Concrete early-strength antifreeze
>rrrr
>Execution standard: "Concrete Antifreeze"
>Product Introduction
>Concrete early-strength antifreeze is a combination of winter construction temperatures Conditions, commercial concrete pumping, designed and developed to inhibit alkali aggregate reaction. It contains low alkali content and can accelerate the setting and hardening of concrete under negative temperature conditions. The strength increases significantly and does not affect the later strength development.
>Performance Features
>◎Suitable for winter construction when the temperature is not lower than ℃
>◎Can significantly improve the workability and pumpability of concrete
>◎Has anti-freeze and early strength and other functions
>◎Low alkali, can effectively avoid alkali aggregate reaction in concrete
>◎Good adaptability to various cements
>Application scope
>Anti-freeze Agents are divided into two types: chlorine salt-containing products and chlorine-free salt products.
>Chloride-containing antifreeze is mainly used in plain concrete. Chloride-free antifreeze is mainly used in reinforced concrete to prepare high-strength concrete constructed under negative temperature conditions, large fluidity concrete, and commercial concrete pumped concrete. Winter construction avoids corrosion of steel bars and improves the durability of concrete.
>Notes
>◎It must be mixed correctly according to the mix ratio, and the construction specifications must be strictly followed when pouring concrete.
>◎When the temperature is lower than ℃, hot water can be used to mix concrete. When the water temperature is higher than ℃, the hot water should be mixed with the aggregates first, and then the cement is added. When the temperature is lower than ℃, the aggregates can be moved into a greenhouse or taken Heating measures. The aggregate must be heated when freezing into blocks. The heating temperature should not be higher than ℃, and burning should be avoided. The moisture brought in by directly heating the aggregate with steam should be deducted from the mixing water.
>◎The molding temperature of concrete in severe cold areas shall not be lower than ℃, and in cold areas it shall not be lower than ℃.
>◎When curing under negative temperature conditions, no watering is allowed. After concrete is poured, it should be covered with plastic film and insulation materials immediately. Insulation measures should be strengthened in severely cold areas.
>◎Initial curing temperature shall not be lower than the specified temperature.
>◎When the temperature of the concrete drops to the specified temperature, the strength of the concrete must reach the critical frost resistance strength. When the minimum temperature is not lower than ℃, the compressive strength of the concrete must not be less than.
>◎When the difference between the surface temperature of the concrete after the formwork is removed and the ambient temperature is greater than ℃, it should be covered and cured with insulation materials.
