weight of hardened concrete + 100 kgf/m3
Weight of concrete is 155 lbs/cft or 70.308 kg/cum
The weight can only be determined if the exact weight of the reinforcement, as well as the exact displacement of the reinforcing is known. Thus the weight should be 1 sq meter x thickness of the concrete minus the exact displacement of the reinforcing, plus the weight of the reinforcing. The weight per cubic meter of concrete is 2450 kg.
2400Kg/cu.m
Normal Weight Concrete at 150 pcf has an R value of 1.22 per inch thickness
Gypsum contains about 20% water by weight.
Chemical reaction of lime and dehydrated gypsum with water.
The weight per cubic yard for gypsum is approximately 2,300 to 3,000 pounds.
Gypsum is relatively lightweight compared to other construction materials like concrete or brick. It has a density of about 2.3 g/cm3, which means it is not particularly heavy.

Gypsum is added to cement to control the setting time of the cement and prevent early hydration, which can affect the workability of the concrete mixture. It also helps in preventing flash setting and cracking in the final concrete structure.
Cement or concrete was actually made very much the same way as present day concrete. The Romans used an aggregate which could be of rock, broke tiles, or brick rubble, held together with a binder of gypsum or line. The very best concrete had a volcanic ash or "pit sand" as part of the ingredients.Cement or concrete was actually made very much the same way as present day concrete.

the lightweight concrete weights are depends upon their aggregates.... basically the weight of lightweight concrete is 50lb/cubic feet
Roman concrete consisted of the same basic elements as present day concrete which is an aggregate and a binder. For the aggregate the Romans used pulverized rubble, broken tiles and rock. A volcanic debris called "pit sand" was also used. For the binder, gypsum and lime was used.
Weight of concrete is 155 lbs/cft or 70.308 kg/cum
unit weight= weight/volume.unit weight of normal concrete = 24 MPaIt is also known as density of concrete
The weight of a concrete mixer truck can vary depending on the size of the truck and if the truck is weighted with concrete it may be carrying. A concrete mixer truck is about 20,000 to 30,000 pounds without concrete.
