Traditional lime-sand mortars, using fat lime as the binder, have proved to be durable over many centuries. From the builder s viewpoint, however, they became uneconomic, as they set slowly by loss of water and hardened even more slowly by absorption of carbon dioxide, forming a calcium carbonate-bonded... 

Fat lime is used to describe a quick- or hydrated lime, having a high volume yield and producing a plastic putty. It is also used for relatively pure quick- or hydrated lime, as opposed to impure and hydraulic limes. 

And the puzzolaiia was formed by calcining, at a heat not great, a mix ture of four parts of earthy clay measured in paste, and one part of fat lime measured in the same way—the mixed pastes being formed into smalt prisms, dried in the sun, calcined and pulverised. 

Figs. 4, 5, 6, 7 and 3, represent Mr. Petot s curves of energjf of fat lime, hydraulic lime—plaster-cements —calcareous puzzolanas, and clay. 

Rich or fat limes are those which double their volume in slacking arid dissolve in fresh water to the last particle. They absorb about 300 per cent, of their weight of water. 

Such care includes washing of the filter material with the spray jets after every period of use, removal of grease and fats with warm soap solution if clogged, treatment with diluted hydrochloric acid for removal of lime encrustations, maintenance of scraper bade in careful adjustment to filter drum to prevent tearing of the filter material.

The waste products of a home include paper, containers, tin cans, aluminum cans, and food scraps, as well as sewage. The waste products of industry and commerce include paper, wood, and metal scraps, as well as agricultural waste products. Biodegradable wastes, such as paper fines and industrial biosludge, into mixed alcohol fuels (e g., isopropanol, isobutanol, isopentanol). The wastes are first treated with lime to enhance reactivity. Then, they are converted to volatile fatly acids (VFAs) such as acetic acid, propionic acid, and butyric acid, using a mixed culture of microorganisms derived from cattle rumen or anaerobic waste treatment facihties. 

Uses of the alkali hydroxides.—A soln. of potassium hydroxide is used in the laboratory as an absorbent for carbon dioxide, the sodium compound is not so often used because of the formation of less soluble sodium carbonate which is liable to choke the delivery tubes with crystals. Potassium hydroxide is used in making soft soaps the corresponding sodium compound gives the ordinary hard soaps. The hydroxide fused with a little lime is used as a cautery—pierre a cautere. The alkali lye is also used as a cleansing fluid, since it forms soluble soaps with many greases and fats. The lye also dissolves animal tissues. 

Bating,—With respect to the removal of lime from the skin, it has been found that no amount of scraping and rinsing is capable of making a perfect separation, a portion of the earth being retained in the pores of the skin, combined w, tk, perhaps, some of the decomposing tissue, and with the grease and fat of the hide, as a lime soap. These combinations, if not altered and VOL. it. 

Under the name of adtpocm, Fourcroy described a peculiar fatty substance found in a cemetery at Pans, and supposed to have been partly formed during decomposition. Ciievreul has shown that this matter is the original fat of the body, which has resisted putrefaction, and is partly in the state of fatty acid, and partly as ammonia soap, with traces of lime and magnesian soaps. This substance may often be found in tho neighborhood of graveyards. 

Tikis ash contains carbonate of soda sometimes to tho amount of ninety-five or ninety-six per cent, It is, however, essentially necessary in the production of soap, that the alkali should bo rendered caustic—-that Is, set free from combination by the removal of carbonic acid as, if it be in chemical union with any other body, it has no decomposing power over the oils or fats. Even if combined with the weakest acids, saponification will not ensue and the greatest care should, therefore, be exercised in tin s preliminary process—the preparation of the lies. The process for causticlzing is the same in principle for tile preparation both of soda and potassa lies, It depends upon tiro greater affinity of lime than of soda or potassa for carbonic acid, and the decomposition is one of tho most simple, thus—...
