Calcium
Used in the construction . Quick coagulant for cement , lubricants, early strength agent . For building a variety of concrete, mortar ( tile adhesives, cement-based plaster , repair mortar , waterproof mortar ) floor and concrete industries.
Accelerate cement hardening rate , shorten the setting time, especially in the winter construction, to avoid condensation at low temperatures too slow . Fast release , to improve the strength of cement into use as early as possible . Calcium Uses : Various dry mortar , a variety of concrete, wear-resistant materials , flooring industry , feed industry , tanning . Calcium and attention to issues involved in dosage per ton of dry mortar , concrete amount of about 0.5 to 1.0 %, the maximum dosage of 2.5%. Calcium dosage is decreased as the temperature gradually increased , even if the application amount of 0.3-0.5 % in the summer , and will play a significant early strength .
Storage: store in a cool dry place , use within six months.
