Lean concrete is a mix where the amount of cement is lower than the amount of liquid present in the strata. This makes it ideal as a base layer where other kinds of concrete are placed on top. It is good for providing a flat bottom in uneven or dirt terrain.Know More
Concrete with high water content is considered lean because it has a lower concentration of cement compared to other kinds of paving and building materials of that class. It is often used as a plaster between bricks or other pieces of infrastructure to create a tight seal. Lean concrete cracks over time when it is not applied properly or mixed to the right specifications. Careful preparation is key to successful lean concrete.
Lean concrete is commonly used in road construction as the lowest level under the pavement on which vehicles travel. It serves as a sub-base in projects where the ground itself is not a suitable resting place for a project to begin, thereby giving roads and buildings a stable platform on which to rest.
A lean concrete mix is measured in pounds per square inch. In the right conditions, lean concrete flows like a liquid and makes for easy applications. It usually is not used in cases where more than 2 inches of sub-base or ground clearance is necessary.Learn more about Building Materials
It will take 60 60-pound bags of ready-mix concrete to make one cubic yard of concrete. This yield is approximate and does not include allowance for uneven subgrade, waste, etc.Full Answer >
Color existing concrete by cleaning the surface, applying a transparent stain. After 4 hours, inspect the concrete to determine if you need a second coat and applying it. After applying the sealer, allow sufficient time for the sealer to cure before allowing traffic on the surface.Full Answer >
Concrete is a mixture of cement, water and aggregates, such as sand, coarse gravel or crushed rock. After it hardens, concrete is resilient, durable, resistant to environmental extremes and capable of supporting heavy loads. Grout is similar to concrete in its ingredients, but with a fine aggregate grade and a higher water content that allows it to flow easily and be used as a filler or joint sealer.Full Answer >
Concrete slabs should be 4 inches thick for normal residential construction. A slab should be 5 to 6 inches thick if heavy vehicles, such as motor homes or garbage trucks, will be parked on the concrete slab.Full Answer >
