Type SAC-1 Rapid-setting Accelerator
for CSA Cement and High Alumina Cement
Summary
● Type SAC-1 Rapid-setting Accelerator, is a kind of early strength admixture for Calcium Sulfoaluminate Cement (CSA Cement) and High Alumina Cement (HAC, also named Calcium Aluminate Cement).
● Type SAC-1 can effectively cause cement mortar products and concrete of CSA Cement and HAC rapid setting, fast hardening and fast demould. Sometimes, type SAC-1 Rapid-setting Accelerator is also named Fast-hardening Additive or Early-strength Additive for GRC cement products.
● When using type SAC-1 Rapid-setting Accelerator, it can shorten greatly setting hardening time of CSA Cement and HAC products so get the result of fast demoulding, and does not reduce strength of cement grade, at the same time it can make the cement or concrete products early strength and fast hardening, and the strength value will increase about 8% to 10%.
● Type: SAC-1
● Served Cement Type: Calcium Sulfoaluminate Cement(CSA Cement, CSA Binder), Calcium Aluminate Cement(High Alumina Cement, HAC)
Characteristics
● Appearance: dust color powder
● Rapid-setting: effectively reducing initial setting and final setting; more added quantity of SAC-I and more high temperature of mixed water, will cause shorter setting and more fast hardening of cement.
● High-strength and Early-strength: effectively increasing early strength and final strength of CSA cement and HAC products; more mixed quantity of SAC-I will bring more high strength.
● Fast-hardening Demoulding: to adjust mixed quantity of type SAC-I to suitable ratio and improving mixing water temperature, it can get the effect of faster demoulding for example about 30 minutes to 1 hour, or more short time.
● Recommended Water-reducing Ratio: about 5 to15%
● It does not belong to flammable solids, corrosives, toxic substance, dangerous goods.
● Non-burned
● It is environmental friendly to surroundings, free of poisonous heavy metal contents such as chromium(Cr), plumbum(Pb), hydrargyrum(Hg), and chlorine salt composition(Cl) etc.
Technical Character
● Fineness(materials retained on 0.08mm screen): 5%Max
● Water Content: 0.5%Max
Application
Type SAC-1 Rapid-setting Accelerator is suitable for making the products and construction projects made of CSA Cement and HAC:
● GRC cement products, Artwares, European style products, Landscape arts;
● Wall Plates, Cement Bricks, Flowerpot, decorative articles;
● Fast patching of concrete surface of diverse roads and bridges;
● Fast concrete construction in winter;
● Foaming cement boards and foaming concrete products;
● Sulfate resistance construction projects;
● Construction of mines, sea wall, dam, river embankment;
● Other cement or concrete products made of CSA Cement and HAC.
Uasge
● Recommended Added Quantity: 0.5 to 5.0% of cement weight.
The factual final added quantity must be confirmed as per performance request of mortar or concrete, and different ratio and change of mixing materials, and different production and construction condition; the test result in labs will be as the final added data.
When batches of cement and type SAC-I are changed, for the new and exact added quantity, the trial in Labs must be done again.
● W/C Ratio recommended: about 0.30, or to adjust the suitable ratio as per the factual request
● Temperature of working room and mixing water: normal temperature; if the temperature of working condition is lower or for getting the faster hardening and demoulding time, it is the best to improve the temperature of mixing water 50℃-60℃, but the highest water temperature not more than 60℃.
● Mixing Process: first to mix type SAC-I in dry together with cement and/or other dry aggrehates to even, then to add weighted mixing water and continue to mix to even, recommended mixing time in dry and wet not less than 3 minutes.
● Notice to reduce the quantity of mixed water. Recommend water-reducing ratio about 5 to15%.
● If it is necessary to increase W/C ratio, please add more water then to get the enough operation time.
● After demoulding, the cement products must be cured in wet.
● Blocked or wetted cement can not be allowed to use again.
Transport, Storage and Package
● Transport: Classification for conveyance - not required. During the transportation of a large of amount of batteries by ship, trailer or railway, do not leave them in the places of high temperatures and do not allow to exposed to moisture. During the transportation do not allow the packages to be fallen down or damaged.
● Storage: to be stored with intact sack in dry. If the sack open, it should be use soon to avoid to be damaged.
● Package: plastic woven bag with sole PP bag, 25kg/bag, and /or big bag.
