LECA-like materials can be traced back to ancient Mediterranean civilizations (Chandra and Berntsson, 2002).LECA is a subtype of light weight aggregates (LWA), a heterogeneous group of low-density materials used for various civil engineering and construction purposes (Al-Jabri et al., 2005; Holm and Valsangkar, 1993; …
Normal porosity: If the strand floats somewhere in the middle of the glass, you probably have medium or normal porosity hair. High porosity: If the strand quickly sinks to the bottom of the glass ...
If density porosity is less than neutron porosity, such as in a sandstone with shale/clay content, the density log provides a reasonable approximation of formation porosity. ... The point defines the lithology of the formation by which line it falls on and the porosity is the value marked on the line at that point. Point falls away from ...
Most commercially produced growing media have a total pore space of 60 to 80%. The recommended air porosity range for a growing medium varies by crop and the crop production stage: for germination or plug propagation media with fine components, it is recommended to have 10 – 15% air porosity, while for most general greenhouse crop …

The production of new cement-based materials with high strength, low density, and strong thermal qualities for energy-efficient structures was investigated. Pumice, expanded clay, perlite,
The main aim of the study is to obtain a new, innovative method for the organization of combustion processes in fluidized bed reactors.A key aspect of the change in the organization of the fluidized bed combustion process is the creation of a fluidized bed made out of lightweight expanded clay aggregate (LECA). The new fluidized bed has a …
varying sizes. The inside of the aggregate has a black sponge texture with 73–88 % porosity. The high porosity of the aggregate causes improvement in some properties such as low weight, low heat conductivity, sonic loss, and high resistance against firing. The aggregates have a coating with a thickness of about 50–100 µm. The
This paper determines mix proportions of high-strength structural lightweight concrete (HSSLWC), which reduces the weight of concrete by using expanded aggregate clay (Leca). In order to produce HSSLWC, mineral and chemical admixtures have been used along with limestone that reduces porosity and increases strength. Tests for …
The as-prepared porous HE (Zr 0.2 Hf 0.2 Ti 0.2 Nb 0.2 Ta 0.2)C has homogeneous porous structure with grain size in the range of 100–500 nm and pore size in the range of 0.2–1 μm, and possesses low density of 0.97 g/cm 3, high porosity of 80.99%, high compressive strength of 3.45 MPa, low room temperature thermal …
According to the above, it can be concluded that the different organic and inorganic additives (like SiO 2, soda-lime silica glass, CaF 2, automobile oil, carbon …

For low porosity hair, where moisture absorption is as critical as retention, you need hair oils that are lighter in molecular weight, non-comedogenic, and brimming with essential fatty acids that can navigate compact …
LWAC has a fairly high porosity (Chung et al. 2021) and low density as a result of embedding porous lightweight ingre-dients (Mehta and Monteiro 2014). Further, the LWAC is used to enhance the energy eciency of building structures by reducing the required thermal energy up to 15% versus to normal weight concrete (Real et al. 2016). …
Pebble density. The density of your clay pebbles is an important factor in how it will perform as a potting medium. Pebble density is rarely advertised directly for most LECA products, but sometimes brands will offer an average porosity of their product. Porosity is a measure of the empty space within the structure of the clay pebble. A good ...
The porosity ranges from 8.0% to 36.0%, or 30.0% on average, and the permeability ranges from 0.18×10 −3 – 250×10 –3 μm 2 or 7.3×10 –3 μm 2 on average, thus it is a typical high porosity and low permeability carbonate reservoir char- acterized by thin stratum, high heterogeneity and poor devel- oped fractures.
