Product description

Retarding, High Range Water Reducing Admixture

Plastit SPNR is a chloride free water reducing admixture based on selected sulphonated napthalene polymers. It is supplied as a brown solution which instantly disperses in water. Plastit SPNR disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. The initial hydration of the cement is also delayed, resulting in a delay in the setting time of the concrete with no adverse effect on subsequent stiffening and strength gain. Plastit SPNR is suitable for concrete with water-cement ratio is higher than 40%.
The optimum dosage of Plastit SPNR to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is 0.7 to 1.5 Kg/100 kg of cementitious material, including PFA, GGBFS and microsilica.
Plastit SPNR complies with BS 5075 Part 1, ASTM C494 as Type B, D and G.
