Product overview This product is combined several types of anti-freezing organic and inorganic anti-freezing components with accelerating components. It is mainly applied in fresh concrete and precast concrete units in winter constructions. This product meets JC473 standard. Benefits Efficiently decrease the freezing point of free water Accelerate the hydration of concrete in cold temperature; enhance the early stage strength of concrete and anti-freezing ability. Characteristics of accelerating, enhancement, water reducing and air-entraining Can function as early strength admixture Improve the physical mechanic ability and duration index of concrete. Low level of alkalis, no corrosion to the steel structures. Areas of Application All types of pumping concrete and commercial concrete in winter. Commercial concrete and large-scale concrete structures, such as highway, railway, bridge, harbor, industrial and civil facility projects Can be combined with water reducers to manufacture plasticizing and pumping concrete. Applicable condition: NOF®-D3: rated temperature ¡Ý -15¡æ; outdoor temperature ¡Ý -20¡æ NOF®-D4: rated temperature ¡Ý -10¡æ; outdoor temperature ¡Ý -15¡æ 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, 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.
