In the less developed parts of southern Africa, where agriculture is crucial in daily survival, agricultural lime is often difficult to obtain. This is due to the scarcity of production sites, high transport costs and inadequate support for farmers from government extension services. In Zambia there are upwards of 700,000 small-scale farmers who struggle to farm on acid soils and as a result ha...

Low-iron, manganese-enriched (LIME) olivine grains are found in cometary samples returned by the Stardust mission from comet 81P ⁄Wild 2. Similar grains are found in primitive meteoritic clasts and unequilibrated meteorite matrix. LIME olivine is thermodynamically stable in a vapor of solar composition at high temperature at total pressures of a millibar to a microbar, but enrichment of solar c...

In order to study the application of lime-fly ash loess in permafrost subgrade engineering, uniaxial compressive test, fast direct shearing test and permeability tests were carried out on lime-fly ash loess under different curing ages and freeze-thaw cycles. Uniaxial compressive strength of lime-fly ash loess increases slowly with the curing ages, and can reach 3.5 Mpa after the curing ages of ...

This research provides a characterization of ancient Roman mortars from “Villa del Capo di Sorrento” (commonly known as Pollio Felice” or “Bagni della Regina Giovanna”). A deepened analysis cementitious binding matrix and aggregates was conducted with the aims determining possible sources raw materials mix recipe, to evaluate minerogenetic secondary processes. Twenty samples taken Villa were in...

If the anaesthetic circle system is arranged to increase the humidity of fresh anaesthetic gases by placing the carbon dioxide absorbent canister between the fresh gas inlet and the patient, drying of the soda-lime can occur. Very dry soda-lime adsorbs significant quantities of halothane. Using fresh soda-lime, effluent halothane concentration reached 50% of the input concentration in 35s, but ...

The River Yläneenjoki catchment in southwest Finland is an area with a high agricultural nutrient load. We report here on the nutrient removal performance of three on-site lime-sand filters (F1, F2, and F3), established within or on the edge of the buffer zones. The filters contain burnt lime (CaO) or spent lime [CaO, Ca(OH), and CaCO]. Easily soluble lime results in a high pH level (>11) and l...

Masonry walls exhibit low tensile strength and high material heterogeneity, which makes them especially vulnerable against cyclic loading conditions, such as those typical in earthquakes. This paper presents the experimental results obtained from tests on three masonry reinforced with textile mortar (TRM) materials subjected to in-plane loading. These full-scale were tested LARGE laboratory at ...

A new approximate mortar condition is proposed for the lowest order CrouzeixRaviart finite element on nonmatching grids, which uses only the nodal values on the interface for the calculation of the mortar projection. This approach allows for improved and more flexible algorithms compared to those for the standard mortar condition where nodal values in the interior of a subdomain, those closest ...

Abstract In mortars, the use of fibres has been diachronically a commonly used technique. Ancient Greece, wood and straw were particularly to increase volume stability in clay lime mortars. Overtime, with evolution technology, natural replaced by modern materials like polypropylene, steel, glass carbon fibres. Recently, climate change strong demand for independence from non-renewable mineral re...

The use of ground granulated blast furnace slag (ggbs) is well established in many cement applications where it provides enhanced durability, including high resistance to chloride penetration, resistance to sulphate attack and protection against alkali silica reaction (ASR). The use of ggbs in soil stabilization is, however, still a novel process in the UK although it has been used in South Afr...
