The Romans in 127 AD used crushed pumice for aggregates in cement (light weight concrete) for walls of Pantheon in Rome
Concrete. Roman Concrete.Roman concrete was made of cement, ash, and water mainly.
Concrete was used in the Roman baths because of its practicality. Water or heat does not affect it and its durable.
The Romans
Roman concrete was invented over 2,000 years ago as a means to cheaply create a stable building material. The Romans used concrete to build most of the monuments that still stand today.
The Roman bathhouses were made of concrete with a facing in stone or bricks.
the lightweight concrete weights are depends upon their aggregates.... basically the weight of lightweight concrete is 50lb/cubic feet
J. K Nesbit has written: 'Structural lightweight-aggregate concrete' -- subject(s): Lightweight concrete
the name itself says the concrete used here is of light weight.....the best example of this kind of structure is PANTHELON....

The main difference between normal weight concrete and lightweight concrete by volume is the density of the aggregate used in the mix. Normal weight concrete contains aggregate with a density around 2400 kg/m3, while lightweight concrete uses lightweight aggregate such as expanded clay, shale, or shale to reduce the overall density of the concrete. The reduced density of lightweight concrete makes it more suitable for applications where weight is a concern, such as in construction of high-rise buildings or for insulation purposes.
To make concrete planters lightweight and durable, you can add lightweight aggregates such as perlite or vermiculite to the concrete mix. These materials help reduce the overall weight of the planter while maintaining its strength and durability. Additionally, using fiberglass or plastic reinforcement in the concrete mix can also help improve the strength and durability of the planter.
Roman concrete was no different from regular concrete, so I'm fairly sure I still do.
Lightweight concrete typically weighs between 90-115 pounds per cubic foot, which is significantly less than standard concrete that weighs around 140-150 pounds per cubic foot. The lower weight of lightweight concrete is achieved by incorporating lightweight aggregate materials, such as expanded clay, shale, or slate.

To create a lightweight concrete planter, consider using lightweight aggregates like perlite or vermiculite in the concrete mix. Additionally, using a thinner concrete wall thickness and incorporating fiberglass or plastic fibers can help reduce the weight of the planter. Lastly, consider adding drainage holes to prevent water buildup, which can add unnecessary weight to the planter.
The Latin word for concrete is solidus.
Wet concrete weighs about 4,000 per cubic yard. Some types of concrete weigh more or less. Lightweight concrete weighs about 1,000 pounds less.
