Pumice is created when a volcano furiously blasts incredibly high pressure. According to IS 2386 (Part-3 and 4)-1963 and IS 383-1970, the properties of pumice aggregate were assessed. In comparison to coarse aggregate, pumice aggregate absorbs more water. Pumice aggregate must therefore soak in water for 24 h before to usage .
2. Materials and preparation of sample 2.1.

This study examines the suitability of ceramic industrial wastes and huge amounts of basaltic pumice as a possible substitute for conventional crushed fine aggregates. Experiments were carried out to determine abrasion resistance, chloride ... Effect of crushed ceramic and basaltic pumice as fine aggregates on concrete mortars properties.
Pumice is a special stone with a bubble shape formed after a magma eruption in full contact with the atmosphere. Pumice has the characteristics of porosity, soft texture, and low specific gravity. Using pumice as aggregate can solve the problems of self-weight, poor insulation, and sound insulation in ordinary concrete.
Topçu and Uygunoğlu [128] compared separately the AR of self-consolidating concretes containing crushed limestone and pumice as aggregate by conducting the Böhme abrasion test which is a test method used for evaluating abrasion resistance of paving stones, concrete slabs and natural stones [2]. The authors reported that the self ...

Pumice-Crete ® is a low density, lightweight, low-rise structural concrete using 3/8 pumice aggregate, Portland cement, and water. The honeycomb-like walls are formed and poured at a typical thickness of 18-24 inches, with no additional structural reinforcement or insulation needed. Wall surfaces are finished inside and out with plaster (a ...
The study aimed to examine the properties of lightweight high-calcium fly ash geopolymer concrete (LWGC) containing crushed clay brick and pumice aggregates. A high …

The ignimbrite and pumice are used as crushed aggregate in the present work. The aggregate concentration of concrete specimens is designed in four different groups by using 0, 25, 50, 75 and ignimbrite and pumice, as a proportion of aggregate volume with the same water cement ratio of 0.6 and the dosage of 300 kg/m3 lightweight concrete ...
The friable nature of pumice is one of its most significant characteristics—meaning pumice is easily crushed and refined without loosing its utility: at any grade—from half-inch aggregate to microfine powder—pumice …
Different size fractions of crushed pumice sand from the island of Yali, Greece, were studied: 0.6–1.18 mm, 1.18–2.36 mm, 2.36–4.75 mm, and >4.75 mm. The density varied from about ... saturation of this kind of pumice aggregate might severely hamper its application for internal curing of concrete. Other types of LWA, for example expanded ...

Crushed ceramic and crushed basaltic pumice source were used at three levels of fine aggregate cement replacements (40%, 50%, and 60%). This study has been carried out mainly to investigate the abrasion resistance, the chloride penetration depth and the compressive strength of concrete.
This Bulletin describes types of aggregates normally used in concrete, aggregate properties affecting performance of the concrete, tests used to measure aggregate properties, and …
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
