Serves Tianjin Concrete antifreeze early strength agent 15942681994

Concrete early strength antifreeze concrete early strength antifreeze (requiring temperature -15 ---- 20 ° C) Executive Standard: JC475-2004 the early strength antifreeze case of composite antifreeze. It has early strength, antifreeze and bleed air, water, water soluble, low ash characteristics, can significantly alter the workability, pumpability, slump loss. Particularly for pumping concrete and commercial concrete mixing plant winter construction alkali - aggregate reaction does not occur, and other concrete antifreeze, enhanced durability of concrete buildings, can reduce the cost of concrete construction in winter, economic benefits significant. Technical features: early strength, air-entraining, antifreeze effect, can be used for the daily minimum temperature of 0 ℃ ~ -20 ℃ concrete construction, no corrosion of steel. Scope: all kinds of industrial, civilian use of cast-in-place or precast concrete, highways, airports, tunnels, bridges and other reinforced and prestressed reinforced concrete. The early strength antifreeze technical indicators project standard specifies First grade technical indicators early strength the the antifreeze water reduction rate (%) ≥ 10 containing gas (%) ≥ 2.5 3.0 Bleeding rate ratio (%) ≤ 100 35 compressive strength ratio (%) of the specified temperature ℃ -5 -10 -15 -5 -10 -15 R-7d 20 12 10 25 16 R28d 95 95 90 110 110 110 R-7 +28 d 95 90 85 108 100 95 R-7 +56 d 100 115,110,105 condense the time difference (min) the initial setting of -120 to +120 +30 final setting of -120 to +120 +45 impermeability height ratio (%) ≤ 100 70 alkali content (kg/m3) ≤ 0.65 90d contraction ratio (%) ≤ 120 105 50 times freeze-thaw strength loss rate ratio (%) ≤ 100 55 Corrosion to steel bars should be no corrosion of steel without corrosion homogeneous properties: Appearance: light gray powder; moisture content: ≤ 3%; fine : 0.315 sieve all through; cement paste fluidity ≥ 150mm. antifreeze Note: Our antifreeze used for construction in winter, according to customer requirements to configure different prices are as follows: 1, liquid concrete antifreeze, mortar antifreeze 3 plain concrete antifreeze, salt-free antifreeze (powder, liquid)
