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.

The grading of an aggregate has a considerable effect on the workability and stability of a concrete mix and it is for this reason that grading of both the pumice lightweight aggregate and the normal aggregate was carried out to establish whether pumice qualifies as an aggregate according to BS 882 [5]. The following procedure was followed in

The aggregates obtained from the quarry are blended to satisfy code requirements. 45% of the sample mass with size of 12.5 mm finer and 9.5 mm coarser scoria aggregates was added during coarse scoria aggregate blending. Similarly, 47% by mass of the sample passing 1.18 mm sieve is added during fine scoria aggregate blending. The particle size

2. Observations on pumice aggregates 2.1 General Pumice is a volcanic rock whose porous structure is formed by dissolved gases precipitated during the cooling as the lava hurtles through the air. The connectivity of the pore structure may range from completely closed to completely open [12].

Pumice Aggregates. Pumice aggregates are used as a lightweight aggregate in construction, lightweight concrete, precast concrete, concrete block manufacture and fence posts. They are also used as geotechnical fill where a lightweight material is specified due to loading concerns. The other main area of use is as a substrate in green roof ...

One way is to incorporate a lightweight aggregate. Natural lightweight aggregates such as pumice [most widely used], scoria, volcanic cinders, tuff and diatomite. Or artificial aggregates or rotary kiln produced lightweight aggregates such as expanded clays, slates, slag, perlite or shale's. Cenospheres

LIGHT WEIGHT AGGREGATES. One of lightweight aggregates characteristics is their high porosity which is the cause of less specific weight. Some of the lightweight aggregate is available naturally while others are produced artificially (Neville and Brooks, 1987). As the natural aggregates Pumice, mineral aggregate and volcanic ash can be mentioned.
