Concrete is one of the most widely used construction materials in the world, but different types of concrete are suitable for different applications and construction projects. Lightweight concrete mixtures are made with lightweight coarse aggregate, which creates lighter versions of standard concrete mixtures and provides numerous benefits to the building industry. Our knowledgeable concrete contractors at Best Concrete Mix Corp. in Flushing, New York, provide numerous types of concrete to a diverse clientele, including lightweight concrete mixtures to meet your specific construction needs.
Standard concrete typically includes a mixture of crushed natural stone, cement, water and sand. The density of the stone increases the overall weight of the concrete mixture, which increases the cost of transportation. Lightweight concrete mixtures use various alternate aggregate materials, such as more porous rock or manufacturing by-products, which may include pumice, fly ash, slag, clay, shale or slate. While the differences in composition don’t significantly impact the compressive strength, lightweight concrete has a significantly longer drying process and may have a reduced structural weight after it’s dried.
Advantages Of Lightweight Concrete
Due to the lowered weight of lightweight concrete, there’s less weight on a building’s structural load. This makes it an ideal product when you need to reduce a building’s load, which is especially important in tall buildings and projects that would otherwise have to be abandoned because of excessive weight. Other advantages of lightweight concrete include:
- Reduced weight of wet concrete that allows longer spans to be poured with reduced formwork and propping, which saves on time and labor costs
- Savings in foundation and reinforcement due to reduced dead load
- More economical lower haulage weight
- Improved thermal properties with relatively low thermal conductivity
- Improved fire resistance
Lightweight Concrete Applications
Lightweight concrete has numerous applications, depending upon its composition. Some common applications include:
- Roofing tiles
- Garden pavers
- Insulating walls
- Long-span bridges
- Floor underlayment
- Reinforced concrete
- Insulating water pipes
- External walls of small homes
- Thermal insulation for protecting steel structures
- Partition walls and panel walls in frame structures
- Walls with wood or other materials being attached by nails
