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 in Building Materials
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 >
Acid stain a concrete floor by preparing the room, applying the stain, neutralizing the acid and applying a sealer. Every concrete slab reacts differently with the acid stain, so colors and patterns vary.Full Answer >
Concrete is thinner, stronger and more durable than mortar; whereas mortar is used as a bonding agent between building materials, concrete is used for structural projects, such as beams or walls. The differing compositions of these materials makes them ideal for different purposes. Concrete and mortar are not used interchangeably without compromising the structural integrity of a building.Full Answer >
The depth of footings is determined by the depth of the frost line. The top of the footing must be poured below the frost line to maintain stability.Full Answer >
