NYS2-4C-Nano silica for concrete

This product is a nano-silica paste with small particle size, many micropores, large specific surface area, and high surface hydroxyl content. It has not been dried and its activity remains intact. When added in a certain amount to cement concrete, it is easy to form chemical bonds with the hydration products in the concrete, and can form a three-dimensional network structure in the cement slurry, which can improve the mechanical properties such as the early strength of the concrete, as well as improve the resistance to penetration, corrosion, and Weather resistance and other properties.

product description

Features

　　1. This product is an undried nano-silica cake material with high surface activity, no odor and no pollution;

　　2. Small particle size, large surface area, and strong hydrophilicity;

　　3. Good dispersion;

　　4. Improve the anti-penetration, anti-corrosion, weather resistance and other properties of concrete;

　　5. Improve the bending resistance, compression resistance and other mechanical properties of concrete at all ages, especially the early strength and high stress levels, and improve the stress cycle times of cement concrete;

　　6. The dry shrinkage of cement concrete is better than that of ordinary cement concrete, and the slump and expansion of concrete are improved at the same time.

Application and usage instructions

　　Products are used in the field of concrete. When using, the product is first dispersed into water through high-speed dispersion or ultrasonic dispersion to form a suspension of a certain concentration, and then the dispersion is added to other mixtures. Customers can choose the amount of addition according to the actual situation.

　　1. To improve the mechanical properties of concrete, the appropriate amount of nano-silica should be controlled between 0.5% and 1.0%.

　　2. To improve the frost resistance and durability of concrete, it is recommended to add 1%-3% of nano-silica.

　　3. To improve the chloride ion penetration resistance of concrete, it is recommended that the addition amount of nano-silica is 3%-5%.

　　At the same time, nano-silica doping will increase the consistency of concrete, reduce its fluidity, slump, and affect working performance. The amount of water-reducing agent needs to be adjusted appropriately.
