Product overview This product is combined naphthalene high efficiency water reducing elements with several types of accelerating and anti-freezing components. It is mainly applied in pumping concrete manufactured in winter constructions. This product meets GB8076 and JC473 first-class standard. Benefits Efficiently decrease the freezing point of free water in concrete Accelerate the hydration of concrete in cold weather; enhance the early stage strength of concrete and anti-freezing ability Improve the flow ability workability and pumpability of concrete Small rate of slump loss, no segregation, no bleeding Improve the strength of concrete in every state and increase the duration after hardening. Improve impermeability, anti-freezing ability and durability Low level of alkalis, no corrosion to the steel structures Areas of Application All types of pumping concrete and commercial concrete in winter constructions. Commercial concrete and large-scale concrete structures, such as highway, railway, bridge, harbor, industrial and civil facility projects Applicable condition: NOF®-D1: rated temperature ¡Ý -15¡æ; outdoor temperature ¡Ý -20¡æ NOF®-D2: rated temperature ¡Ý -10¡æ; outdoor temperature ¡Ý -15. Method and cautions Dosage (total cementitious materials): Powder 2.0~3.0%, Liquid 2.0~3.0% Powder admixture can be added with binding materials, liquid with mixing water. Increase mixing time properly. Hot water helps to improve its performance. In winter constructions, no ice, snow or freezing elements in aggregate materials. Raw materials should be pre-heated if possible. After pouring, cover plastic film and enhance thermal insulation curing. The optimum mix design needs to be determined by the requirements of the project, specialties of materials and mixture tests before usage. The feasibility of combination with other admixtures needs to be conformed by mixture tests. This powder product is packed into plastic knitting bags, 50 kg/bag; the liquid product is packed into plastic barrel, 200~250kg/BBL or transported by tankers. During storage, it needs to be prevented from moist, broken packed and high temperature. The effective duration is one year. Expired product needs to be determined by tests. This product is not inflammable or explosive and need to be well kept.
