Raw Material Handling and Storage - Precast

Cement The majority of precast concrete plants today employ bulk cement in their operations. Bulk cement is stored in circular or square silos made of concrete or steel. Given that cement is sensitive to moisture and must remain dry until used, the silos must be watertight. If kept dry, cement will retain its quality for a very long time.

To test to see if moisture is coming up through concrete, you can tape a sheet of plastic over the concrete and leave it there for 24 hours. If there is condensation on the plastic when you peel it up, you need a moisture barrier. Once you have considered your climate and materials, you can decide if you need a vapor barrier for your floors.

What Happens When You Put a Plastic Vapor Barrier in Your ...

When a vapor barrier is on the side of a wall where the dry air is (i.e., outside in winter or inside in summer), moisture problems can occur. A vapor barrier reduces the movement of water vapor by diffusion. Holes in the vapor barrier that allow humid air through may allow a lot more water vapor into an assembly than the vapor barrier is stopping.

8 Truths about Concrete Moisture - Concrete Moisture

The ratio of water to cement in your batch of concrete remains one of the most influential factors as to how long a concrete slab needs to cure and dry. External sources of concrete moisture can also be substantial and include such things as rainwater, poor plumbing, poor drainage below or at the sides of the slab, and even the humidity in the air.

What You Need to Know About Rotary Feeders In Cement ...

In most cases, coal mill feeders are smaller than raw mill or finish mill feeders with capacities of 10-100 tons per hour. The #1 issue for coal mill operators is stickiness or coal build-up on all the material handling equipment, including the mill feeder. Raw coal, which is usually 3-4” inches or smaller, can have inherent moisture in it.

What Can Cause Water Damage Behind Brick Wall?

Another common cause of water behind brick a wall is wind-blown rain. This type of moisture infiltration generally takes place through the vertical joints between bricks, or head joints. The pressure of the wind pushes the water into the wall with force, over and over as the rain continues. This causes water to stream into the wall.
