Recommended mix proportions by volume using CEM II B-LL 32.5N

Aggregate
Aggregate have a significant influence on strength, quality and durability of concrete, mortar and plaster. We recommend using aggregates from reputable suppliers.

Sand
The sand used should not contain organic material (dung, roots, leaves), nor too much fines / clay, which may lead to loss of strength or excessive water demand.

Water
Quality of water is important! Use clean drinkable water to achieve a workable concrete.
The less water in the mixture, the stronger the concrete, mortar or plaster.

Curing
After the concrete, mortar and plaster have hardened, keep them moist by spraying with water and covering with light coloured plastic sheeting to prevent evaporation for up to 7 days.

Ohorongo Cement is distributed in 50 kg bags, 2 ton bags and bulk tankers. Bulk storage silos should be dry and vapor tight.

Cement bags should be protected from moisture and kept dry, preferably off ground by means of pallets or timber, preventing moisture contact. Bags should be stored away from direct sunlight, or should be covered by a roof or sheeting. Stacking should be kept to a maximum of two pallets high to avoid compaction of cement bags at the bottom.
