Calcium aluminate cement

ELECTROLAND

CAC ELECTROLAND cement, manufactured by Cementos Molins Industrial, S.A., is a calcium aluminate cement with very high mechanical resistance at 6 and 24 hours and which is also resistant to aggressive environments (sulphates, marine, diluted acids), abrasion and high temperatures (refractory applications). It is also an excellent ally in the formulation of special mortars, joints and high-tech self-levelling pastes. ELECTROLAND is 100% ground clinker with no additives.

Shipping and storage	•Available in bulk, in big-bags of 1,050 kg, 1,200 kg and 1,500 kg and in 25 kg bags. • Sacks and big-bags should be stored in dry places and Ventilated. • Bulk storage must be done in watertight silos.
Recommended for mortars and concretes	• Fast hardening, even in cold weather. • Against attack by sulphates and certain acids (pH≥4). Bacteriological chemical resistance. • Resistant to abrasion and mechanical impact. • In products formulated by the chemical industry of the Construction with loosening and hardening properties (waterway covers, adhesives, repairing mortars, grouts, self-levelling. • Refractory, refractory-insulating and even shock-resistant thermal.
Not suitable for	• Structural or prestressed reinforced concrete. • Mass or reinforced concrete of large volumes. • Stabilization of soils or foundations treated with cements for Roads. • Mortars and concretes in contact with media that can release alkalis. • Forbidden for prestressed concrete, according to the Instruction of the Structural Concrete (EHE).
Precautions to be taken on site	• Given their high reactivity, mortars and concretes with Electroland must be cured within the first 24 hours. • Minimum cement dosage of 400 kg/cm³. • Maximum water/cement ratio of 0.40, counting the water that provided by aggregates. • Clean aggregates, with a few fines smaller than 0.2 mm, and not capable of releasing alkalis. • Make sure the concrete is well compacted.
