Uses
Today, with the increase in the volume of concreting and the rise of world standards, the basic need for high quality concrete is felt. Super Plast superplasticizer group is used to improve this and to obtain concrete with suitable performance in optimum and rational water/cement ratio.
Description
Modified naphthalene-formaldehyde based Super Plast N390 concrete super plasticezer improves many properties of concrete without this substance, causing easy movement of the concrete in the mold and between the rebars, smooth fluidity and efficiency, and minimizing vibration. This superplasticizer has no effect on the setting time of concrete. However, it can be delayed by adding a Retarder to it.
Advantages
- Increasing slump and reducing or eliminating vibration
- Water reduction of up to 25% and consequently increasing the compressive strength and, to some extent, flexural strength of concrete.
- Very good cooperation with Microsilica, FLY Ash and other pozzolans.
- Compatibility with all kinds of Portland and anti-sulphate cements.
- Suitability for use in ready-mixed concrete at the concreting site.
Recommended Dosage
The exact amount of use is determined by the basic needs of the design and materials involved in construction, but an amount of 0.6% to 2% by weight of cement is recommended.
Application
In laboratory conditions; Dissolve the specified amount of Super Plast N390 in all of the specified water, pour it into the concrete and allow the mixing process to continue for two to three minutes.
In construction conditions; Add the specified amount of Super Plast N390 at the same time as the water entering the concrete, and if the concrete enters ready for construction, add Super Plast N390 from the end valve of the mixer and let the mixer rotate 90 - 100 times at high rotational state. Since Super Plast N390 performs all its chemical activity in the presence of water, avoid pouring this substance on dry materials.
