula (Due to stronger crystallization and more in cement)
It reduces the duration of the concrete's final strength (The final strength of the product is after 28 days) depending on the dose, this period is reduced to 10-14 days
Increasing the compressive strength of products by 10-20% compared to the previous formula
Due to the presence of Nano materials in intermolecular bonds, it reduces surface and absolute water absorption of the product according to the amount of consumption (20-30% reduction in product water absorption than constant formula)
Increasing the frost resistance due to the filling of continuous and discontinuous cavities in the product tissue
More glossy product due to reduced processing time and accelerated product curing process
Physical properties of early hardening Nano product of artificial stone cement plast:
Concentrated suspensions of calcium silicate hydrate nano-particles are white
This material is without chlorine ion, as well as without impact on the priming of concrete and artificial stone cement plast
PH = 11-12
The mechanism of early, hardening nanosil behavior (accelerator) on artificial stone cement plast:
When the cement is combined with water (the hydration reaction), the nano-particles of calcium silicate hydrate are large in size between the particles of the cement and act like a bud in the cement
Calcium silicate hydrate (early hardening nanosil) resulting from hydration of cement grows on these buds, in other words, all the cement particles start to simulate and reproduce in an intelligent manner at once. and thus leads to a tightening and secondary fixation in concrete and artificial stone cement plast.
Amount of consumption early hardening nanosil artificial stone cement plast
The consumption rate is based on the different weather conditions and the storage temperature of the product to the variable processing and between 2 to 5 percent for the artificial stone cement plast and between 1 and 4 percent for the concrete.
Conditions for the storage conditions of early hardening nanosil of concrete and artificial stone:
At temperatures above 5 ° C, and away from direct sunlight, it will be between 9 and 10 months
How to use early hardening nanosil of artificial stone cement plast:
Due to weather conditions, and the storage temperature of the product until the curing of the concrete or artificial stone cement plast, the amount of 1 to 5% is added when adding water to the mixture.
this material It has no effect on initial tightening
Advantages of early hardening nanosil of artificial stone cement plast:
Reduce the duration of concrete curing and drying concrete
Reduce curing time in artificial stone cement plast in the summer and especially in the winter (Minimum storage time is between 8 and 10 hours in winter)
Decrease the opening time of artificial stone cement plast from the mold in the winter from at least 24 hours to a maximum of 10 hours
Due to increased speed of hydration and polymerization, the product is treated earlier and prevents adhesion of materials to molds.
Low grade cement converts to high grade cement in terms of strength and hardness
Ability to reduce 5 to 10 percent of consumed cement, for every one percent of the early hardening nanosil
Increases by 10-20% to the compressive strength of the final product
Increasing the density, increasing the abrasion resistance and reducing the water absorption in the product
Compatibility with various types of concrete additives and lubricants (If using this additive, don't use early hardening nanosil)
