Supply of antifreeze, mortar antifreeze, pumping antifreeze, salt antifreeze, antifreeze concrete Jilin concrete antifreeze antifreeze manufacturers + price + special antifreeze minus 45 ℃ use performance standards: JC475-2004 I. Introduction antifreeze is by the early strength and antifreeze component, composite and entraining water reducing component consisting of a composite type antifreeze, the antifreeze with a low dosage, high early strength, not chlorine salt to prevent corrosion, easy to use and reliable, antifreeze effect is remarkable characteristics, can be widely used in industrial and civil construction of a variety of concrete projects. Concrete mixing this product and can be cast in concrete construction in winter than the daily minimum temperature -10 ℃, do not take the heat conservation measures, you can make fresh concrete from freezing, at negative temperature setting and hardening, and at a specified time within the expected strength. Second, the main technical characteristics and application of this product compared with other concrete antifreeze has the following features: 1. This product is a powder and liquid two forms. 2. This product does not contain chlorine salt, no corrosion of steel harm, for a variety of reinforced concrete works. 3. This product does not contain strong alkaline substances such as K2CO3, the human body without alkaline corrosion, no quick-setting phenomenon, does not affect the construction work time. 4. This product is greater than 12% reduction of water and have a wide variety of portland cement adaptability. 5. This product early strength, good frost effect, the performance reached JC475-2004 first grade standards. 6. It can be used under conditions of daily minimum temperature of -20 ℃ construction of concrete projects or daily minimum temperature of -20 ℃ conditions under mortar construction projects. Third, quality indicators 1. Homogeneity index Item Appearance powder gray powder dark brown liquid water content,% ≥95% ≥40% PH value 7-9 7-9 None None chloride ion content of the fineness of 0.315 standard sieve, 11.5% - cement paste fluidity, mm ≥180 ≥180 2. adding antifreeze concrete performance test project JC475-2004 (-15 ℃) First grade index test results (content 5.0%) water reduction rate,% ≥10 15 bleeding rate ratio,% ≤80 55 gas content,% ≥2.5 3.0 condense the time difference, min initial setting of -150 to + 150-35 final setting of -50 compressive strength ratio,%, standard provisions raise R28 ≥95 122 negative temperature -15 ℃ R-7 ≥10 15 R-7 + 28 ≥85 102 R-7 + 56 ≥100 111 steel corrosion effects should describe the role of non-rusting steel without use of methods used under 1. positive temperature early strength agent dosage is: 2-3% 2. Content negative temperature: -5 ℃ mixed 3 ~ 4%; - 10 ℃ Volume 4 ~ 5%; - 15 ℃ dosage of 5 to 7 percent. 3. The product can be directly input and aggregate together, mixing time required to extend the 2 to 3 minutes. 4. Every shipment must be tested with test cells, can be used. Fifth, the construction process requirements 1. Stir before, rinse with hot water or steam mixer. To join the sand, gravel and water stir 1min, then add cement and antifreeze stirring 3min. Stir the water temperature to determine the basis of ensuring the concrete into the mold temperature ≥10 ℃. 2. In the case of meet the normal construction to minimize water consumption; because the concrete free water increased, decreased frost resistance. Antifreeze mixed with a dry concrete mix characteristics rather than hard, pay attention to controlling the fresh concrete slump is not too large. 3. sand, stone canvas or plastic sheeting to cover the use, to prevent gravel from freezing. Cement may not be directly heated, one day before using and storing transported into greenhouses, keep it positive temperature. 4. Before pouring the concrete, should be cleared of snow and ice and dirt on the template and steel. But not by direct steam to melt snow and ice, in order to avoid freezing again. Promptly remove concrete residue container adhesion and timely removal of snow and ice frozen block, after container Gaiyan insulation. The exposed surface of fresh concrete, timely cover with plastic film insulation materials under conditions of negative temperature curing, concrete not watering. Press with the pouring, with the vibration, the principles covered with continuous operation. 5. Portland cement or cement should be used in ordinary Portland cement. Sand, stone to clean the sieve, shall not contain ice, snow and other objects and easy to freeze the cracking of the material. 6. This product is mixed with cement concrete not less than 300kg / m3, water-cement ratio of not more than 0.6. 7. The "concrete admixture technical specifications GB50119-2003" requirements, adding a variety of antifreeze concrete's temperature not lower than 10 ℃, into the mold at a temperature not lower than 5 ℃, the insulation should be covered with concrete pouring prevent dry and frozen dehydration. 8. matters not covered in this manual, please observe the relevant provisions of the "reinforced concrete works and acceptance (JBJ204)" and "concrete admixture technical specifications (GB50119-2003)" in. VI, packaging, transportation and storage 1. The powder using woven bag with plastic bag, net weight 50kg, 200 kg of liquid for big drum, can also be packaged according to user requirements. Powder should be stored in dry and ventilated warehouse dedicated, valid for two years. 2. transportation, special powder to prevent sharp objects scratching, avoid broken package moisture. 3. The agent if wet agglomeration, treatment methods are two kinds: (1) crushed by 0.315mm sieve, then use; (2) the use of melt into liquid. If this product over the period, can still be used after passing inspection
