    Properties Pumice is composed of highly microvesicular glass pyroclastic with very thin, translucent bubble walls of extrusive igneous rock . It is commonly, [4] but not exclusively of silicic or felsic to intermediate in composition (e.g., rhyolitic, dacitic, andesite, pantellerite, phonolite, trachyte ), but basaltic and other ...Strength Properties of Fibrous Light Weight Concrete With ...Tests were conducted for basic strength properties like compression, split tension and flexure. From the results of the investigation important conclusions on the role of light weight aggregates in optimising the weight of concrete, the behaviour of concrete with fibres and light weight aggregates (pumice) are drawn.MITIGATES COMPACTION PUMICE AND PERLITE: .structure into soils. Pumice, by virtue of its nature-blessed, foamed-stone structure, makes an ideal soil amendment. Even crushed to soil-blending particle size, pumice retains its light, frothy, functional character, contributing to soil performance in the following ways: IMPROVES SOIL STRUCTURE. A functional root zone is critical to support
