LN 352 PLASTICIZER
Water Reducer And Water Retarder Plasticizer
LN352 PLASTICIZER is a retarding & water reducing admixture. Retard the setting time of concrete and to reduce water requirement for a specified workability.
LN352 PLASTICIZER is based on processed sodium Nephthaline formaldyhyde. It acts as both a set-retarder and as a plasticizer. When added to concrete mixes the admixture is absorbed onto the cement particles. It then acts as a dispersing agent which breaks down agglomerates of cement particles and enables the water in the mix to perform more efficiently. It delays the initial hydration of the cement which results in retardation of the setting time. As a retarder, it can be used to extend setting time in high ambient temperatures, where mass concreting is involved such as foundations, water retaining structures, silos, piles and slip from structures where long delays or interruption can lead to problems or where cold joints have to be avoided. As a plasticizer, Cement reduction up to 10% is possible for a given workability and strength. Hardening: At higher temperature concrete hardens more rapidly and may impose problems with placing and finishing of concrete.
It can use with all types of Portland cement. As a retarder, it can be used to extend setting time in high ambient temperatures, it can be used to increase workability without addition of water or obtain increased strength by reducing water content for a given workability.
Avoids cold joints
Increases strength due to reduction in water
Can be used with pump concrete

The optimum dosage is best determined by site trials with the concrete mix which enables the effects of workability, strength gain or cement reduction to be measured. Site trials with LN 352 should always be compared with mix containing no admixture. As a guide, the rate of addition is generally in the range of 0.5 – 2.0 litres /100 kg cement.
