Super plasticizer NR-30 is a liquid additive based on poly-carboxylates which is very strong & considerable in concrete performance and a strong reduction of concrete mixing water. The real goal of consuming this product in compliance with rules and regulations mentioned in Iranian Concrete Circulars is to make concretes with high slump and best quality and pressure resistance more than standard.
Slump increase Increasing the concrete efficiency without water increase Concrete making with maintenance efficiency between 30-60 minutes according to the consumption rate and primary efficiency Increase of concrete pressure / bending resistance in different ages Lack of change in primary/final trapping of concrete Increase the cohesion and decrease the permeability of concrete Increase the durability of concrete Easy pumping & increase the pumping Reduction of depreciation of concrete pumping equipment Prevention from creeping & shrinkage of concrete Compatibility with various types of Portland & SRC cements Reduction of vibration rate due to the suitable efficiency
The calculated plasticizer should be diluted with 2 times of water volume and according to the concrete grade. Diluted ingredient should be added little by little to mixing concrete.
It is possible to add the above-mentioned product to the ready concrete and perform concreting after complete mixing. It is suggested to mix the same for at least 1 minute.
The carboxylates plasticizer could be added to batching or truck-mixer while producing concrete.
Be careful not to pour the carboxylates concrete plasticizer directly on concrete dry materials.
Exact consumption rate depends upon various factors such as temperature, type of concrete, mixing plan and primary slump rate. It could be about %0.4 up to %1.1 of cement weight.
