Pumice and Concrete: Applications and Benefits of Pumice ...

Pumice concrete has several advantages over conventional concrete in many construction applications—first, and perhaps most significantly, its unique lightweight quality. This trait contributes to a decrease in structural steel costs and, consequently, job costs. Larger volumes of concrete can be handled by lighter equipment with less wear ...

Building With Pumice: Making Blocks out of Pumice, Lime ...

Nov 23, 2013  In general, pumice building members are classified as lightweight concrete, since they are produced and processed in a similar manner, the main difference being that the aggregate—namely the natural pumice—is very light, porous and water-absorbent, so that such material has to be worked somewhat differently than normal-weight concrete.

An Overview of Pumice Stone as a Cementitious Material ...

Pumice stone is a natural sponge-like lightweight aggregate formed during the rapid cooling and solidification of molten lava. After suitable preparation, it can be used as an aggregate to produce lightweight concrete or as a cementitious material to produce blended cement or geopolymer. This article focused on the influence of pumice powder (PP) on fresh properties and hardened properties of ...

Pumice - Wikipedia

Pumice is widely used to make lightweight concrete and insulative low-density cinder blocks. The air filled vesicles in this porous rock serves as a good insulator. [14] A fine-grained version of pumice called pozzolan is used as an additive in cement and is mixed with lime to form a light-weight, smooth, plaster-like concrete.
