Usage & General Recommendations:
All concrete ingredients (cement, aggregates, mixing water & admixtures) should comply with the relevant standards. Local (or international) concrete codes should be referred to, and appropriate design parameters (eg. cement type, minimum cement content, maximum W/C ratio and concrete strength class) must be selected depending on the requirements of the application, and according to international standards. Avoid casting concrete in temperatures less than 5 _C and above 35 _C.
In general, the more water is used for a given quantity of cement, the more porous and thus the weaker the concrete will be. It is therefore important to use the minimum amount of water required to make the mix workable, in order to obtain a strong and durable hardened concrete.
Make sure to use clean water for mixing, watering and spraying.
It is recommended to mix the constituents in a fully automated batching plant.
For non-automated concrete production (hand mixing or mixing by portable mixers), accurate measurement of all ingredients with a suitable container (wheelbarrow or bucket) is essential. Materials should be mixed until a uniform color is obtained. Adding too much water should be avoided.
Concrete or plaster should be watered for a period no less than 3 days to prevent cracking and to ensure proper strength development. In hot weather, concrete or plaster should be watered for 7 days. Following the placement, horizontal concrete surfaces should be sprayed gently with water, be cured by pulverized agents or protected with plastic (or wet hessian) sheets, in order to prevent drying shrinkage and water evaporation.
Available in bulk, 50kg bags or 1.5 ton jumbo bags throughout
from adverse atmospheric conditions.
Health and Safety:
Cement and concrete in general, may cause skin irritation. During any application, wearing gloves and eye glasses is highly recommended. In case cement touches the eyes or bare skin, the area should be thoroughly rinsed with free flowing water and medical assistance be provided when necessary.
