Concrete surface preparation and coating selection – SSPC

The concrete surface preparation method on a given surface will vary based on how contaminated, damaged or otherwise compromised it is. For instance, a surface may be in good enough shape to need relatively low-impact measures that will not alter the surface profile, such as vacuum cleaning, low-pressure water cleaning and washing or scrubbing ...

Air & Water Quality Guideline

If a mobile batch plant is used for the preparation of concrete, the plant must not be positioned closer than 50 metres to an environmentally sensitive location. In addition, where possible a buffer zone of 100 metres from any township, municipality or residential dwelling should be provided when batching concrete. Air quality management

Batching, Mixing, Placing and Compaction of Concrete

Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...
