LEARN TO OPTIMIZE TIMES OF LOADING AND DOWNLOADING THE CEMENT IN A WORK

The cement that remains dry retains all its physical and chemical characteristics, so it is very important that at the time of transport is kept in good condition. However, the current trend is to distribute it in bulk, transporting it in tankers or bulk carriers and storing it in silos.

Below are some advantages of the cement economy:

• Obtain savings on the purchase of cement.
• Have the operating economy in discharges, storage and handling.
• In the economy have losses, originating in damaged or wet bags.
• Increase in the productivity of the work, because cement is available immediately.
• To avoid the risk of theft.

It is a tank or tank under pressure in steel or aluminum, towed by a tractor truck, which is loaded in storage silos by gravity, its capacity goes from 18 to 38 tons of cement and is generally provided with a compressor that is used To download the material.

The driver regulates the controls to give the proper mixture of air and cement that takes the material to the work silo.

Storage silos should have a filter system to mitigate emissions of cement dust into the atmosphere and keep vent pipes and ventilation devices clear to prevent damage from pressurizing of cement during discharge.

To be able to empty the cement correctly:

• Place the concrete as close to its final position as possible.
• Start by placing the concrete from the corners of the frame or, in the case of a sloped site, from the lowest level.
• It must be emptied from heights less than 1.20 m. When it can not be done, use channels or tubes to prevent the mixture from colliding with the reinforcements and the form. In the case of using gutters, check that the slope of the gutter is between 30% and 50%.


The accesses of cement should have little slope and a firm base sufficient to support the indicated weight (32 -50 ton).
In this way, it is prevented that the transfer to the site of emptying undergo changes that affect its quality.
Below we have the following precautions are to take into account:
• Avoid excessive shock and vibration.
• Carrying distances of the mixture within the work must be less than 50 meters.
• Upon arrival at the placement site, a small manual mixing can be made into the vessel to reduce possible segregation.
