Curing after concreting is important for the strength and durability of concrete.

• Curing helps to prevent the loss of moisture from the concrete, which is necessary for the chemical reaction that gives concrete its strength.

• It also helps to prevent cracking and shrinkage of the concrete as it dries.

• Curing can be done by keeping the concrete wet, covering it with a membrane to prevent moisture loss, or applying a curing ...read more

The load capacity of a scaffolding prop depends on its size and material.

• The load capacity of a scaffolding prop can range from 20 kN to 60 kN.

• The size and material of the prop determine its load capacity.

• Steel props are stronger than aluminum props.

• The load capacity of a prop should be checked before use to ensure safety.

The % of retaining good aggregates depends on various factors such as quality of raw materials, production process, and storage conditions.

• The quality of raw materials used in the production process affects the retention of good aggregates.

• The production process should be carefully monitored to ensure that the aggregates are not damaged during handling and mixing.

• Proper storage conditions such as temperature and humidi...read more
